Types of high alumina refractories

Ordinary Alumina Oxide bricks: the main mineral composition of alumina bricks mullite, corundum and glass phase. With products in the aluminum oxide content.Increases, mullite and corundum phases increases the number, a corresponding reduction in the glass phase, products increase as refractoriness and high temperature performance
Modified alumina bricks: including high load soft high alumina bricks, high alumina bricks micro-expansion, low creep high alumina bricks, high alumina brick phosphate-binding.
