Preparation process of zirconia ceramic block gauge
In order to solve the problem that an existing ceramic block gauge material has risks of damage and deformation in the later machining and using process, the invention provides a preparation process of a zirconia ceramic block gauge, and the process comprises the steps of burdening, grinding, drying, blank making, sintering, aging treatment, machining, secondary aging treatment, aftertreatment andthe like. According to the preparation process of the zirconia ceramic block gauge, aging treatment and secondary aging treatment are added in the process; the prepared semi-finished product and crude product are placed in the natural environment; residual thermal stress in the ceramic block gauge during hot press molding and stress in the machining process can be fully released so that semi-finished products and crude products are more stable, the yield and size stability of finished ceramic block gauges are improved, the ceramic block gauges are prevented from being damaged or deformed in the later machining and using process, and the high yield is guaranteed.
本发明为现有陶瓷块规材料在后期加工以及使用过程中存在着损坏以及变形的风险问题，提供一种氧化锆陶瓷块规的制备工艺，该工艺包括配料、研磨、干燥、制坯、烧结、时效处理、机加工、二次时效处理和后处理等步骤。本发明提供一种氧化锆陶瓷块规的制备工艺，工艺中增加了时效处理和二次时效处理，制备的半成品和粗品在自然环境中敞放，能够充分释放其内部热压成型时残留的热应力以及机加工过程中的应力，使得半成品和粗品更加稳定，提高陶瓷块规成品的良品率和尺寸稳定性，从而防止其在后期加工以及使用过程中损坏或者变形，保证较高的良品率。
