RECYCLED ALUMINIUM SILICATE MATERIAL AND A PARTICULATE MIXTURE COMPRISING RECYCLED ALUMINIUM SILICATE MATERIAL

摘要

The present invention relates to a recycled aluminium silicate material, suitable for use in ceramic article production, wherein the recycled aluminium silicate material has a particle size distribution such that: (i) the d50 particle size is from 10µm to 30µm; (ii) the d70 particle size is less than 40µm; and (iii) the d98 particle size is less than 60µm. The present invention also relates to a particulate mixture, suitable for use in ceramic article production, comprising the above defined recycled aluminium silicate material.
