Alumina Ceramic
Alumina ceramic is a kind of material based on alumina (Al2O3), which is used in thick film integrated circuit. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It needs to be noted that ultrasonic cleaning is needed.Because of its superior performance, it has been widely used in modern society, meeting the needs of daily use and special performance.
The applications for alumina advanced ceramics are heavy-duty forming tools, substrates and resistor cores in the electronics industry, tiles for wear protection and ballistics, thread guides in textile engineering, seal and regulator discs for valves, heat-sinks for lighting systems, protection tubes in thermal processes or catalyst carriers for the chemicals industry.
Features & Advantages
1. High hardness.
2. High heat resistance: alumina ceramic has excellent thermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.
4. High electrical resistivity: alumina is an electrically insulating material.
5. High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
