What is Durolox ?


" DURALOX IS A REGISTERED TRADE NAME OF JYOTI FOR ALUMINIUM OXIDE CERAMIC COMPOSITE "

DURALOX is a single component oxide of corundum crystals bonded by solid state reaction during the sintering process. It is a specially developed proprietary alumina ceramic composite containing 92% micro fine alpha alumina crystals, most suitable composite for producing wear corrosion resistant lining tiles and components. Duralox wear resistant tiles are sapphire hard, tough, inert, non porous, smooth in surface and resistant to abrasion-corrosion under most severe conditions extending the productive life of a wide variety of bulk material handling and processing equipment.
