Abstract
The Hall coefficient of titanium has been measured over a temperature range from 350°K to 1100°K. The coefficient is −2.0×10−11m3/coulomb near room temperature, reverses sign at (675±30)°K, and increases to a value of +3.5×10−11m3/coulomb at 1100°K. The measurements were made on titanium samples which had a purity of 99.99%. The samples were heated by direct current, and the temperatures were determined indirectly from the resistivity measurements which were made with each Hall measurement. The resistivity is 0.48 microhm m at 350°K. It increases to a maximum of 1.76 microhm m at the crystal transition temperature.
