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, it provides a ruthenium-based ammonia decomposition hydrogen production catalyst for ammonia Application of decomposition to prepare carbon-free hydrogen.
Glass-ceramic is used in home appliance glass, induction cooker boards, and glass-ceramic casserole. Hebei Messi Biology Co., Ltd. said that adding magnesium oxide to glass-ceramic can adjust the crystallization temperature of the glass. At low temperature, it can slow down the decrease of glass viscosity, and at high temperature, it can accelerate the increase of
