The invention relates to a preparation method of a low-cost high-alumina ceramic thin plate. The preparation method of the low-cost high-alumina ceramic thin plate is characterized by including the steps: 1) raw material treatment; 2) raw material proportioning and mixing: weighing raw materials including, in weight percent, 10%-25% of coal series kaolinite, 10%-25% of calcined bauxite, 20%-30% ofcommon kaolinite, 15%-25% of feldspar, 0-5% of talcum and 18%-25% of quartz to obtain a blank; adding reinforcing agents equivalently accounting for 0.1%-0.25% of the total weight of the blank, performing ball milling for 12-18 hours and uniformly mixing the raw materials to obtain mixed materials; 3) pelleting and aging; 4) semi-dry pressing; 5) drying; 6) glazing; 7) sintering to obtain the low-cost high-alumina ceramic thin plate. The feldspar is formed by mixing potassium feldspar with soda feldspar, and the weight ratio of K2O to Na2O of the mixed feldspar chemical composition is 2:1. The sintering temperature of the high-alumina ceramic thin plate prepared by the method is only 1180 DEG C, so that the ceramic thin plate is low in cost and high in strength.
