Abstract

Interest in the titanium boride system stems from a patent disclosure by Vahldiek in 1982. In that disclosure TiBx(x=1.6) crystals were subjected to pressures of 300,000 psi and found to have vanishingly low resistivities at room temperature. In this study we processed TiBx crystals by a variety of techniques and pressurized the samples up to 350,000 psi. No high temperature superconductivity was observed.
