Product Description
Silica brick for Glass Kiln
Silica brick for glass furnaces is made of high purity quartzite and compound mineralizer with perfect grain size distribution, pressed and sintered. It has high Sio2, low flux(AL2O3+2R2O), low FE2O3, high refractoriness under load, low true density, low residual quartz, high tridymite and cristobalite. It could be directly laid without polishing because of uniform configuration and precise measurement. This product is widely used in glass klin wault, recuperator arch, face wall of charging hopper etc.
