Preparation method capable of lowering production cost of Nixing ceramics
The invention discloses a preparation method capable of lowering the production cost of Nixing ceramics. A blank is prepared from the following raw materials in parts by weight: 45-60 parts of east clay, 25-50 parts of west clay, 1-2 parts of bentonite, 1-3 parts of wollastonite, 0.6-0.8 part of red clay, 0.2-0.4 part of konilite and 1-3 parts of aluminum oxide. The preparation method comprises the following steps: sintering: (a) heating to 75-90 DEG C at a speed of 35 DEG C/h-50 DEG C/h, and maintaining the temperature for 6-8 hours; (b) heating to 125-140 DEG C at a speed of 45 DEG C/h-60 DEG C/h, and maintaining the temperature for 2-4 hours; (c) heating to 500-550 DEG C at a speed of 65 DEG C/h-80 DEG C/h, and maintaining the temperature for 0.2-0.4 hour; (d) heating to 800-850 DEG C at a speed of 65 DEG C/h-80 DEG C/h, and maintaining the temperature for 0.1-0.3 hour; and (e) heating to 1020-1040 DEG C at a speed of 85 DEG C/h-100 DEG C/h, and maintaining the temperature for 0.6-0.8 hour.
