Characteristics

The zirconia bubble brick is made from the bubble zircon and the ZrO₂, by adding moderate complex binder, and then through high pressure shape the product. It holds the features below

1.High refractoriness under load

2.Low reheating liner changing

3.Good performance

Application

The bubble zircon brick are mainly used for lining of high temperature furnace and industry ceramic, electrical ceramic, petrochemical and metallurgical industries, as well as the insulation material for super high temperature furnace.
