Porosity is defined as the gas proportion (cavity volume) of a particle’s total volume. It can be determined using different measurement techniques, such as gas adsorption and mercury porosimetry. With the same grain size and shape, a lower

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

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

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
