The influence is examined of small percentages of SiO/sub 2/ at high temperature (1650 deg C) on the phase relations between TiO/sub 2/-ZrO/sub 2/. The equilibrium isotherm of the ternary system is examined. Experimental results of reflection microscopy and x-ray examinations show that small amounts of SiO/ sub 2/ form-at 1650 deg C-with TiO/sub 2/ and ZrO/sub 2/ a fused mass (5 to 10% of the total mass) without altering substantially the phase relations existing between TiO/sub 2/ and ZrO/sub 2/. The study of the ternary system at 1400 deg C shows the presence of a binary equilibrium line, of three zones in which exist two phases, and of three zones in which three phases are present. The graph of the probable isotherm of the ternary system, at 1400 deg C, is given. (auth)
