Abstract
ZrB 2–SiC ceramics are prepared by pressureless sintering using ZrB 2 powders and liquid polycarbosilane (LPCS) precursors. The LPCS can effectively reduce the sintering temperature. The phases of the sintered ceramics are characterized by X-ray diffraction, and their morphologies are observed by scanning electron microscopy. From these results, it is learned that LPCS can provide free carbon and silicon at high temperatures. Therefore, the oxides on the ZrB 2 surface can be removed by free carbon, and the densification process can be promoted by silicon. These coupled effects make it possible to pressureless sinter the ZB 2–SiC ceramics at low temperatures.
