Chifukwa chiyani magnesium oxide imagonjetsedwa ndi kutentha kwambiri? Kodi kutentha kwa magnesium oxide kumatha bwanji sintering? Kodi kutentha kwa sintering kwa magnesium oxide ndi kotani?

Magnesium oxide imadziwika kuti nthaka yowawa, kapena magnesia, ndi malo osungunuka a 2852 ° C, otentha a 3600 ° C, komanso kuchuluka kwake kwa 3.58 (25 ° C). Sungunuka mumchere wa asidi ndi amoniamu, wosungunuka ndi mowa. Magnesium oxide imakhala ndi zinthu zambiri zotsutsa komanso zoteteza. Ikhoza kusandulika kukhala makhiristo ikawotchedwa ndi kutentha kwakukulu pamwamba pa 1000 ° C. Ikafika mpaka 1500-2000 ° C, imakhala yakufa yopsereza magnesia (yotchedwanso magnesia) kapena sintered magnesia.

Kuyamba kwa Magnesium oxide:

Magnesium oxide (mankhwala amtundu: MgO) ndi magnesium oxide, ionic compound. Ndi yoyera yoyera kutentha. Magnesium oxide imapezeka mwachilengedwe ngati periclase ndipo ndi chinthu chopangira smelting ya magnesium.

Magnesium oxide imakhala ndi moto wothana kwambiri ndi zotchingira. Pambuyo powotchedwa ndi kutentha kwakukulu pamwamba pa 1000 ° C, imatha kusandulika kukhala makhiristo. Ikakwera kufika 1500-2000 ° C, imakhala yopsereza magnesia (yotchedwanso magnesia) kapena sintered magnesia.

Magnesium oxide mu Chingerezi ndi Magnesium oxide kapena Magnesium monooxid

Kodi okusayidi ya magnesium ndi chiyani?

Magnesium oxide imagawika m’magulu awiri: magnesia opepuka ndi magnesia olemera.

Kodi mawonekedwe a magnesium oxide ofunikira ndi otani?

Opepuka komanso okulirapo, ndi oyera amorphous ufa. Zopanda fungo, zopanda pake komanso zopanda poizoni.

Kodi kuchulukana kwa magnesium oxide wonyezimira ndi kotani? Kuchuluka kwake ndi 3.58g / cm3. Sasungunuka konse m’madzi oyera ndi zosungunulira, ndipo kusungunuka kwake m’madzi kumawonjezeka chifukwa chakupezeka kwa kaboni dayokisaidi. Itha kusungunuka mumchere wa asidi ndi ammonium. Imasandulika kukhala makhiristo itatha kutentha kwambiri. Pankhani ya carbon dioxide mlengalenga, magnesium carbonate mchere wambiri umapangidwa.

Nkhani yolemera ndiyophatikizika ndipo ndiyoyera kapena ufa wa beige. Ndiosavuta kuphatikiza ndi madzi, ndipo ndikosavuta kuyamwa chinyezi ndi kaboni dayokisaidi mumlengalenga. Ndikosavuta kusungunuka ndikulimba pothira mankhwala a magnesium chloride.
