Dense Zircon Brick

    This brick is such an excellent refractory product that is able to contact with the molten glass directly, because its chemical inertness can avoid being contaminated by the colored patches of glass and the defects of stria and concretion. It can enhance the quality of the glass and prolong the service life of the glass tank. It is the preferred material for the lining of the alkali-free glass fiber melting tank. It also can be used in the glass tank for borosilicate glass, ceramic glass, low-alkali glass, etc.
