Preparation method of high-strength and high-modulus reactive sintering silicon carbide material
The invention relates to a preparation method of a high-strength and high-modulus reactive sintering silicon carbide material. The preparation method comprises the following steps: (1) mixing carbon black, silicon carbide micro powder, deionized water, a water reducing agent, a dispersing agent, a thickening agent and a binder, and carrying out vacuum defoaming to obtain water-based slurry; (2) carrying out hollow pouring and drying on the obtained water-based slurry to obtain a ceramic biscuit; and (3) carrying out vacuum debonding and liquid-phase siliconizing on the obtained ceramic biscuit to obtain the high-strength and high-modulus reactive sintering silicon carbide material.
本发明涉及一种高强度高模量的反应烧结碳化硅材料的制备方法。该制备方法包括：(1)将碳黑、碳化硅微粉、去离子水、减水剂、分散剂、增稠剂和粘结剂进行混合和真空除泡，得到水基浆料；(2)将所得水基浆料进行空心浇注和干燥，得到陶瓷素坯；(3)将所得陶瓷素坯经真空脱粘和液相渗硅，得到所述高强度高模量的反应烧结碳化硅材料。
