Alumina ceramic wafer processing process

Abstract

An alumina ceramic wafer processing process includes the following steps that firstly, distilled water is used for cleaning, wherein a ceramic wafer is placed in 100% pure water to be cleaned and then is dried; secondly, ketone washing is performed, wherein the cleaned ceramic wafer is placed in 10-20% acetone to be soaked and then is dried; thirdly, alkaline cleaning is performed, wherein the ceramic wafer washed in acetone is placed in a 80-90% sodium carbonate solution to be soaked and then is dried; fourthly, acid pickling is performed, wherein the ceramic wafer dried in the third step is placed in a 8-12% sulfuric acid solution to be soaked and then is dried. The alumina ceramic wafer processing process has the advantages that hardness is large, abrasion resistance is excellent, weight is low, surface adsorption capacity is high, the surface adsorption capacity of the processed ceramic wafer is 10-20 times that of a non-processed ceramic wafer, and the processed ceramic wafer is quite firm and durable after being combined with rubber through glue.

Description

technical field [0001] The invention relates to the technical field of alumina ceramic sheet processing, in particular to an alumina ceramic sheet processing process. Background technique [0002] Alumina ceramics: high alumina content, relatively dense structure, and special properties, so it is called special ceramics. Al2O3. The ceramic material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions fill two-thirds of the octahedral gaps. This is the same stable α-Al2O3 structure as natural corundum, so the ceramic has a high melting point and high Hardness, with excellent wear resistance. The hardness of the ceramic patch is ≥ HRA85, second only to the hardness of diamond, and the surface is smooth, the friction coefficient is small, and the wear resistance is very ideal, especially in the high temperature oxidizing medium or corrosive medium, the material of the ceramic patch has better performance than other metal materials. It is much super...

AI Technical Summary

Problems solved by technology

The hardness of the ceramic patch is ≥ HRA85, second only to the hardness of diamond, and the surface is smooth, the friction coefficient is small, and the wear resistance is very ideal, especially in the high temperature oxidizing medium or corrosive medium, the material of the ceramic patch has better performance than other metal materials. It is much superior. Ordinary ceramic sheets and rubber cannot be bonded together. After using glue, the bond is not firm, and the ceramic sheets need to be processed.
