According to the process of this invention which involves adding the water-soluble iron compound to the magnesium-containing aqueous solution before or simultaneously with the addition of the alkaline compound, a high-density magnesia-calcia clinker is obtained which has a higher density than that obtained by a conventional process which involves adding the water-soluble iron compound after the addition of the …High density magnesia clinker and process for its ...According to the process of the present invention magnesia clinker having a higher bulk density is obtained by adding SiO 2 supply sources in such a manner that the SiO 2 content of magnesia clinker reaches 0.13 to 0.8 weight %, and further, high density and coarse crystal particle magnesia clinker is obtained by adding SiO 2 supply sources in such a manner that the SiO 2 content of magnesia clinker …Cited by: 8EP0140221A2 - Magnesia clinker and method of producing the ...The present invention discloses a magnesia clinker excellent in corrosion resistance, which is useful for a magnesia carbon refractory and also for a refractory for steel manufacturing furnace, and the magnesia clinker is characterized by: a having a purity of MgO of 97 wt. % or higher b containing 2.0 wt % or less of CaO; c containing 0.01 wt. % or more of B 2 O 3 ; d containing 0.3 wt. % or less of …Cited by: 7Magnesite Clinker - magnesium-supplier.comFor refractory Seven Trust materials, two-step calcination process is used to produce high purity and high density magnesia, and the main crystalline phases can be directly combined.
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.
