Bubble Alumina (alumina bubble) is produced by high purity industry alumina in electric arc furnace products. The product chemistry is similar to that of white fused alumina. Alumina bubbles are formed from α-alumina, resulting in hollow spheres of low bulk density and high insulating property. At high temperatures, they have good chemical stability and corrosion resistance.
Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit). Superfine grits run from 150 and higher. Grinding wheels usually will be between 24 and 100 grit. Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher.
Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials. A typical weak bond for steel would be in the ‘F, G or H’ range. A
Grit type is either aluminum oxide (white, pink, ruby red, brown, grey, etc.) silicon carbide (black or green), ceramic (blue and pink) or any combination of these. Grit types are sometimes mixed in combination for achieving certain cutting characteristics. Aluminum oxide is friable (white) or semi-friable (pink, brown and grey, red,
Structure is basically the spacing between abrasive grains. An open structure would be 12 or higher while a closer structure would be 6 or so. Here again, the structure depends on a variety of factors not the least of which is how difficult the material is to grind.
Abrasive grains – usually aluminum oxide or silicon carbide Bonding agent – usually a resin bond Spacing of grains within the bond – determine porosity and strength
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 =

‘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,
