Boron carbide ceramic and preparation method thereof
The invention discloses boron carbide ceramic and a preparation method thereof. The preparation method of the boron carbide ceramic comprises the following steps: subjecting boron carbide powder, additives and water to mixing and ball milling so as to allow the additives to be adsorbed on the surface of the boron carbide powder to obtain primary slurry, wherein the additives comprise a binder and a plasticizer; removing bubbles in the primary slurry to obtain tape casting slurry; preparing a boron carbide sheet by adopting the tape casting slurry; and carrying out hot press sintering on the boron carbide sheet to obtain the boron carbide ceramic. The boron carbide ceramic is prepared by adopting the above method. The preparation method provided by the invention is simple in process and low in equipment investment, and the obtained ceramic is uniform in tissue structure and high in strength.
本发明公开了碳化硼陶瓷及其制备方法。碳化硼陶瓷的制备方法，包括：将碳化硼粉体、添加剂和水混合球磨使添加剂吸附在碳化硼粉体表面得到初级浆料，添加剂包括粘结剂和增塑剂；去除初级浆料中的气泡得到流延浆料；采用流延浆料制得碳化硼薄片；将碳化硼薄片热压烧结得到碳化硼陶瓷。碳化硼陶瓷，采用上述方法制得。本申请提供的制备方法工艺简单，设备投资小，得到的陶瓷组织结构均匀，强度高。
