Features:
Its primary crystal is very small. It has good filling property and sintering activity. Aqueous slurry has good thixotropic fluidity. It can improve the sintered density, flexural and compressive strength of castables at high temperature. It can also enhance the castbles¡¡¥ resistance to abrasion, corrosion and erosion.
Applications:
It can be used in castables of low cement, ultra low cement or no cement and shaped or unshaped refractory materials, etc
Main technical parameters for tm-nb series superfine activated alpha-alumina special for refractory castable:
Features: It has characters of narrow particle size distribution, high grinding efficiency and good polishing effect. Its grinding efficiency is much better than soft abrasives, like silica. Because of its good particle shape, high smoothness after surface treatment and better polishing effect than white fused alumina, it is widely used to polish aluminum product, steel product, stainless steel, stone, glass, wall and floor tiles, etc. Since it entered the market, it has got praise from the users. It shows its great polishing performance especially in the field of metallic materials, like stainless steel,
Features: This series is a new ultrafine powder. Its crystal size is even smaller (0.5~1um). It can be easily ground to about 1um average sizes of micro powder. It has a narrow range of powder particle size distribution and a good dispersion. Applications: It can be used in knife tools, precision alumina ceramics and all kinds of ceramic tools produced in the way of isostatic
Features: Primary crystal has good sphericity. It can be easily sintered. It also has characters of fine grain size, high purity, good grindability, narrow particle size distribution, good dispersion and high porcelain density. Our company developed this kind of powder for electronic substrate tape casting. For example d23:96 porcelain, its porcelain density can reach to
