Zircon brick is a refractory product made of zircon as raw material and soft clay as a binder.

Zircon brick production process

After the zircon sand is pulverized, it is made into agglomerates, and after being calcined, it is pulverized into a suitable particle size. After batching → mixing → trapping → high-pressure molding → drying → high-temperature firing.
