Five chemical compositions constitute these pigment classes. Medium chrome yellow is essentially PbCr04 and is the reddest hue of yellow. Solid solutions of PbCr04 with PbS04 in varying proportions yield primrose and lemon chrome yellows. Their hue difference is also attributable to the their polymorphic nature— primrose yellow is orthorhombic in crystal structure and lemon yellow is monoclinic. The less stable orthorhombic crystal is treated during primrose yellow manufacture to minimize hue shifts and conversion. [Pg.135]

Precipitation conditions determine crystal structure. Lemon chrome yellows are precipitated hot with excess lead to form the monclinic crystal. Primrose yellow is preciptated at a lower temperature to form the orthorhombic crystal. Chrome oranges are precipitated under alkaline conditions. The higher the alkalinity, the larger the particle. The precipitation of molybdate orange is complicated by the polymorphic nature of two of the components of the solid solution precipitate lead chromate and lead sulfate. As with primrose yellow, the crystal is stabilized after precipitation to prevent conversion. [Pg.135]

Barium chromate finds its way into the market as a pigment under various names, such as barium chrome, lemon chrome, and yellow ultramarine. It is very permanent, but is deficient in brightness and body, and is therefore not widely used. [Pg.47]

Lemon chrome This is a greenish-yellow pigment (slightly redder than primrose) with a monoclinic crystal structure, which is more stable compared to other crystal forms. The undertone is dependent on the lead sulfate content - the more sulfate, the greener the shade. [Pg.179]
