SYNTHESIS METHOD OF CERAMIC ON BASIS OF ZINC OXIDE Russian patent published in 2010 - IPC C04B35/453 C04B35/64 

FIELD: metallurgy.

SUBSTANCE: sintering of pressed mixture of powder of zinc oxide with alloy additions at least at the first stage, is implemented at excess partial pressure of zinc over partial pressure of oxygen. Mentioned conditions are achieved, particularly at implementation of burning in closed volume at presence of metal zinc, in closed volume at presence of degasifier of oxygen, and also at burning in thermal-resistant gas-proof linings, as in vacuum, as in ambient air, or during burning in linings with aluminium gasket. The first stage of burning is implemented at temperature not less than 900°C during not less than 1 hour. Proposed method will give the ability to receive ceramic on the basis of zinc oxide c with achieving of theoretically possible densities and with high uniformity.

EFFECT: high grade of layers, applied from ceramic targets.
