99% alumina ceramic plate

ceramic flange plate is a high-performance component made from advanced ceramic materials, such as alumina (Al₂O₃), zirconia (ZrO₂). It is designed to connect, seal, or support pipelines, valves, pumps, and mechanical equipment under extreme working conditions.   Compared with metal flanges, ceramic flange plates offer excellent corrosion resistance, high temperature resistance, wear resistance, and electrical insulation. They maintain stable performance in harsh environments involving acids, alkalis, high heat, and abrasive media.     Key features include: • High hardness and low wear rate • Excellent chemical stability • Good thermal shock resistance • High mechanical strength and long service life • Lightweight and non-magnetic

The heat resistance corrosion resistant 99% alumina ceramic plate is a high - performance ceramic material plate. Here are its main characteristics: • High - temperature resistance: It can work stably at high temperatures. Its melting point is as high as 2075℃, and it can be used for a long time below 1700℃ . The low thermal expansion coefficient ensures that it will not deform or soften easily at high temperatures . • Corrosion resistance: It has extremely strong chemical stability and is highly resistant to acid, alkali, and organic solvents . For example, it can be immersed in 98% concentrated sulfuric acid for half a year without being corroded . • High hardness and wear resistance: The Mohs hardness of 99% alumina ceramic can reach level 9 or higher . Its wear - resistance is 10 to 20 times that of stainless steel, which can effectively resist mechanical wear and scratching . • Good electrical insulation: It has a high volume resistivity and dielectric strength, with a volume resistivity of ≥10¹⁴Ω・cm and a breakdown strength of ≥25kV/mm . It can be used as an ideal insulating material in electronic equipment. These properties make 99% alumina ceramic plates widely used in semiconductor manufacturing, electronic industry, chemical industry, aerospace and other fields . The heat - resistance corrosion - resistant 99% alumina ceramic plate is a high - performance ceramic product with the following notable features: • High - temperature resistance: It has a high melting point of approximately 2050℃ and can be used for a long time at temperatures below 1700℃ . Its low thermal expansion coefficient ensures that it maintains good dimensional stability at high temperatures without deforming or softening easily . • Corrosion resistance: With strong chemical stability, it is highly resistant to acids, alkalis, and organic solvents . It hardly reacts with common strong acids such as hydrochloric acid, sulfuric acid, and nitric acid, as well as strong bases like sodium hydroxide . Only hydrofluoric acid and concentrated alkalis at high temperatures can corrode it . • High hardness and wear resistance: The Mohs hardness of 99% alumina ceramic can reach level 9 or higher . Its surface is dense, and its wear - resistance is much better than that of low - purity alumina ceramics . • Good electrical insulation: It has a high volume resistivity of ≥10¹⁴Ω・cm and a breakdown strength of ≥25kV/mm . It can maintain stable insulation performance in high - voltage and high - frequency environments .

99% alumina ceramic valve plate is a critical functional component in fluid control valves, where the core plate structure is fabricated from 99% high-purity alumina ceramic (Al₂O₃ content ≥99%, with trace impurities such as SiO₂, MgO, and CaO accounting for the remaining 1%).
