Abstract
The invention provides a lip tile, which is prepared from the following raw materials by weight percent: 35-45% of tabular corundum, 25-35% of aluminum oxide, 10-20% of zircon sand and 15-20% of mixture, wherein the mixture comprises the following components by weight percent: 25-45% of phosphoric acid or phosphate, 10-20% of boron anhydrous, 40-60% of alpha-Al2O3 micro powder and 2-5% of calcium compound. The tabular corundum good in sudden change resistance and erosion resistance is employed as the aggregate of the lip tile; therefore, the lip tile is good in sudden change resistance and erosion resistance, long in service life, and capable of improving the quality, yield and benefit of a glass product; and the lip tile is low in cost.
