Alumina block ceramics have the characteristics of high hardness, wear resistance and corrosion resistance. They are formed by dry pressing, grouting, hot pressing and static pressing, which help to eliminate microscopic pores and are widely used in mechanical seals. , Ball milling media, cutting tools, ceramic bearings, automotive engine parts, paper machine dehydration equipment, etc.

The preparation process of alumina ceramics is essentially a densification process that safely excludes microscopic pores during the sintering process. The size, quantity, and type of pores in the material will have a significant impact on its transparency. In addition to the porosity, the diameter of the pores also has a great influence on the light transmittance of alumina ceramics. Alumina ceramics have excellent mechanical strength, high temperature resistance, wear resistance, corrosion resistance, good insulation performance and durability. Alumina wear-resistant ceramics are made of 92 alumina powder or 95 alumina powder and sintering aids, granulated by a granulator, and then dry-pressed into blocks under a dry press and supporting molds, and fired in a high-temperature kiln at 1700 degrees Made of white corundum wear-resistant ceramics. It is mainly used in industrial equipment to protect the equipment from wear, so as to achieve a longer service life of the equipment and reduce the loss caused by downtime maintenance.

Alumina ceramics have good electrical conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics are ceramics with a wide range of uses. Due to its superior performance, it has been more and more widely used in modern society to meet the needs of daily use and special performance.

What are the advantages of alumina ceramics
 : 1. High hardness of alumina ceramics: determined by the Shanghai Institute of Ceramics, Chinese Academy of Sciences, its Rockwell hardness is HRA80-90, second only to diamond, and its wear resistance far exceeds wear-resistant steel and stainless steel . 
2. Alumina ceramics have very good wear resistance: measured by the Powder Metallurgy Institute of Central South University, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to the follow-up survey of our customers for more than ten years, under the same working conditions, the service life of dispensing ceramic equipment can be extended by at least ten times. 
3. Alumina ceramics are light in weight: the density of alumina electronic ceramics is 3.5g/cm3, which is only half that of steel, which can greatly reduce the load on equipment.
