中鉻黃是以硝酸鹽如硝酸鉛、鉻酸鹽如重鉻酸鈉為原料，嚴格控制各種反應條件形成穩定的單斜晶形中鉻黃粒子，經過濾、乾燥、粉碎而成。主要用於塗料，尤其是路標塗料、油墨和塑膠等。Lead chrome yellow,the molecular formula is 25PbCrO4·PbO.The color range is from lemon yellow to orange yellow. It is usually classified 5 standard types as lead chrome yellow,light chrome yellow,medium chrome yellow,deep chrome yellow,chrome orange yellow.The pigments are gloss,bright color shade and excellent hiding power,mainly used for producing coating,paints,inks, plastic, rubber,cultural&educational articles etc.
