Stirred reacting and grinding processing method for production of high purity alpha-aluminum oxide, silicon carbide micron, nanometer grade powder material

Abstract

The invention relates to a stirred reacting and grinding processing method for production of high purity alpha-aluminum oxide, silicon carbide micron, nanometer grade powder material, which can effectively solve the market requirement problem for the production of the high purity alpha-aluminum oxide, silicon carbide micron, nanometer grade powder material for piezocrystal precision and minuteness processing. The technical proposal of the method is that: alpha-aluminum oxide or silicon carbide powder, water and an activating agent are added into a mixer respectively to react by stirring and be ground, wherein the ratio of the alpha-aluminum oxide or silicon cabide powder and water by weight is 1:5, dosage of the activating agent is 0.03 percent of the sum of the alpha-aluminum oxide or silicon carbide and the water by weight; while mixing, stirred reacting and grinding, the activating agent which is 0.03 percent of the sum of the alpha-aluminum oxide or silicon carbide and the water by weight is added into the mixture, so that after the materials react by sufficiently stirring and are ground, the materials are subjected to overflow separation, and are collected. The method is simple and unique, has low production cost and easy operation, the processed product has high purity and good quality, and has enormous economic and social benefits.

Description

1. Technical field [0001] The invention relates to a material processing method, in particular to a stirring reaction grinding treatment method for producing high-purity α-aluminum trioxide and silicon carbide micron and nanometer powder materials. 2. Background technology [0002] α-Al2O3 (α-Al 2 o 3 ), silicon carbide (SiC) micron-scale and nano-scale materials are key materials for piezoelectric crystal production and micro-processing, and are widely used in information industry, national defense and aviation and other fields, including military, civilian, medical and commercial aspects. It has a wide range of uses, but due to the difficulty and high cost of high-purity α-alumina and silicon carbide production, most of the imported products are used in my country at present, and there is no mature production method, especially for commercial purposes. The secrecy and blockade are very strict, and it is difficult to know what methods are used abroad. Especially with the ac...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the existing technical difficulties, the object of the present invention is to provide a stirring reaction grinding treatment method for producing high-purity α-alumina, silicon carbide micron and nano-scale powder materials, which can effectively solve the problem of pressure The production of high-purity α-aluminum trioxide and silicon carbide micron and nano-scale powder materials for the micromachining of transistors can solve the problem of market demand. The technical solution is to use α-aluminum trioxide or silicon carbide powder (Powder is made of α-alumina or silicon carbide pulverized by a pulverizer, conventional technology) Add water and active agent to the mixer respectively, mix and stir for reaction and grinding, α-alumina or silicon carbide powder The weight ratio to water is 1:5, and the amount of active agent added is 0.03% of the weight sum of α-alumina or silicon carbide and water. While mixing, stirring, reacting and grinding, add α-alumina or carbonization Silicon, water and activating agent weight and 0.03% activating agent make the material fully stirred and reacted and ground, then overflowed and classified, collected, the processing method of the present invention is simple, unique, low production cost, easy to operate, and the product purity of processing and production High quality, good quality, fully meet the requirements of high-purity α-aluminum trioxide, silicon carbide micron and nanoscale powder materials for piezoelectric crystal micromachining, with huge economic and social benefits
