Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, which is used in thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a kind of ceramics with a wide range of uses. Because of its superior performance, it has been widely used in modern society and meets the needs of daily use and special properties.
Alumina ceramics is a ceramic material with α-Al2O3 as the main crystal phase. It is an early developed high-temperature structural ceramic material, and its Al2O3 content is generally between 75 and 99.9%. It is usually customary to classify by the content of Al2O3 in the ingredients. The Al2O3 content of about 75% is “75 porcelain”, the content of 85% is “85 porcelain”, the content of 95% is “95 porcelain”, and the content of 99% is “99 porcelain”.
According to market research: Alumina, one of the important raw materials for the production of ceramic tiles, remains in a stable range even when the market situation in the ceramic industry is generally sluggish and the prices of many ceramic chemical raw materials are rising indefinitely. , rarely affected by the downturn in the ceramic industry, it can be seen that the role of alumina in ceramics is indispensable. Therefore, alumina ceramics came into being in the ceramic industry-alumina ceramics is a ceramic material with Al₂O₃ as the main raw material and corundum as the main crystal phase. Because of its high mechanical strength, high hardness, high frequency dielectric It has the advantages of small loss, high insulation resistance at high temperature, chemical corrosion resistance and good thermal conductivity.
