The invention provides a celadon blank making technology through
overweight pressure one-time moulding. The celadon blank making technology comprises the following steps of (1) preparing
raw material powder; (2) performing compression moulding; (3) performing
sintering on compressed blanks, wherein the
sintering temperature is controlled to 1190-1300 DEG C; and (4) trimming the blanks so as to obtain the celadon blank. Raw materials for preparing the
raw material powder comprise 35-45% of Longyan kaolin, 15-20% of celadon blank clay
powder, 8-20% of
potassium feldspar, 7-12% of
quartz, 3-8% of
hematite, 5-10% of Zijin clay, 6-10% of
bone ash, 9-15% of nanometer alpha-Al2O3 powder, and 5-10% of filler. According to the celadon blank making technology disclosed by the invention, the refractoriness of blanks is greatly improved, besides, the made blank has the advantages of being high in strength, natural in glossiness, and fine in texture, and the celadon blank can be produced in batches, and the production cost is reduced.
