Corundum mullite bearing board can be of various size requirements for zirconia, alumina, mullite cordierite.Corundum products.
The product is in a high temperature environment and not burning products react, the highest use temperature up to1700 ℃, itself: not easy to deformation and cracking, long service life, etc..
All products are widely used in electronic components, magnetic material, powder metallurgy industry. Products: 1alumina setter plate 2 zirconia setter plate 3 mullite cordierite bearing firing plate 4 burning bearing plate 5 corundumbearing board 6 mullite - cordierite bearing board 7 zirconium, zirconium plate column, V type slot. Alumina zirconiashaped refractory products.
Product introduction: ceramic burning plate is made of fused zirconia, a special refractory alumina as raw materials,high temperature sintering, with excellent chemical resistance properties and high-temperature resistance. It cantolerate a variety of metal oxide / metal oxide solution of non erosion, high strength, excellent thermal shock resistance, widely used in the ceramic capacitor, sensitive components, magnetic materials, chip inductors and other electronic components industry.
A variety of square, circular and strip shaped flat, high strength with high and excellent thermal stability.
