ZINC OXIDE POWDER FOR PREPARING ZINC OXIDE SINTERED BODY WITH HIGH STRENGTH AND LOW THERMAL CONDUCTIVITY

The zinc oxide powder has a crystallite size of 20 to 50 nm as determined by X-ray diffraction, a particle diameter of 15 to 60 nm as determined by the BET method, a loose bulk density of 0.38 to 0.50 g/cm, and a tapped density of 0.50 to 1.00 g/cm. The zinc oxide powder has a small number of bound...

Beschreibung
Zusammenfassung:	The zinc oxide powder has a crystallite size of 20 to 50 nm as determined by X-ray diffraction, a particle diameter of 15 to 60 nm as determined by the BET method, a loose bulk density of 0.38 to 0.50 g/cm, and a tapped density of 0.50 to 1.00 g/cm. The zinc oxide powder has a small number of bound particles and a high tap density, and is useful as a raw material for obtaining a zinc oxide sintered body exhibiting high strength and low thermal conduction.
