Preparation process of high-thermal-stability purple sand ceramic
The invention relates to the technical field of high-thermal-stability purple sand ceramics, in particular to a high-thermal-stability purple sand ceramic preparation process which comprises the following steps: S1, raw ore collection; S2, open-air ore drying; S3, raw material crushing: 20% of spodumene is added into weathered and cracked mineral raw materials by adopting a crusher for crushing; s4, ball milling; s5, squeezing mud; s6, pugging; s7, aging is conducted; s8, forming a green body; s9, drying the green body; s10, fettling is conducted; s11, firing is carried out; s12, polishing is conducted; according to the invention, 20% of spodumene is added in the crushing process, so that the cracking phenomenon of the product is avoided, the thermal expansion coefficient of the purple clay pot can be obviously reduced, and the purple clay pot has good heat-resistant stability.
本发明涉及高热稳定性紫砂陶瓷技术领域，具体涉及一种高热稳定性紫砂陶瓷制备工艺，包括有以下步骤：S1：原矿采集：S2：露天晒矿S3：原料粉碎：采用破碎机对风化裂解后的矿物原料加入20％的锂辉石进行破碎；S4：球磨；S5：榨泥；S6：练泥；S7：陈腐；S8：坯体成型；S9：坯体干燥；S10：修坯；S11：烧成；S12：打磨；本发明通过在粉碎过程中加入20％的锂辉石，未见产品开裂的现象，能够显著的降低紫砂煲的热膨胀系数，使其具有良好的耐热稳定性能。
