LEAD TUNGSTATE Usage And Synthesis

Chemical Properties

white powder(s); used as a pigment [HAW93]

Definition

scheelite: A mineral form of calciumtungstate, CaWO4, used as anore of tungsten. It occurs in contactmetamorphosed deposits and veindeposits as colourless or white tetragonalcrystals.

General Description

White to pale yellow powdery solid. Sinks in water.

Reactivity Profile

LEAD TUNGSTATE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

INHALATION: Joint and muscle pains, headache, dizziness and insomnia. Weakness, frequently of extensor muscles of hand and wrist (unilateral or bilateral). Heavy contamination - Brain damage. Stupor progressing to coma - with or without convulsion, often death. Excitation, confusion, and mania less common. Cerebrospinal pressure may be increased. INGESTION: Abdominal pain, diarrhea, constipation, loss of appetite, muscular weakness, headache, blue line on gums, metallic taste, nausea and vomiting, joint and muscle pain.
