Alumina ceramic is an alumina (Al2O3) as the main material for thick-film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and temperature resistance. Should be noted that the required ultrasonic washing. Alumina ceramic is a widely used ceramic. Application in modern society has been more widely because of its superior performance to meet the needs of daily and special features.In order to enhance the Alumina ceramic, significantly increase the mechanical strength and abroad, new push to an alumina ceramic strengthening process. The process is novel, the technical means adopted by the alumina ceramic surface using electron beam vacuum coating, sputtering vacuum coating or chemical vapor deposition method, coated with a layer of silicon compound film in 1200 ℃ ~ 1580 ℃ heat treatment, the Alumina ceramic steel. Enhanced mechanical strength of alumina ceramic can be a substantial increase in the original basis, with ultra-high strength Alumina ceramic.
It has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. And it is also used to produce high-temperature crucibles, resistant stove pipe and special wear-resistant materials,such as ceramic bearings, ceramic seals and valve films,etc.Alumina ceramics is used as a corrosion-resistant, wear-resistant parts.
