Polymorphism of hafnate and zirconate of calcium

Creators

Description

Polymorphism of calcium hafnate and zirconate within 20-2300 deg C temperature range in the air is shown by high-temperature X-ray analysis. Formation of new polymorphous forms, that is: rhombohedral tetragonal 1 and tetragonal 2 - is determined. Parameters of unit cells are determined
