Bubble Alumina

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.

Bubble Alumina(FAQ)

What is the d50 value?

The d50 indicates the mean particle size. d50 means that 50% of particles fall within the specified grain size.

What is the structure?

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.

Why is corundum or silicon carbide used?

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

How do i prevent moisture contamination in the abrasive?

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
