English description（英文原文，共 1308 字符）
Product Name:Lead(II) oxide
English Name:Lead(II) oxide
CAS No.:1317-36-8
Aliases:Lead monoxide, Litharge, Massicot, Lead oxide (PbO)
Molecular Formula:PbO
Physical Properties:Relative molecular mass approx. 223.20. Usually appears as a red powder and exists as red tetragonal crystals (litharge) and yellow orthorhombic crystals (massicot). Melting point 886 °C, boiling point 1472 °C, density 9.53 g/cm³ (tetragonal) or 8.0 g/cm³ (orthorhombic), transition point 488.5 °C. Insoluble in water, soluble in acids to form lead(II) salts, slightly soluble in strong alkalis to form plumbites; readily reduced to metallic lead by hydrogen, carbon or carbon monoxide on heating.
Uses:Mainly used in the manufacture of lead glass, ceramic glazes and pigments, as well as in lead-acid battery plates, rubber vulcanization accelerators and chemical catalysts. It is also widely applied in optical glass, radiation shielding materials and chemical analysis.
Technical Specifications:
Lead(II) oxide (PbO) content: ≥99% (first grade ≥99.3%, analytical grade ≥99.7%)
Metallic lead content: ≤0.2% (first grade and analytical grade ≤0.1%)
Lead dioxide content: ≤0.1% (first grade and analytical grade ≤0.05%)
Insoluble matter in nitric acid: ≤0.2% (first grade and analytical grade ≤0.1%)
Water content: ≤0.2%
