Summary
"For the determination of the precise lattice constants of Ti2O3, it is very important to use a Ti2O3 as pure as possible. Due to the formation of solid solution with titanium or oxygen, ranging from 32.5 to. 34.5% O2 by weight in the Ti-O binary system, it is very difficult to get a pure Ti2O3 (33.8% O2 by weight) in the laboratory. To determine the precise lattice constants of pure Ti2O3, therefore, the extrapolation method was used. This method computes the respective constants for pure Ti2O3 from the values obtained With Ti2O3-Ti solid solutions by extrapolation. To carry out such an investigation on Ti2O3 the determinations as the following had to be made: 1) Determination of the exact lattice parameters of a substance having a composition close to Ti2O3. 2) Determination of the coefficients of thermal expansion (linear and volume expansion coefficients of the hexagonal and the rhombohedral unit cell, expansion coefficient of the axial ratio of the hexagonal unit cell, and interaxial angle expansion coefficient of the rhombohedral unit cell.) 3) Establishment of the change of the same parameters with small change in composition of the Ti2O3 -Ti solid solution. 4) Determination of the experimental densities and the molecular weights of Ti2O3-Ti solid solutions. These determinations would allow one: 5) To make conclusions concerning the perfection of Ti2O3-Ti solid solution and 6) To determine the parameters of pure Ti2O3. For the evaluation of soundness of the crystal lattice of Ti2O3, experimental macroscopic densities of the samples used had to be determined"--Introduction, pages 1-2
