Refractory Brick

Zirconia bricks produced by stable zircon sand with the advantage of mechanical strength, excellent stability to thermal shock, resistance to corrosion, high refractoriness under load and inertness, high density, etc. It is widely used in glass furnace, non-ferrous metal smelting furnace, and pure steel furnace.
