The binary system Nb 2 O 5 — SiO 2 has been shown to include an extensive two‐liquid region over the range 5 to 80% Nb 2 O 5 . The minimum temperature of the two‐liquid area is 1695°C. A eutectic composition occurs at 95% Nb 2 O 5 and 1448°C. and another at approximately 5% Nb 2 O 5 and 1695°C. The experimental results were obtained by the cone‐fusion method.
