Hebei Messi Biology Co., Ltd. stated that in order to overcome the defects of poor catalytic activity and poor stability of ruthenium-based ammonia decomposition hydrogen production catalysts in the prior art under medium and low temperature conditions, a ruthenium-based ammonia decomposition hydrogen production catalyst is provided for the application of ammonia decomposition to prepare carbon-free
Hebei Messi Biology Co., Ltd. stated that adding magnesium oxide to microcrystalline glass can adjust the crystallization temperature of glass. At low temperatures, it can alleviate the decrease in glass viscosity, and at high temperatures, it can accelerate the increase in viscosity. Excessive iron and chloride in magnesium oxide will affect the color of glass.
