Anwendungen & Verwendung
Beschreibung
Lead(II) oxide occurs in two polymorphs, red, having a tetragonal crystal structure and yellow, having an orthorhombic crystal structure. Both forms occur naturally as rare minerals. The red form is known as “Litharge” and the yellow form is known as “Massico”.
Verwenden
Lead(II) oxide is employed mostly in lead-based industrial glass and industrial ceramics, including computer components. It is used as an intermediate/precursor in the manufacture of several products, for example water proof cements, lubricants, lubricating oils, inorganic pigments, lead soaps, petroleum refining, rubber, cathode ray tube glass, and polyvinyl chloride (PVC). It is useful for lead acid batteries as cathode and anode. Lead monoxide scores significant applications in oil, gas and chemical manufactures. It is an efficient catalyst for condensation reactions in organic synthesis.
