Purity 99% Porous Heater Alumina Ceramic Tube
99% Alumina Ceramic TUBE
1. Alumina ceramic
With the development and production of ceramic, roller kiln is widely used in building sanitary ceramics, daily porcelain and specialty ceramics. The requirements of refractory material used in furnace are continuous improvement, especially for strength and high temperature mechanical properties of roller presented updated requirements.
Alumina ceramic is the development trend for ceramic , because they fully meet the various needs of ceramic tile production, with the other advantages which other ceramic roller cannot be of.
These precision toleranced ceramic components or assemblies are used in a wide range of semiconductor, electronic, electrical, mechanical, chemical, automotive, textile and the other industrial engineering applications, due to their extreme hardness, more resistances to wear, heat,corrosion, high electric insulation, and low thermal expansion.
From life-extending elements to next-generation, renewable energy products, Jiangsu Province Ceramics Research Institute Co., Ltd genuinely helps make the world measurably better. We work with engineers and designers like you to develop tomorrow’s technology and art for just what you search for in the global economy.
