What is 95 alumina ceramic

---

95% alumina ceramic, as the name suggests, refers to ceramic materials with an alumina (Al ₂ O3) content of 95%. This high-performance ceramic material has been widely used in many industrial fields due to its unique physical and chemical properties.

95 alumina ceramic is a ceramic material mainly composed of alumina, with an alumina content of up to 95%. The remaining 5% may include other components such as combustion aids and additives, which play a key role in the manufacturing process and help improve the formability, sintering performance, and final physical properties of ceramics.

Main characteristics
High hardness and wear resistance: The Rockwell hardness of 95 alumina ceramic is as high as 85, which gives it excellent wear resistance and is suitable for occasions that require high wear resistance.
High temperature resistance: This ceramic material can withstand high temperature environments and is suitable for use at high temperatures. The high-temperature sintering process tightly binds its particles, further enhancing its high temperature resistance performance.
Good corrosion resistance: 95 alumina ceramics can resist various chemical corrosion and are suitable for occasions that require corrosion resistance.
Excellent insulation performance: It has good insulation performance and electrical strength, suitable for occasions that require insulation.
High mechanical strength: It has high mechanical strength and can withstand large mechanical stresses.

Production process
The production process of 95 alumina ceramics includes multiple steps such as raw material preparation, mold preparation, blank forming, drying, sintering, finishing, surface treatment, and inspection packaging. Among them, sintering is one of the key steps, usually using high-temperature sintering method to make the particles of the green body more tightly bound, thereby obtaining excellent physical and chemical properties.

Application area
Industrial grinding media: 95 alumina ceramics are widely used as grinding media in mills such as ball mills, vibration mills, planetary mills, and agitator mills due to their high hardness and wear resistance.
Electronic components: In the fields of radio, electronic components, and new energy, 95 alumina ceramics are widely used due to their excellent insulation performance and high temperature resistance.
Textile ceramics: In the textile industry, 95 alumina ceramics can be used to make ceramic accessories such as ceramic shaft sleeves and ceramic plungers.
Building and sanitary porcelain industry: In the building and sanitary porcelain industry and deep processing of non-metallic mineral products, 95 alumina ceramic grinding balls can be used to grind ceramic color glaze materials, improve the fineness and grinding efficiency of color glaze materials.

95 alumina ceramic is a high-performance ceramic material with excellent properties, which has been widely used in many industrial fields. With the advancement of technology and the development of industry, its market prospects will become even broader.
