Firing method of Nixing pottery
The invention provides a firing method of Nixing pottery, which comprises the following steps: preparing a blank, forming a green body, trimming the green body, drying the green body, and firing the green body, and the blank is prepared by adding 0.001-0.002% of NaCl on the basis of Nixing pottery clay; in the step of blank firing, the temperature of a dried green body is increased to 300 DEG C atthe speed of 50-80 DEG C/h, the pressure is adjusted to 6-10 KPa, heat preservation and pressure maintaining are conducted for 5-10 min, and normal air pressure is recovered; the temperature is increased to 950 DEG C at the speed of 100-120 DEG C/h, the pressure intensity is adjusted to 6-10 KPa, the temperature and the pressure are kept for 10-15min, and the normal air pressure is recovered; andthen the temperature is raised to 1100-1200 DEG C, and natural cooling is carried out. The Nixing pottery fired by the method is good in thermal shock resistance, can be directly used on various heatsources, is not cracked for a long time, and can meet the standard requirements of QB/T2580-2002 Fine Ceramic Cooker.
本发明提供了坭兴陶的烧制方法，包括制备坯料、坯体成型、修整坯体、坯体干燥、坯体烧制，所述坯料是在坭兴陶泥料的基础上加入0.001～0.002％的NaCl；所述坯体烧制是将干燥坯体先以50～80℃/h的速率升温至300℃，调整压强至6～10KPa并保温保压5～10min，恢复正常气压；再以100～120℃/h的速率升温至950℃，调整压强至6～10KPa并保温保压10～15min，恢复正常气压；然后升温至1100～1200℃，自然冷却。本发明烧制的坭兴陶抗热震性能较好，能直接在各种热源上使用，经久而不开裂，可满足QB/T2580‑2002《精细陶瓷烹调器》的标准要求。
