What is the difference in performance between alumina ceramics and silicon nitride ceramics?
The first is alumina ceramics, because alumina ceramics have good mechanical strength, conductivity and high temperature resistance. However, when cleaning alumina ceramics, you must choose the ultrasonic cleaning method, and alumina ceramics actually belong to The most widely used ceramic is mainly because of its superior performance, and its application in the current market is becoming more and more extensive. It can not only effectively meet the daily use, but also meet some special needs.
The second is silicon nitride ceramics. In fact, silicon nitride is very high in strength, especially silicon nitride after heat treatment. It can be said that it is the hardest substance in the world, and silicon nitride ceramics are very resistant to high temperatures. , The entire strength can continue at a high temperature of 1200 degrees Celsius, and there will be basically no signs of decline. Even after being heated, it will not directly melt into a melt, and it will not be decomposed until it reaches about 1900 degrees Celsius. The corrosion resistance of silicon ceramics is also very amazing. Basically, it can withstand all organic acids and caustic soda solutions below 30%. It can also resist corrosion by more organic acids. Therefore, silicon nitride ceramics are high-performance electrical insulating materials.
