Refractory bricks used in glass melting pools are susceptible to corrosion from direct contact with molten glass. The liquid glass temperature can reach 1500°C, requiring refractory bricks with high corrosion resistance. Maintaining stability at the refractory-glass interface and preventing spalling are also important to avoid glass defects. Zhengzhou Sunrise Refractory is a manufacturer of refractory products for the glass industry, including fused cast bricks and mullite, zircon, and magnesia bricks.

1. Refractory Brick Contacted Glass Liquid In Melting Pool
The damage mechanism of most refractory materials which contact glass liquid is liquid
phase corrosion, and it is dominated by diffusion / permeability. So there is high requirement
to refractory bricks which are contacted glass liquid directly in melting pool.
The liquid temperature of soda lime glass is as high as 1500 , except for soda lime glass,℃
the temperature of other glass liquid maybe higher or lower which depends on the
requirements of glass viscosity characteristics and the glass composition. As to all the parts
that contact glass liquid, the most important property of refractory brick is the ability of
corrosion resistance. The interface stability of refractory materials and the tendency of
producing stone are almost equally important, and the interface stability refers to part of the
efractory material is in the erosion state, but the surface of the refractory material is complete
and does not fall off and causes the glass to produce defect.
