主な用途／役割
真珠色用無機系着色剤。
説明
Lead phosphate is white powder soluble in acids and alkalis. Lead (II) phosphate is insoluble
in water and alcohol but soluble in nitric acid and has fixed alkali hydroxides. On
heating, it decomposes and emits very toxic fumes containing Pb and POx.
Reports have indicated that on the basis of sufficient evidence of carcinogenicity in experimental
animals and inadequate evidence for the carcinogenicity in humans, lead acetate
and lead phosphate are reasonably anticipated to be human carcinogens. Information on
the toxicology profile of lead phosphate is limited.
化学的特性
Lead phosphate is a white powder or colorless
crystals.
使用
Stabilizer for styrene and casein plastics; in special glasses.
一般的な説明
White powder.
空気と水の反応
Insoluble in water, soluble in acids and alkalis.
反応プロフィール
Salts, basic, such as LEAD (II) O-PHOSPHATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

不和合性
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides, and active metals.
廃棄物の処理
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
