TAOANG Industrial is headquartered in Zhengzhou, Henan Province. The factory is located in Henan Sanmenxia corundum Industrial Park. In 2007, the partners jointly built the Sanmenxia Xinfeng Abrasives Factory, which is mainly engaged in producing and processing brown fused alumina. In 2018, Taoang Industry continued to make a white fused alumina factory in Zhaigen Industrial Park, Sanmenxia City, mainly engaged in producing and processing white fused alumina, dense fused, and bubble alumina.
This decision is made by determining how the abrasive will be used by the individual. Abrasives are sold in forms such as sheets, large/small discs, belts, and large/small rolls. Selecting the right form is determined by whether the abrasive will be used for hand. sanding, applied to a large disc
When functionalising fused alumina, a very thin layer of a silane adsorption group is applied to the fused alumina particles. This organic surface coating has the effect of better embedding and increased scratch resistance in a melamine resin matrix, for example. Fused alumina has a high refractive index (n =
Corundum is a mineral from the category of oxides and hydroxides and is the most frequently used industrial mineral worldwide. It also occurs naturally as a gemstone (sapphire, emerald, ruby). Chemically corundum is aluminium oxide with the chemical formula Al2O3.
Raw materials containing aluminium oxide are electrothermally melted at a reaction temperature of more than 2,000 °C to produce the various fused aluminas. Different starting materials are used depending on the desired type of fused alumina. For instance, bauxite is used for the manufacture of brown and semi-friable fused alumina,
Silicon carbide is a chemical compound of silicon and carbon and belongs to the group of carbides. The chemical formula is SiC.Silicon carbide is at the same time the hardest and lightest ceramic material and is also highly resistant against acids and alkaline solutions.
Silicon carbide (SiC) is produced from coke and quartz sand applying the Acheson process in an electric resistance furnace. When petrol coke and quartz sand are grouped around a graphite electrode and heated to a temperature of 2,000°C, black and slightly higher-quality green SiC are obtained. Green SiC has a
Corundum is the most frequently used abrasive. The purer the corundum, the harder it also is, which can be determined from the colour. The toughness can be increased by adding various metal oxides and by shortening the cooling process in production. The following distinctions are made: Brown fused alumina with
FEPA is the Federation of European Producers of Abrasives. Its mission is to develop and publish standards, documents and comprehensive safety instructions for the abrasive industry. Abrasive grain sizes are produced and sold according to the FEPA standard, among other things. This is to ensure that a consistent quality for

The d50 indicates the mean particle size. d50 means that 50% of particles fall within the specified grain size.
According to the FEPA, the bulk density of an abrasive is the quotient of the mass and the volume a grain type poured out in a particular manner will occupy. The bulk density, also called bulk weight, is stated in g/cm3. The rounder the particles, the higher the packing density,
The specific weight is the ratio of the weight of a body to its volume. The specific weight of corundum under normal conditions is 3.94 g/cm3.
