Features of Hydride Synthesis

Lithium, sodium, and titanium hydrides have been synthesized. It has been found that lithium hydride is formed at a temperature of 650-700°C and a pressure of 12 atm. Lithium hydride contains 11 mass.% of hydrogen. Hydrogen desorption from lithium hydride occurs at a temperature of 700°C. Lithium hydride decomposes in water to form lithium hydroxide and hydrogen. Sodium hydride is formed at a temperature of 300-450°C with a hydrogen absorption level of up to 4 mass%. Hydrogen desorption from sodium hydride occurs at a temperature of 350-400°C. Titanium hydride is formed at a temperature of 600-650°C with a hydrogen absorption level of up to 4 mass%. Hydrogen desorption from sodium hydride occurs at a temperature of 450-650°C. Lithium, sodium, and titanium hydrides can be used in hydrogen storage and transportation processes.
