High-temperature and high-pressure preparation method of high-strength boron carbide ceramic
The invention discloses a high-temperature and high-pressure preparation method of high-strength boron carbide ceramic. The method comprises the following steps: (1) kneading treatment: weighing calculated amounts of a boron carbide ceramic raw material, a dispersing agent and a carburant, and kneading; (2) pressing and forming: pressing the mixed and kneaded material in the step (1) into a columnshape; (3) low-temperature drying: carrying out low-temperature drying treatment on the columnar material in the step (2); (4) carbonization and reduction treatment: putting the columnar material subjected to low-temperature drying treatment in the step (3) into a reduction furnace, and carrying out carbonization and reduction treatment; (5) assembling: putting the columnar material subjected tocarbonization reduction treatment in the step (4) into a pyrophyllite mold for assembling; and (6) press synthesis: putting the pyrophyllite mold assembled in the step (5) into a cubic press for presssynthesis to obtain the boron carbide ceramic. According to the method, the high-strength boron carbide ceramic can be simply and rapidly sintered, the yield is increased, and the production cost issaved.
本发明公开了一种高强度碳化硼陶瓷的高温高压制备方法，包括以下步骤：（1）混捏处理：称取计算量的碳化硼陶瓷原料、分散剂和增碳剂进行混捏；（2）压制成型：将步骤（1）中混捏后的物料压制成柱状；（3）低温烘干：将步骤（2）中柱状物料进行低温烘干处理；（4）炭化还原处理：将步骤（3）中低温烘干处理后的柱状物料放入还原炉中，进行炭化还原处理；（5）组装：将步骤（4）中炭化还原处理后的柱状物料放入叶腊石模具中进行组装；（6）压机合成：将步骤（5）中组装后的叶腊石模具装入六面顶压机中进行压机合成，即制得碳化硼陶瓷。本发明能实现简单快速烧结高强度碳化硼陶瓷，提高成品率，节约生产成本。
