Abstract
The enthalpies of transformation of pure, well‐characterized samples of brookite and anatase to rutile were determined by solution calorimetry in a 3Na2O·4MoO3 melt at 971 ±2 K. The experiments gave the following results: brookite→rutile, ΔH°971= ‐0.17±0.09 kcal mol−1; anatase → rutile, ΔH°971= ‐0.78±0.20 kcal mol−1.Keywords
