Chrome yellow is a yellow pigment made by adding a soluble lead salt (nitrate or acetate) to a solution of alkali chromate or dichromate.
Pigment Lemon Chrome is a crystalline mineral consisting of lead(II) chromate that can vary in hue from primrose yellow to orange, depending upon the particle size, which, in turn, depends on the conditions of precipitation.
Lighter hues, such as chrome yellow primrose, usually contain lead sulfate, or other insoluble lead salts.
The middle hues are neutral lead chromate, and the orange chromes are basic lead chromate.
Pigment Lemon Chrome consists of very fine particles that are dense and opaque.
Appearance: Lemon powder, It is Bright color, strong tinting strength,high hiding with good light fastness and dispersibility.
Main Application: solvent based paint: Alkydresin, Amino-baking, N/C , Epoxy; Plastic: Masterbatch, cable material, plastic pipeand plastic film and sheet etc.
Suggested for polyurethane paint,architectural coatings, water based coatings, color paste, leather, stationery and rubber.
Chrome yellow is lead(II) chromate (PbCrO4).
Pigment Lemon Chrome occurs naturally as the mineral crocoite but the mineral ore was never used as a pigment for paint.
After the French chemist Louis Vauquelin discovered the new element chromium in 1797 lead chromate was synthesized in the laboratory and used as a pigment beginning in the second decade of the nineteenth century.
Chrome yellow had been commonly made by mixing solutions of lead nitrate and potassium chromate and filtering off the lead chromate precipitate.
The pigment tends to react with hydrogen sulfide and darken on exposure to air over time, forming lead sulfide, and it contains the toxic heavy metal lead plus the toxic, carcinogenic chromate.
For these reasons, it was replaced by another pigment, cadmium yellow (mixed with enough cadmium orange to produce a color equivalent to chrome yellow).
Darkening may also occur from reduction by sulfur dioxide. Good quality pigments have been coated to inhibit contact with gases that can change their color.

When chrome yellow was first introduced as a pigment in the early part of the nineteenth century, it provided a bright, opaque yellow on the artists’ palette.
However, Pigment Lemon Chrome suffered a flaw in its original form—it darkened upon exposure to light.
Chrome yellow enjoyed a brief history of widespread use among nineteenth century artists, such as Turner, Manet, Cézanne, Monet, and Pissarro.
Cézanne, like Pissarro and Monet, used the neutralizing effect of combining three primary colors—ultramarine, vermilion and chrome yellow—to make colored grays.
Pigment Lemon Chromes popularity soon faded because a more stable opaque pigment, cadmium yellow, was introduced by the middle of the century.
The Impressionists’ highly complex paint mixtures of primaries were solutions to the problems of rendering plein air light effects and modeling forms in space.
Equivalents were sought in material colors for the effects of light because they realized ‘sunlight cannot be reproduced, but it must be represented.’
Pigment Lemon Chrome is not so much the brilliance of each individual color that produces a high key picture as the juxtaposition of certain colors, so that they enhance each other’s color and brightness.

Chrome yellow is a yellow pigment made of lead(II) chromate(PbCrO4).
Pigment Lemon Chrome was first extracted from the mineral crocoite.
The color range is lemon, light, orange, medium and deep chrome yellow.
Pigment Lemon Chrome is gloss, bright color shade and excellent hiding power,mainly used for producing coating, paints, inks, plastic, rubber etc.
Chemical formula: PbCrO4.xPbSO4.yAl(OH)3
A toxic yellow artist’s pigment containing Lead chromate sometimes mixed with Lead sulfate.
Lead chromate can range in shade from lemon yellow to orange depending on its particle size, hydration state, and percent lead chromate.
Chrome yellow, which came on the market in early 1800s, is permanent to visible light, but can darken with exposure to UV radiation or Hydrogen sulfide.
Chrome yellow is used in industrial paints, some artist’s paints and ceramic glazes.
Other yellow chromate pigments are sometimes also called chrome yellow.
Strontium chromate, zinc chromate, and Barium chromate are pale yellow pigments that are often mixed and called lemon yellow.
Strontium chromate has more hiding power than the barium chromate. Zinc yellow is synthetically prepared zinc chromate.
The pure material is stable and is used in oil and watercolor paints.
Chrome yellow pigments were invented in the early nineteenth century, with hues ranging from lemon-yellow to deep orange-yellow depending on the composition and crystal structure of the pigment.
Chrome yellow can be denoted with the general formula PbCr1−xSxO4 (0 ≤ x ≤ 0.8).
Chrome yellows that do not contain any sulphate (x = 0) are medium yellow in colour and have a monoclinic crystal structure, while the more orange-yellow varieties contain some chrome orange (Pb2CrO5) in addition.
The lighter varieties show variable amounts of sulphate and might exist in both the monoclinic and orthorhombic crystal structure, the latter becoming favorable when higher amounts of sulphate are present

Lead chrome pigments are isomorphous blends of lead chromate with lead sulphate, the composition of which corresponds to the formula PbCrO4- n PbSO4l, where n can be within the range from 0 to 2.
Additionally, the chrome pigments can contain modifying additives [А1(ОН)3, Ti(OH)4, surfactants, etc.].
The color of the chrome pigments varies from yellow to light lemon yellow; under otherwise equal conditions, the more is the РbСrО4 content, the more yellow are chrome pigments.
The chrome pigments can crystallize in both rhombic and monoclinic systems, the latter being more stable. While having the same chemical composition, lead chromates and sulphochromates crystallizing in rhombic system are considerably lighter and finer grained than those crystallizing in monoclinic system.
Specific surface: 16–30 m2/g, refraction index: 2.7, particle size: 0.2 to 2–3 μm, particle shape: granular or needle-shaped, aqueous extract рН: 5.0-7.0.
The chrome pigments are hydrophobic, insoluble in water and organic acids, but soluble in hydrochloric and nitric acids.
They redden under the action of alkalis (basic lead chromates are formed) and darken under the action of H2S (PbS is formed); therefore the chrome pigments must not be mixed with sulphur-containing pigments.
The thermal stability of the chrome pigments is up to 90°C; their light resistance is rather low.
In oily coatings, the chrome pigments change their ground tint with the course of time: they become green (Sg6+–► Sg3+) and dark due to formation of lead peroxide compounds.
The chrome pigments are weather and corrosion resistant, and have high coverage rates.
The chrome pigments of monoclinic modification have better light resistance and covering power and relatively lower dispersion and coloring power than the chrome pigments of rhombic modification.
The most common methods of production of lead chrome pigments are the followings: sedimentation from the basic lead acetous and nitric compounds, continuous method of producing the chrome pigments from Рb metal as well as from yellow lead monoxide and chromic anhydride.
Although lead sulphate crystallizes in the same two systems as lead chromate does, its stable form is the rhombic modification.
Therefore, introduction of lead sulphate into the composition of the chrome pigment increases the stability of rhombic modification of lead chromate in isomorphous blend.
In addition, the following additives are recommended to introduce when synthesizing the chrome pigments to stabilize the rhombic modification of lead chromates and sulphochromates: lead phthalate, aluminum hydroxide, titanium hydroxide and some surfactants.
