CE ÎNSEAMNĂ LEAD MONOXIDE ÎN ENGLEZĂ?
Plumb (II) oxid
Oxidul de plumb, denumit și monoxid de plumb, este compusul anorganic cu formula moleculară PbO. PbO are loc în două polimorfe, una având o structură de cristal tetragonală, iar cealaltă având o structură de cristal ortorombic. Aplicațiile moderne pentru PbO sunt în principal în sticlă industrială pe bază de plumb și ceramică industrială, inclusiv componente de calculator.
