Advantages of Alumina Ceramic
High mechanical strength
The flexural strength of alumina ceramics can reach 250MPa, and the flexural strength of hot-pressed alumina ceramics can reach 500MPa, and their mechanical strength can still be maintained at a temperature of 900 °C;
High resistivity
Good electrical insulation performance, room temperature resistivity 1015Ω·cm, dielectric strength 15kV/mm;
High hardness
The hardness of alumina ceramics is 9 on the Mohs scale and the Rockwell hardness is HRA80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel, which is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. Under the same working conditions, the service life of the equipment can be extended by at least ten times;
High melting point
Corrosion resistance, melting point 2050 °C, can resist the erosion of molten metals such as beryllium, strontium, nickel, aluminum, vanadium, tantalum, manganese, iron, cobalt, etc., and also has strong resistance to the erosion of NaOH, glass and slag;
Chemical stability
It does not react with many complex sulfides, such as phosphide, arsenide, chloride, nitride, bromide, iodide, oxide, sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, etc.
Applications of Alumina Ceramic
Electronic devices
As an insulating material under high temperature and high pressure, alumina ceramics are widely used in the electronics industry.
Wear-resistant material
It can withstand wear under extreme conditions, so it is often used in the manufacture of metal liquid stirring rods, engineering wear-resistant parts, etc.
High-temperature devices
Such as high-temperature metal delivery tubes and high-temperature thermocouple tubes, alumina ceramics have demonstrated their high temperature resistance in these applications.
Mechanical parts
Including cutting and grinding tools and wear-resistant porcelain parts for textile machines. The high strength of alumina ceramics makes it ideal for these areas.
Bioceramics
In the medical field, alumina ceramics can be used to make biocompatible medical devices such as artificial joints and teeth.
