High-toughness boron carbide ceramic and preparation method thereof
The invention relates to a high-toughness boron carbide ceramic and a preparation method thereof. The preparation method comprises the following steps: a) preparing mixed powder, wherein the mixed powder comprises the following components in percentage by weight: 80-90% of boron carbide powder, 5-10% of microporous carbon and 5-10% of titanium powder; b) uniformly mixing an adhesive with the prepared mixed powder, and preparing the mixture into a ceramic blank; c) after the prepared ceramic blank is dried, carrying out adhesive discharge at a required temperature, thus obtaining a porous perform; and d) reacting the porous perform with silicon powder at a temperature of 1450-1600 DEG C, thus obtaining the high-toughness boron carbide ceramic.
