Alumina Ceramic Stick
My factory looking for distributors
Alumina ceramic stick have a wide range of applications, involving high-temperature testing and analysis equipment in various industries, such as coal testing and analysis equipment, metallurgical powder testing and analysis equipment, and chemical and glass industry testing and analysis equipment.
The Mohs hardness of alumina material is 9, second only to some materials such as diamond, and the ceramics produced have better hardness and strength. Compared with the common steel structural parts, the ceramic structural parts made of the ceramic structural parts are also a qualitative leap in wear resistance, and the wear resistance is tens, hundreds, thousands of times higher than that of the steel structural parts; Alumina ceramics have good stability and high melting point. Alpha alumina does not react with strong acid and alkali, and its melting point is as high as 2054 degrees Celsius.

RFQ
1.What is alumina ceramic used for?
Because of their excellent chemical stability, alumina ceramics are used widely in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves. Aluminum oxide ceramics are used in the manufacture of textile wear parts and knives. This is due to their extreme hardness and wear resistance.
2.Is alumina ceramic safe?
Alumina ceramic, composed mainly of aluminum oxide (Al2O3), is widely regarded as safe for various applications due to its biocompatibility, thermal resistance, and electrical insulation properties. Used in medical implants and dental applications, it is well-tolerated by the body.
3.What is the difference between ceramic and alumina?
Ceramics are non-metallic, inorganic materials that are typically composed of a combination of metallic and non-metallic elements. Alumina is a type of ceramic oxide, specifically an oxide of aluminum. It is widely used in various applications due to its excellent mechanical, thermal, and electrical properties.
4.Is alumina ceramic brittle?
Alumina ceramic is often used in armour systems. This material is known to have a brittle response under tensile loading, while a ductile response is found when sufficiently high pressures are reached.
