High Dense Zircon Bricks

Zircon Bricks

Zircon Bricks, a kind of shaped refractory brick, are manufactured with stable zircon sand and over 64% zircon content. Zircon Brick belongs to acid refractory material with various properties of high mechanical strength, good thermal shock resistance, high refractoriness under load, strong erosion resistance and high density and etc. Zircon Bricks can be widely used in glass furnace, Ladle, pure steel furnace, non-ferrous metal smelting furnace and so on.
