Abstract
1. A study was made of the decomposition kinetics of titanium carbides in mixtures of sulfuric acid (from 0.5 to 10 g-eq/liter) and hydrogen peroxide (from 1.08 to 6.44 g-eq/liter) at temperatures of 25–80°C. 2. As the concentration of sulfuric acid is raised from 0.5 to 5 g-eq/liter, the dissolution rate of titanium carbides falls, but at acid contents ranging from 5 to 10 g-eq/liter it is independent of solution acidity. With rise in hydrogen peroxide concentration, the decomposition rate of titanium carbides decreases. 3. The smaller the deficiency of carbon in the carbide, the greater is the stability of the compound in mixtures of sulfuric acid and hydrogen peroxide.
