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. 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

1 Scope This method is suitable for the determination of magnesium oxide in soda-lime-silica glass. 2 principles The sample was dissolved in H2SO4 and HF. In the presence of pH 10 ammonia-ammonium chloride buffer solution, titrate with EDTA standard titration solution using acidic chromium deep-naphthol green B as indicator. 3 reagents 3.1 Triethanolamine (1+1). 3.2

Hebei Messi Biology Co., Ltd. stated that magnesium oxide is used in adsorption, catalysis, optical materials, electrode materials, antibacterial materials and chromatographic separation due to its non-toxic, large specific surface area, alkaline surface and rich active sites. plays an important role. In addition, due to its unique bandgap (7.8eV), heat resistance, insulation and heat conduction
