天然噴砂磨料金剛砂   耐磨金剛砂

性質 

　　天然噴砂磨料金剛砂   耐磨金剛砂硬度很大，耐高溫，高溫時能抗氧化。

用途 

　　（1）作為磨料，可用來做磨具，如砂輪、油石、磨頭、砂瓦類等。

　　（2）作為冶金脫氧劑和耐高溫材料。

　　（3）還可以做五金，玻璃，寶石，玉器等拋光研磨。

　　碳化矽主要有四大應用領域,即:功能陶瓷、高級耐火材料、磨料及冶金原料。目前碳化矽粗料已能大量供應,不能算高新技術產品,而技術含量極高的納米級碳化矽粉體的應用短時間不可能形成規模經濟。

　　（４）高純度的單晶，可用於制造半導體、制造碳化矽纖維。

With bauxite, carbon material, iron filings as raw materials, Brown Fused Alumina is restored and obtained through the melting of the brown the brownartificial corundumin the furnace above 2200℃, and made of a variety of particle sizes products by purifying, crystallization, sorting, crushing, magnetic separation and screening methods. With its dense texture, high hardness and the formation of spherical particles, it issuitable for the manufacture of ceramics and resin, as well as the high-Bonded Abrasives grinding, polishing, sand blasting, precision casting and so on, also can be used to manufacture high-grade refractory material.

Brown Fused Alumina has high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant and other characteristics. Dozens of refractory manufacturers have proved in practice that the product has not detonate, non-powder, non-cracking characteristics in the application process.

Particle size is in accordance with international standards and can be processed as requirements. Universal size: No. F4 ~ F320, its chemical composition varies depending on grain size. Its prominent feature is the small crystal size, impact resistance and spherical particles. This product has high purity, dense texture, large bulk density, strong self-sharpening, good toughness, low level magnetic material content and other characteristics.
