? ? 金剛砂是由粘土中的二氧化硅與碳在高溫下反應生成。金剛砂還包括棕剛玉，黑剛玉，白剛玉，碳化硅。
????金剛砂硬度僅次于金剛石、碳化硼和立方氮化硼，在無機材料中排行第四。目前已能通過熱壓燒結法制得高致密度的碳化硅。它具有很高的強度及良好的抗氧化性能，在高溫下不變形，可作為高溫燃氣輪機上的渦輪葉片，也可作耐磨的密封材料，還可作火箭尾噴管的噴嘴及輕質的用品等。金剛砂在噴磨過程中，能深入到表面的洞穴和凹坑處，到達金屬的裸表面，因此它能徹底地除去所有的鐵銹，溶水性鹽類物質和其他污染物，經過處理的金屬表面非常干凈，無嵌入物。
????金剛砂是一種天然的無毒礦物，內部不含有毒的重金屬或放射性污染物，在操作過程中，由于產品比重比較大，很少會產生粉塵，有效地保證了操作員的健康。
????金剛砂非常適用于多種領域，常規情況下，它能被重復使用5次，如果5次過后還沒有失去它的切割能力，循環次數可以更多，在沒有切割能力后，金剛砂還可以回收應用到建筑行業，作為水泥添加料，無須更換現有的噴砂裝置，價位適中，性價比高。

The diamond sand is formed by the reaction of silica and carbon in clay at high temperature. Corundum also includes brown corundum, black corundum, white corundum, silicon carbide.
Diamond hardness is second only to diamond, boron carbide and cubic boron nitride, and is ranked fourth in the inorganic materials. High density silicon carbide has been produced by hot press sintering process at present. It has antioxidant properties of high strength and good, no deformation at high temperature, as the temperature of the gas turbine turbine blade, also can make wear-resisting sealing material, nozzle and light can be used as rocket nozzle bulletproof products etc Emery grinding in the spraying process, can go deep into the caves and pits on the surface, to the bare metal surface, so it can completely remove all rust, water soluble salts and other pollutants, after surface treatment of metal is very clean, no insert.
Emery is a non-toxic natural mineral, not containing heavy metals or toxic radioactive pollutants, in the operation process, because the proportion of relatively large, rarely produce dust, effectively ensure the health of the operator.
Emery is very suitable for a variety of areas, under normal circumstances, it can be reused for 5 times, 5 times after if has not lost its cutting capacity, cycle times can be more, in the absence of cutting ability, emery can also be applied to the recovery of the construction industry, used as cement additives, without replacing the existing sand blasting device. The moderate price, high price.

Transport and handling: in the transport process, not drag hook, should prevent mixed with the solid material, strong vibration, friction, hit, hit, forbid throwing should be lightly armed light discharge, to reduce the breakage of packing, the impact of the use.
Storage: should be stored in a cool and dry place, to prevent internal and external packaging bag break, prevent moisture and adsorption of other substances in the air, affect the use effect. It is strictly prohibited to mix with poisonous and harmful gas or volatile matter, and keep away from the source of pollution.
