Hobaneng ha oxide ea magnesium e hanela mocheso o phahameng? Ke mocheso ofe moo magnesium oxide e ka fihlelang ho sintering? Mocheso oa sintering oa magnesium oxide ke eng?
Hobaneng ha oxide ea magnesium e hanela mocheso o phahameng? Ke mocheso ofe moo magnesium oxide e ka fihlelang ho sintering? Mocheso oa sintering oa magnesium oxide ke eng?
Magnesium oxide e tsejoa e le mobu o bohloko, kapa magnesia, e nang le qhibiliho ea 2852 ° C, ntlha e belang ea 3600 ° C, le letsoalo le lekanang la 3.58 (25 ° C). Qhibilihang ka har’a asiti le ammonium letsoai tharollo, insoluble ka joala. Magnesium oxide e na le thepa e phahameng e hanyetsang le e sireletsang. E ka fetoloa likristale ka mor’a ho chesoa ka mocheso o phahameng ho feta 1000 ° C. Ha e nyolohela ho 1500-2000 ° C, e fetoha magnesia e shoeleng e shoeleng (e tsejoang hape e le magnesia) kapa sintered magnesia.
Kenyelletso ea Magnesium oxide:
Magnesium oxide (mokhoa oa lik’hemik’hale: MgO) ke magnesium oxide, motsoako oa ionic. E tiile e tšoeu mochesong oa kamore. Magnesium oxide e teng ka tlhaho ka mokhoa oa periclase ebile ke sesebelisoa sa lihlahisoa tsa smelting magnesium.
Magnesium oxide e na le litšireletso tse phahameng tsa mollo le thepa ea ho e kenya. Kamora ho chesoa ka mocheso o phahameng ho feta 1000 ° C, e ka fetoloa likristale. Ha e nyolohela ho 1500-2000 ° C, e tla chesa magnesia (e tsejoang hape e le magnesia) kapa sintered magnesia.
Magnesium oxide ka Senyesemane ke Magnesium oxide kapa Magnesium monoox
Li-oxide tsa magnesium ke eng?
Magnesium oxide e arotsoe ka mefuta e ‘meli: magnesia e bobebe le magnesia e boima.
Litšobotsi tsa khanya ea magnesium oxide ke eng?
E bobebe ebile e le kholo, ke phofo e tšoeu ea amorphous. Ha e na monko, ha e na tatso ebile ha e na chefo.
Sekhahla sa khanya ea magnesium oxide e kae? Boikarabello ke 3.58g / cm3. Ha e qhibilihe ka metsing a hloekileng le li-solvents, ‘me ho qhibiliha ha eona ka metsing hoa eketseha ka lebaka la boteng ba carbon dioxide. E ka qhibiliha ka asiti le tharollo ea letsoai la ammonium. E fetoloa likristale ka mor’a ho chesa ha mocheso o phahameng. Ha carbon dioxide e le moeeng, ho etsoa letsoai le habeli la magnesium carbonate.
Taba e boima e kopane ka molumo ‘me e tšoeu kapa phofo ea beige. Ho bonolo ho kopana le metsi, ‘me ho bonolo ho monya mongobo le carbon dioxide moeeng o pepesitsoeng. Ho bonolo ho gel le ho thatafala ha o kopantsoe le tharollo ea magnesium chloride.
