Medium temperature sintered new bone china and preparation method thereof
The invention discloses medium temperature sintered new bone china and a preparation method thereof. The medium temperature sintered new bone china is prepared from, by mass, 50-55% of bone charcoal, 20-30% of kaolin, 10-20% of feldspar, 5-15% of quartz and 5-10% of calcium sulfate nanofiber. The preparation method comprises the steps that bisque firing is carried out to 1250 DEG C for 8 h after raw material choosing smashing, compounding, dry powder ball grinding, calcium sulfate nanofiber adding, fineness detection, size mixing, discharging, screening for removing iron, filter pressing and squeezing mud, pugging, direct forming and drying are carried out, the temperature is kept for 30 min, cooling is performed, and then a new bone china bisque is obtained. The defects that traditional bone china is poor in bisque hardness, and poor in heat stability are overcome. The production method is scientific and reasonable, the technology is advanced, implement is easy, the yield is high, product quality is good, the sintering period can be greatly shortened, the sintering temperature is decreased, the production cost is significantly reduced, and therefore the market prospect is wide.
