ceramic  raw materials

 Calcined alumina for ceramics, refractories and surface treatment.

Combined with state of the art process control equipment we are able to produce a range of high alpha alumina grades with controlled soda chemistry, surface area and partied size distributions.We provide alumina products are used in a wide grange of refractory applications, such as: fired shapes, monolithics and pre-case shapes used in foundry, iron and steel making applications.Ceramic grades are used in the manufacture of grinding media, glazes, technical and advanced ceramics.Alpha alumina is also used in surface treatment applications, careful control of physical properties allow its as a metal polish and buffer in addition to surface that require a specific finish.
