In a pioneering move, Engineering Ceramic proudly unveils its latest innovation – Zirconia Balls, showcasing the company's dedication to pushing the boundaries of ceramic technology.
Normally, Alumina Oxide ceramic balls is used at temperatures up to 1850 ºC. It’s extremely hard, resistant to abrasion, and immune to all furnace atmospheres. Alumina Oxide ceramic balls applications is include chemical pumps, down-hole pumps, valves, gages, flowmeters, etc.
Boron carbide is a versatile material widely used in various industries including defense, aerospace and manufacturing. It has excellent mechanical properties, high temperature resistance and exceptional hardness, making it an ideal material for applications requiring wear and tear resistance.
Boron carbide (B4C) is gray-black and is a very hard artificial material. Its Mohs hardness is 9.3 and its microhardness is 5500~6700kg/mm2, second only to diamond and cubic boron nitride. The crystal structure of boron carbide is hexagonal crystal. Density is 2.52g/cm3. The melting point is 2450°C. When the temperature is higher than 2800°C, it decomposes and volatilizes rapidly. Its linear expansion coefficient is 4.5×10-6/℃ (20~1000℃), its thermal conductivity is 121.42 (100℃) W (m·K), 62.80 (700℃) W/(m·K), and its resistivity It is 0.44 (20℃)Ω·cm and 0.02 (500℃)Ω·cm.
