Abstract
The coating process of TiH 2 particles with SiO 2 layers, and the effect of the coating layer on gas release characteristic of TiH 2 powders were studied experimentally. The pH value of reactive solution and gelation rate of silicic acid are important factors for controlling surface morphologies of coating layers. When pH value is about 4.0 and concentration of silicic acid is about 0.5 mol/L, respectively, the condensation rate of silicic acid is appropriate for the formation of a homogeneous and dense coating membrane. The results of gas release at 700 ∘ C show that TiH 2 particles coated with silicon dioxide layers can efficiently delay the starting time of gas release of TiH 2 powders by 60–100 s.
