The invention discloses a fused quartziferous cast glazed tile for a coke oven. The glazed tile comprises glazed water and a cast prefabricated member, wherein the glazed water comprises following components in percentage by weight: 30-50% of spodumene with a particle size of 10 to 0 micron, 5-20% of soft clay with the particle size of 10 to 0 micron, 10-20% of potash feldspar with the particle size of 10 to 0 micron, 5-15% of aluminum oxide with the particle size of 5 to 0 micron, 3-15% of quartz with the particle size of 10 to 0 micron, and 0.5-1% of organic plasticizer. The cast prefabricated member includes the following ingredients in percentage by weight: 30-50% of fused quartz, 25-35% of chamotte, 10-15% of alumina clinker, 10-15% of binding agent, 3-6% of silicon micropowder and 3-8% of aluminum oxide micropowder. Meanwhile, the invention further discloses a preparation method of the glazed tile. The glazed tile provided by the invention has excellent thermal shock stability and thermal impact resistance in coke oven production process; the glazed tile has low thermal conductivity and high strength, and can effectively reduce the external temperature of the furnace gate; and the production process does not have pollution.
