White fused alumina

White fused alumina is suitable as iron-free medium and used for applications in the abrasive and refractory industry and as a jet-material in the aluminium-, optical and dental industry. Because of its transparency and its scratch resistance, white fused aluminium is also used in resins and coatings in the laquer and laminate industry.
