Sintered magnesite by magnesite, water MeiKuang or extracted from the sea by high temperature firing magnesium hydroxide and into. Strong ability of hydration. Magnesite in 700-950 °C calcined under that CO2, the escape from magnesia as soft porous loose material, can not be used in refractory materials; Magnesite 1550 1600 °C the calcined magnesite burned the so-called sintered magnesite says. Intermediate magnesia is MgO style content is 97% of the light burning magnesium oxide as the raw material, the pressure the ball, high temperature shaft kiln firing technology production and into. And Products sintering degree good, crystallization density, is the production intermediate magnesia refractory products of high quality raw materials. Magnesia is the most important refractory raw material, is used to make all kinds of one of magnesia brick, magnesium aluminum bricks, ramming materials, filling the burden, etc. Containing impurities more, for the bottom of the LianGangLu roadways.
