The introduction of ceramic substrate products has opened up the development of heat dissipation application industry. Due to the heat dissipation characteristics of ceramic substrates, ceramic substrates have the advantages of high heat dissipation, low thermal resistance, long life and voltage resistance. With the improvement of production technology and equipment, the product price is accelerated and rationalized. In order to expand the application areas of the LED industry, such as the indicator lights of home appliances, car lights, street lights and outdoor large billboards. The successful development of ceramic substrates will become a service for indoor lighting and outdoor lighting products, making the LED industry a broader market in the future.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
