Product Details
The calcined aluminum powder is calcined from industrial aluminum hydroxide or industrial aluminum oxide, calcined into crystal type stable α-type aluminum oxide product at appropriate temperature, and the aluminum oxide micro powder made from calcined α-type aluminum oxide as raw material。
Calcined alumina powder products have high melting points, excellent mechanical strength, hardness, high resistivity, and thermal conductivity. It can be widely used in electronic equipment, structural ceramics, refractory materials, wear-resistant materials, polishing materials and other industries.
According to different physical and chemical indexes, calcined alumina powder products are mainly divided into five categories: boron fluorine (BF2:1), boron fluorine (BF5:1), pure fluorine (F), pure boron (B) and no mineralization agent, including boron chlorine (BL) and FL); special alumina products are divided into 325 items, 500,600,600800 micro powder and fine crystal micro powder.
According to different use needs, formed dry pressure, isostatic pressure process series, hot pressure casting, grouting molding series, refractory series, casting series, aluminum structure ceramic granulation powder and other five series of products.
The dry pressure and isostatic pressure process series
The series is refined by advanced formula and strict process, with reasonable grain size distribution, good particle mobility, loose grain bonding, good abrasiability and easy sintering. Its porcelain parts compact, clean surface finish, high mechanical strength, high electric insulation, is the ideal raw material for manufacturing special ceramics.
Hot die-cast, grouting molding series
This series of products has large original grain size, stable performance, good molding performance, small shrinkage rate, wide range of use, especially applicable for hot die casting, grouting molding series, can be used for various high temperature resistant porcelain parts (spark plug, etc.), wear-resistant porcelain parts (mortar pump axion pump liner, impeller, grinding medium ball, etc.), electronic substrate, electronic vacuum pipe, etc.
Refractory materials series
This product is stable crystal type, can improve the fire resistance, improve mechanical performance, suitable for the production of irregular refractory materials (various high aluminum castings), finalized refractory materials (corundum brick, etc.), furnace materials, to meet the customer requirements for high temperature, excellent thermal shock stability and processing characteristics, and prolong the service life of refractory materials.
Past the design series
This product has uniform grain, has good filling performance and pouring activity, which can improve the sintering density, high temperature folding resistance and pressure resistance strength, and enhance the abrasion resistance, corrosion resistance and erosion resistance performance of pouring materials. Can be used for low cement, ultra-low cement or no cement pouring materials, shaping refractory materials and precision polishing, etc.
Aluminum oxide ceramic granular powder
After scientific research ingredients, automatic grinding, pulp making, spray and drying. Fine particle size distribution, good mobility and moderate strength, high billet strength, excellent stripping performance and low firing temperature; the product has smooth surface and dense structure. It can meet the process needs of precision ceramic rapid dry pressure forming, and is the ideal raw material for producing electronic ceramic and structural ceramic components.
