What are the main components used in the construction of bonded abrasives?
Abrasive grains – usually aluminum oxide or silicon carbide Bonding agent – usually a resin bond Spacing of grains within the bond – determine porosity and strength

Dense Fused Alumina for Refractory is a new high-purity refractory material formed by using high-purity alumina and reducing agents in a specific ratio, smelting in an electric arc furnace and cooled. The main crystal phase is α-Al2O3, and the color is light gray. Dense Fused Alumina for Refractory used dense alumina has a high melting point and a high-volume density, which melted at high temperature and constant temperature in an advanced electric melting tilting furnace. DFA is the ideal material for unshaped and shaped refractories, such as tapping trough of blast furnace, castables for ladle, ramming mix, prefabricated parts, extended nozzle, submerged entry nozzle, stopper, porous brick and nozzle seating brick, etc.

Yes, No problem, but Customer resposiable for the charge.
The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).
The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in abrasives are very sensitive to changes in temperature and humidity. Abrasives are best stored at temperature levels of 60 to 80 degrees Farenheit and a
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,
Moisture contamination is the number one reason customers call Technical Support. Fortunately, it is usually preventable. There are 4 key ways to keep your abrasive free of moisture:1.Store abrasive properly and always make sure bottles are tightly closed when not in use.2.Keep abrasive in a cool dry location with minimum

‘TAOANG’ means ‘Make Waves’ in Chinese, while ‘Promote the truth’ in Taoism. Henan Taoang Industrial was established and developed by the Yellow River, making waves in the industry and promoting the truth in business. TAOANG CORE VALUES: EQUALITY,
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,
