Low Sodium Manufacturer

The sodium(Na) content in most alumina is not high. Still, it is a factor that has a significant impact on the performance, resulting in reduced hardness, reduced cutting capacity, easy pulverization and crushing, and low thermal stability. Reducing the sodium content can significantly improve the melting point, particle density, bulk density, flexural strength, compressive strength, true density, hardness, etc. The adverse effect of Na is mainly caused by β- Alumina. It is used primarily in high-grade abrasives, special ceramics, and high-quality refractory materials.

Low Sodium FAQ

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

What is a silane coating used for?

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 =

What is melting vs. Sintering?

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

What is a mesh vs. Grit size?

If you take a (1) inch space and add wires to it, the number of openings within the 1″ space is defined as mesh. For example, if the 1″ space has ten openings for particles to fall through, then that sieve would be called a 10 mesh sieve. Typical sieve
