selects high quality ceramic fine powder and micropowder as materials, adopts modern advanced molding technology to produce a multitude of ceramic tubes, rods, beads, balls, columns, plates, films and other forms. These ceramic products sintered in high temperature have a large elastic modulus, high mechanical strength, high oxidation resistance at elevated temperature, excellent thermal conductivity, good electrical insulation, high electric strength, low dielectric loss, stability of electric properties with temperature and frequency variation, high wear-resistance, good corrosion resistance, superior waterproof under temperature mutation and surface machinability, which are widely used in electronics, electrical appliances, machinery, petroleum, chemical, medical, textile, automobile, metallurgy and aerospace industries and so on. Many of alumina's extinguished properties could be strengthened through variation in manufacturing methods and in chemistry.
