Nei magnesium oxide isingashande kumatembiricha akakwirira? Ndeapi tembiricha inogona magnesium oxide kuwana sintering? Chii chiri sintering tembiricha ye magnesium oxide?

Magnesium oxide inowanzozivikanwa sevhu rinovava, kana magnesia, ine nzvimbo inonyungudika ye2852 ° C, nzvimbo yekubikira ye3600 ° C, uye huwandu hwehukama hwe3.58 (25 ° C). Inonyungudika muasidhi uye ammonium munyu mhinduro, isina insoluble mune doro. Magnesium oxide ine yakakwira dhigirii yekuratidzira uye inodzivirira zvivakwa. Inogona kushandurwa kuita makristasi mushure mekupiswa patembiricha yepamusoro pamusoro pe1000 ° C. Kana ichikwira kusvika pa1500-2000 ° C, inova yakafa yakatsva magnesia (inozivikanwawo semagnesia) kana sintered magnesia.

Nhanganyaya yeMagnesium oxide:

Magnesium oxide (kemikari fomula: MgO) ndeye magnesium oxide, ioniic komponi. Iyo chena yakasimba pakamuri tembiricha. Magnesium oxide iripo mune zvakasikwa muchimiro che periclase uye chinhu chakasvibirira chekunyungudutsa magnesium.

Magnesium oxide ine yakanyanya moto kuramba uye kuputira zvinhu. Mushure mekupiswa patembiricha yakakwira pamusoro pe1000 ° C, inogona kushandurwa kuita makristasi. Kana ikakwira kusvika pa1500-2000 ° C, inozove yakatsva magnesia (inozivikanwawo semagnesia) kana sintered magnesia.

Magnesium oxide muChirungu ndiyo Magnesium oxide kana Magnesium monooxid

Chii chinonzi magnesium oxides?

Magnesium oxide yakakamurwa kuita maviri marudzi: akareruka magnesia uye anorema magnesia.

Ndeapi maitiro echiedza chemagnesium oxide?

Yakareruka uye yakawanda, iyo chena amorphous upfu. Isinonhuwirira, isina kunaka uye isina chepfu.

Chii chinonzi kuwanda kwechiedza chemagnesium oxide? Kuwanda kuri 3.58g / cm3. Iyo haigadzike soluble mumvura yakachena uye organic manyoro, uye kusimba kwayo mumvura kunowedzera nekuda kwekuvapo kwekabhoni dhayokisaidhi. Inogona kuputswa muacid uye ammonium munyu mhinduro. Inoshandurwa kuita makristasi mushure mekushisa kwakanyanya kupisa. Kana iri kabhoni dhayokisaidhi iri mumhepo, magnesium kabhoni munyu munyu unoumbwa.

Iyo inorema nyaya iri compact mune vhoriyamu uye chena kana beige poda. Zviri nyore kusanganisa nemvura, uye zviri nyore kupinza hunyoro uye kabhoni dhayokisaamu mumhepo iri pachena. Zviri nyore kuomesa uye kuomesa kana ukasanganiswa nemagnesium chloride solution.
