The preparation of $TiB_2$ by SHS in $B_2O_3-Mg-TiO_2$ system was investigated in this study. In the preparation of $TiB_2$, the effect on reactivity and reaction products of the initial pressure of inert gas in reactor, the content of Mg and $TiO_2$ in mixture was investigated. The minimum initial pressure of inert gas in reactor for SHS reaction in this system was 5atm, and as the pressure increased, the concentration of unreacted Mg decreased and combustion temperature increased. At the initial inert gas pressure in reactor of 50atm, the optimum composition for the preparation of pure $TiB_2$ was $B_2O_3+5Mg+TiO_2$. The $TiB_2$ synthesized in this condition had an irregular shape and the particle size of $1~3{mu}m$.학회, 전주대학교 - 행사후원 : 한국디자인법인단체총연합회, 한국디자인진흥원, 디자인네트, 월간디자인,               광주문화재단 - 참가자 : 한국디자인학회 회원 및 비회원 - 참가비 : 회원 (사전등록자 및 예약자 8만원)               학생회원 (사전등록자 및 예약자 5만원)               회원 ( 현장등록자 10만원)               비회원 20만원 ( 사전등록 18만원) - 제공내역 : 숙박, 3식(석식, 조식, 중식 제공), 워크샵 수료증, 워크샵북 증정   Ā吀
