Refined white ceramic material and method for preparing same

摘要

Disclosed is a refined white ceramic material, which belongs to the field of ceramic materials for component packaging, and comprises the following raw materials by weight in percentage: aluminum oxide 87-93, magnesium oxide 0.8-5, silicon dioxide 1-6, calcium oxide 0.6-4, titanium dioxide 0.01-0.5, and zirconium dioxide 0.5-3. The method for preparing same comprises: (1) washing aluminum oxide grinding balls and a ball-milling tank, and drying for later use; (2) weighing a solvent NP-10 of 0.5-4 by weight in percentage, and adding the solvent into the ball-milling tank; (3) weighing raw materials, adding the raw materials into the ball-milling tank, and performing ball milling for 72±0.5 h. By means of the refined white ceramic material of the present invention, the obtained ceramic grains have even sizes, small surface roughness, and high fracture resistance performance of ceramic body.
