Self-propagating High Temperature Synthesis of TiB 2

Abstract

Abstract Self-propagating high temperature synthesis (SHS) is a very important technique for the synthesis of high technology ceramics, metals and alloys. SHS parameters of TiB 2 were carried out in this study. Mg stoichiometry as reductant, process atmosphere and addition of NaCl and MgSO 4 ·7H 2 O additives were investigated. HCl leaching was applied to SHS products to purify their TiB 2 contents. Stoichiometrically 100% Mg addition ratio and Ar atmosphere were determined as the optimum parameters. NaCl addition was also positively affected the specific surface area values. 11.78 m 2 /g specific surface area value was measured for 5.0% NaCl addition ratio.
