Embodiment Construction

[0028] Give an embodiment below and describe in detail as follows:

[0029] The steps of the preparation method of the present invention are as follows:

[0030] one,The two main raw materials, fused alumina and zirconium silicate, are selected separately to ensure good crystallization, white color, and no impurities. The content of alumina in the fused alumina raw material should be greater than 99%, and the particle size should be less than 300 mesh, the content of zirconium silicate in the zirconium silicate raw material should be greater than 98%, and the particle size should be less than 350 mesh;

[0031] two, Ball milling, rounding and water washing: A: Alumina ball milling: use stainless steel grinding balls; the weight ratio of the material to the ball is 3:1, controlled by PLC, the grinding-time speed curve is a sinusoidal curve, the maximum speed of the ball mill is 4 revolutions per minute, One grinding cycle is one hour;

[0032] Circularization, the rounding...

Abstract

The invention discloses special zirconium-aluminium composite ground micro-powder for the optoelectronic industry and a production method for the same. The special zirconium-aluminium composite ground micro-powder for optoelectronic industry is produced from two main raw materials, namely, fused alumina and zirconium silicate, via ball-milling, water-washing, grading, compounding, surface coating, filtering, spray-drying and sieving, wherein the compounding ratios of the contents of the raw materials are as follows: the content of alumina particles is 30-50%, and the content of zirconium silicate particles is 70-50%. The product disclosed by the invention is reasonable in particle shape collocation, wide in particle size distribution, stable in median diameter, high in basic particle size ratio, without large particles and ultrafine particles, excellent in interparticle lubrication property, and especially suitable for grinding and polishing high-tech products in the optoelectronic industry.

Description
