Toughened silicon carbide ceramic armor sheet and preparation method thereof
The invention discloses a toughened silicon carbide ceramic armor sheet and a preparation method thereof, the method adopts a technology of combining dispersed phase toughening and gel casting, adopts dispersed phase toughening of the same material, and performs toughening and reinforcing through boric acid to realize stress dispersion and directly realize preparation of high-initial-density silicon carbide ceramic; the preparation of the silicon carbide ceramic armor sheet can be realized on the premise of conventional low-temperature sintering without a tedious and complex preparation process, and the problem that high-temperature or high-pressure large-scale production is needed in the preparation process of silicon carbide ceramic is solved; the preparation method is simple, the relative distance between the ceramic powder is greatly shortened, rapid discharge of pores in the ceramic and densification of the ceramic are facilitated, the drying and cracking phenomena do not occur in the preparation process, and the prepared armor insert is high in forming precision.
本发明公开了一种增韧型碳化硅陶瓷装甲片及其制备方法，该方法采用弥散相增韧与注凝成型结合的技术，采用的是同种材料的弥散相增韧，并通过硼酸进行增韧补强，实现对应力分散，直接实现高初始密度碳化硅陶瓷的制备，无需繁琐复杂的制备工艺，能够在常规低温烧结的前提下实现碳化硅陶瓷装甲片的制备，解决了碳化硅陶瓷制备过程中需要高温或者高压的规模化生产难题；大大缩短了陶瓷粉末之间的相对间距，有助于陶瓷内部气孔的快速排出与陶瓷的致密化，制备过程未出现干燥开裂现象，制备出的装甲插片成型精度高。
