Alumina ceramics have the properties of high temperature resistance


Alumina ceramic parts with high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetic insulation, oil-free self-lubrication, high speed and other characteristics.Can be used in extremely harsh environment and special working conditions, can be widely used in aviation, aerospace, navigation, petroleum, chemical, automobile, metallurgy, electric power, textile, pump, medical equipment, scientific research and national defense and other fields, is the new material application of high-tech products.


High speed bearings of alumina ceramic parts: with cold resistance, small mechanical elasticity, pressure resistance, poor thermal conductivity, light weight, small friction coefficient and other advantages, can be used in 12000 RPM ~75000 RPM high speed spindle and other high-precision equipment.


Alumina ceramic parts is a kind of high temperature bearing: the material itself has high temperature resistance of 1200℃, and self-lubrication is good, the use of temperature between 100℃-800℃ does not produce due to temperature difference caused by expansion.Can be used in plastic, steel and other high temperature equipment.


Corrosion resistant bearings: the material itself has the characteristics of corrosion resistance, can be used in strong acid, strong alkali, inorganic, organic salt, sea water and other fields, such as: chemical machinery, shipbuilding, medical equipment and so on.


The electric furnace is the most widely used heating device for the firing of alumina ceramic parts.In addition to atmospheric pressure sintering (no pressure sintering), there are hot pressing sintering and hot isostatic pressing sintering.Although continuous hot pressing sintering increases production, the cost of equipment and molds is too high. In addition, the length of products is limited due to axial heating.The hot isostatic pressing sintering adopts high temperature and high pressure gas as the pressure transfer medium, which has the advantage of uniform heating in all directions, and is very suitable for the sintering of products with complex shape.
