black silicon carbide for refractory crubile
Black silicon carbide (SiC) is a synthetic abrasive material produced by reacting silica sand and petroleum coke in an electric resistance furnace at high temperatures (around 2200°C). It is one of the hardest synthetic abrasives, with a Mohs hardness of 9–9.5, second only to diamond and boron carbide. Key Properties of Black Silicon Carbide: Hardness: Extremely hard …
what is brown fused alumina/BFA/A
Brown Fused Alumina (BFA) is an artifical abrasive and refractory material, mainly composed of aluminum oxide (Al₂O₃), usually containing a small amount of other oxide impurities (such as iron oxide, silicon oxide, etc.). It is made by high-temperature smelting of bauxite (mainly aluminum oxide) and other raw materials, and is named for its brown color. …
Black Silicon Carbide Micropowder
Silicon Carbide is produced by a process involving the electrochemical reaction of silica(SiO2)-in the form of quartz mixed with Carbon(C) in the form of raw petroleum coke. The stoichiometric mixture is reacted in an electrical resistance furnace at a temperature up to 2500 centigrade to yield high-quality crystals. The process is large furnace technology with …

Resin coated sand as moulding sand of casting precoated sand
Fused ceramic sand, also called as ceramic Foundry Sand, is kind of man-made spherical shape ceramic particles featured by high refractoriness, low thermal expansion made by spraying melted from the fused bauxite. It provides a simple and efficient way in the foundry industry to improving the quality of the castings, reducing the production cost and avoiding environmental pollution so it is much better than silica sand. And it is also good substitution to Chromite sand and Zircon sand because of its lower price. At the present, Ceramic sand is acknowledged in the worldwide as the newest and the best ideal sand for the foundries and has a very wide feasibility of applications for the future development.
Steel foundry industrial filler materials Chromite sand Chrome foundry sand
Foundry chromite sand is a natural process products of chromite through the broken screen classification, chrome ore, its main chemical composition of cr2o3, this kind of sand heated volume stability, high thermal conductivity, when in contact information with the molten metal, not only has good resistance to basic slag, not with ferric oxide and other chemical reactions, and itself has the characteristics of the solid phase sintering, can be a very good prevent the infiltration of molten metal, avoid to touch sand defects, suitable for all kinds of stainless steel, alloy steel and carbon steel gradually shape the original sand core and coating.
China sandblasting White fused alumina price
White fused alumina is a white abrasive made from industrial alumina powder (Al2O3) with a content of over 98% and a small amount of iron oxide and silicon oxide. It is a white abrasive which is melted at high temperature. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It is made by smelting and cooling above 2000 degrees in arc, grinding and shaping, removing iron by magnetic separation, and sieving into many kinds of granularity. It is compact in texture, high in hardness and sharp in shape.
