Apr 15, 2018· 1. Introduction. Magnesia is a very important basic Seven Trust material that is used widely in refractory and ceramics production because of its excellent corrosion resistance, heat resistance, and mechanical properties , , .To obtain high-performance products, it is necessary to use high-density magnesia in product manufacturing processes.Cited by: 7High-density periclase clinker: A promising material for ...High-density periclase clinker: A promising material for refractory production ... It is shown that by organizing production of high-density periclase powders in the plant from flotation magnesite concentrate with the minimum possible content of impurity SiO 2 and CaO oxides the quality of the ... This process is experimental and the keywords ...US3965240A - High density magnesia pellet and method for ...Caustic magnesia and magnesium hydroxide slurry are mixed together with sufficient energy in a counter-current high energy mixer to form pellets of various sizes during hydration of the caustic magnesia. The pellets may be used as formed or may be calcined to caustic magnesia or deadburned in a kiln to refractory periclase.Our Process and Magnesia Facts: Production of High Purity ...In a synthetic magnesia process, naturally occurring brine is mixed with both dolime and water to produce an aqueous suspension containing magnesium hydroxide and calcium chloride: CaCl 2 MgCl 2 H 2 O CaO MgO 2H 2 O —> 2Mg OH 2 2CaCl 2 H 2 O. CaCl 2 MgCl 2 H 2 O = brine. CaO MgO = dolime.
