Henan Superior Abrasives - High Quality Silicon Carbide and Silica Fume Supplier

  Densified micro-silica fume , also known as DMS or densified silica fume, is a highly reactive pozzolanic material used in concrete and other construction applications. It is produced by treating undensified silica fume to increase its mass density up to a maximum of 400-720 kg/m. What is densified micro-silica fume? Densified micro-silica fume is a waste product created during the production of silicon and ferrosilicon alloys. It is composed of extremely fine particles of silica that have been densified, or compacted, together to form agglomerates. The resulting material has a much higher density than undensified micro-silica fume, and is used in a variety of applications where its high density and strength are advantageous. Densified micro-silica fume is often used as a replacement for Portland cement in concrete, where it improves the compressive strength and durability of the finished product. It is also used in the manufacture of refractory bricks and castables, where its hi...

Green silicon carbide grinding powder Carborundum powder F600 F800 Green silicon carbide powder is a very hard abrasive material with uniform particle size distribution. The hardness of it only ranks after diamond and B4C, and it is harder than black silicon carbide. So it is suitable to grinding large range of hard material such as titanium alloy, marble, carbide alloy, optical glasses, ceramics, etc. On the other hand, green silicon carbide has extraordinary features such as high chemical stability, low thermal expansion rate, it is suitable for heat resistance & corrosion resistance coatings, paints, and other construction products. Typical physical properties of Green silicon carbide grinding powder Carborundum powder F600 F800 Mohs Hardness: 9.5 Vickers Hardness: 3100-3400kg/mm2 Specific Gravity: 3.2g/cm3 Bulk density(LPD): 1.2-1.6 g/cm3 Color: Green Particle shape: Hexagonal Melting Point: Dissociated at about 2600 centigrade Maximum service temperature: 1900 cent...
