Zircon firebricks for glass melting furnace

Zircon firebricks are a high-performance refractory material. Due to its excellent high-temperature strength, resistência à corrosão, and thermal shock stability, it is widely used in high-temperature fields such as glass industry, metalurgia, and building materials. This article will systematically introduce the production process of zircon bricks.

Zircon firebricks introduction

Zircon Mullite Brick is a dense refractory brick made of high-purity zircon sand (ZrSiO₄) and alumina (Al₂O₃) as the main raw materials. It reacts under high temperature conditions to form zircon mullite (ZrO₂·Al₂O₃·SiO₂) phase and is made through high-temperature sintering.

Zircon bricks for glass melting furnace

The molten glass and flame flying materials in the glass melting furnace will cause certain erosion and damage to the refractory materials, which will then affect the service life of the glass melting furnace. Além disso, it is necessary to avoid and reduce the pollution of the glass liquid. Portanto, the selection of refractory materials has a great relationship with the life of the glass melting furnace and the quality of the glass.

Zircon bricks for glass furnaces are made of zircon as the main raw material, with binders and additives added in proportion, and are stirred, mixed, formed, dried and fired at high temperature. Zircon bricks are divided into high-density type and dense type according to production process and physical and chemical indicators.

Application parts in the glass kiln

Where are dense zircon bricks for glass kilns mainly used? Zircon bricks are used for the working layer of the glass kiln pool wall. They have high density and are highly resistant to erosion by molten glass as the working layer of the pool wall.
