blue-gray metal, soft. Melting point 327.4 °c, Boiling Point 1740 °c. dj0 11. 34. Resistivity cn.cm) 20. 65 (20 °c);27. 02 (100 'IC);54. 76 (320 °c); 96.74 (330 °c). Viscosity of lead in the molten state (cp):3.2(327.4 °c);2.32(400 °c);1.54 (600 °c);1.23 (800 °c). Insoluble in water, soluble in nitric acid, hot concentrated sulfuric acid, alkali. When the powder is heated, exposed to open fire or exposed to oxidant, it will cause combustion explosion.
99. 999% high purity lead was obtained from lead ingot after electrorefining. Then 99. 999% high-purity lead can be obtained by electrolytic refining with 99. 9999% high-purity lead as raw material.
is used for manufacturing compound semiconductors, infrared photoelectric conversion devices, temperature difference elements, and the like. Also used in the production of various batteries, Fuse, lead plate, metallurgical and chemical equipment lining and X-ray protective layer.
inhalation of dust can damage the hematopoietic, nervous, digestive system and kidney. Manifested as chronic poisoning. Short-term exposure to large doses can occur acute or subacute lead poisoning. Store in a cool, ventilated warehouse. Keep away from fire and heat source. Keep the container sealed. Should be stored separately from oxidants and acids.
