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.
The description of the grain shape can range from “angular” to “acicular” to “spherical”. When the value of the dimensionless form factor is 1, the grain is spherical. The smaller the form factor, the pointier the grain.
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 =
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).
When processing minerals in a furnace, materials can either be melted or sintered. When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process creating uniformity in the chemistry throughout the entire batch. The sinerting process
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
We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.

On February 3, the deputy mayor of Sanmenxia led the comrades in charge of the Municipal Development and Reform Commission, Municipal Finance Bureau, Municipal Industry and Information Bureau, Municipal Ecological Environment Bureau and other relevant departments to go
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,
