Application
Alumina Ceramic is a high-grade ceramic material that is ideal for laboratory applications. It is well balanced and physically stable. In addition, this fine ceramic offers exceptional chemical and corrosion resistance, high hardness, strength, and durability, superb wear resistance and high resistance to alkalies and other fluxes.Best roast container for making powder TV, rare earth materials, precious metals, and roasting high, medium and low ceramic capacitors, NTC, PTC piezoelectric ceramic and lithium cobalt oxide, lithium manganese oxide powder.
Advantage
-Hard, wear-resistant
-Excellent dielectric properties from DC to GHz frequencies
-Resists strong acid and alkali attack at elevated temperatures
-Excellent size and shape capability
-High strength and stiffness
-High thermal shock resistance
