With good comprehensive properties, alumina (Al2O3) ceramics are used widely and well. Alumina (Al2O3) ceramics are rich in raw materials, low in price, high in strength and hardness, resistant to thermal shock, good in insulation, chemical stability, and adhesion to metals. At present, Al2O3 is the main material of ceramic plate. According to Material Institute of Stanford University, the Rockwell hardness of aluminum oxide (Al2O3) ceramics is HRA80-90, which is is only second to diamond and superior to the wear-resistant steel and stainless steel in terms of wear resistance. The wear resistance of alumina (Al2O3) ceramics 266 times higher than the manganese steel and 171.5 times higher than high-chromium cast iron. The density of alumina (Al2O3) ceramic is 3.5g/cm3, only half of that of steel, which can greatly reduce the load for the equipment.
According to "European alumina ceramic market forecast by 2027 – COVID-19 impact and analysis – by application (electronics and semiconductors, energy and power, military and national defense, automotive, industrial, medical, etc.)" from "Insight Partners", it is estimated that the alumina ceramic market will grow from 9.1 billion dollars in 2019 to 11.3 million dollars by 2027 and it is predicted that from 2020 to 2027 it will grow at a compound annual growth rate of 3.2%.
Able to meet the performance requirements of high-end chips, ceramic plate has been well applied in high-end products in the fields of home appliance lighting, information communication, sensors, etc. It is an ideal packaging material for the large-scale integrated circuits and electronic modules. The use of ceramic plates provides power for the electronic and semiconductor industries.
Ensure the automotive sensors by the reliable performance
The sensors in the automobile are in a harsh environment (high temperature, low temperature, vibration, acceleration, humidity, noise, exhaust gas) for a long time. They are required to be small and light, have good re-usability, and have a wide output range. However, ceramics can protect chips from corrosion even in the harsh environment by their natures of high temperature resistance, vibration resistance, moisture resistance and chemical corrosion resistance. Practically and reliably speaking, ceramic plates can bring considerable improvement to products. There is no doubt that ceramic plate is the guarantee for product’s cost performance.
Ceramic plate is likely to develop to be in higher density, higher precision and better reliability, which is the general trend. It is a more feasible choice for the development of electronic packaging materials in the future.
