Manufacturing method of environment-friendly pressureless sintered boron carbide ceramic material
The invention belongs to the technical field of ceramic materials, and particularly relates to a manufacturing method of an environment-friendly pressureless sintered boron carbide ceramic material, which comprises the following steps: (1) adding deionized water, a CMC binder, a dispersing agent and a water reducing agent into a ball mill, carrying out ball milling until the substances are uniformly dispersed, then adding boron carbide raw powder, and carrying out ball milling to obtain a slurry; continuously carrying out ball milling for a certain time to obtain stably dispersed modified boron carbide slurry; (2) adding a release agent into the modified boron carbide slurry obtained in the step (1), ball-milling to target viscosity, and sieving for later use; (3) performing spray granulation on the slurry obtained in the step (2) to obtain granulation powder; (4) taking the granulation powder obtained in the step (3), and carrying out wet isostatic pressing tabletting under a certain pressure intensity to obtain a biscuit; (5) performing vacuum high-temperature degumming on the biscuit; (6) preparing a carbon source mixed penetrating solution, and performing vacuum carburization on the biscuit by using the prepared carbon source mixed penetrating solution; and (7) drying and sintering the sample subjected to vacuum carburization.
本申请属陶瓷材料技术领域，具体涉及一种环保型无压烧结碳化硼陶瓷材料的制造方法，包括如下步骤：（1）将去离子水、CMC粘结剂、分散剂、减水剂加入到球磨机，球磨至各物质分散均匀后加入碳化硼原粉，继续球磨一定时间得到分散稳定的改性碳化硼浆料；（2）向步骤（1）获得的改性碳化硼浆料中加入脱模剂，球磨至目标粘度，过筛备用；（3）将步骤（2）获得的浆料进行喷雾造粒，获得造粒粉；（4）取步骤（3）获得的造粒粉，在一定压强下进行湿式等静压成型压片，获得素坯；（5）将素坯进行真空高温脱胶；（6）配制碳源混合渗透溶液，并用所配制的碳源混合渗透溶液对素坯进行真空渗碳；（7）将真空渗碳后的样品烘干、烧结。
