Hebei Messi Biology Co., Ltd. stated that it has been preparing nano-form metal oxides through the sol-gel method for some time. This type of reaction process is based on the hydrolysis of metal salts, thereby producing the required metal hydroxides and pure salts. During the condensation of molecules, accompanied by the removal of water, a

Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide, as an important inorganic chemical product, can be used as a flame retardant for polymer materials, flue gas desulfurizer, smoke suppression additive and green water treatment agent. In addition, it is also widely used in ceramics, medicine, food and other fields. Nano-magnesium hydroxide can also be
Hebei Messi Biology Co., Ltd. said that in the salt chemical industry in Haiyan area, bitter brine, thick brine, and high-temperature salt are mainly used as raw materials to produce magnesium carbonate or magnesium oxide. Industrialized production methods include soda ash method, lime method and ammonium bicarbonate method. (1) The process conditions controlled by each
Hebei Messi Biology Co., Ltd. stated that one of the current synthesis routes for nano-magnesium oxide materials is the ultrasonic method. This method performs chemical reactions in ultrasonic waves with frequencies between 10Hz and 20MHz. Ultrasound can continuously form and destroy microbubbles, creating “hot spots” at temperatures and pressures of 5000K and 1000atm respectively. Compared
