Dab tsi yog qhov tiv taus ntawm Mosi2? Cov yam ntxwv tseem ceeb thiab cov ntawv thov piav qhia

Molybdenum disaticide (Mosi2) yog cov khoom siv uas ua ke cov khoom ntawm cov khoom siv cua sov thiab cov khoom siv hluav taws xob tsis kam lees yog 134 μω-CM ntawm kwv yees li 830℃ntsuas hauv nyias cov yeeb yaj kiab {{{} Tus nqi no qhia nws cov kev siv hluav taws xob, uas yog qhov ntsuas kub thiab lwm yam kev kub ntxhov hauv kev siv cua sov.

Cov Ntsiab Lus Tseem Ceeb:
Dab tsi yog qhov tiv taus ntawm Mosi2? Cov yam ntxwv tseem ceeb thiab cov ntawv thov piav qhia
Resistivity ntawm Mosi2:

Kev tiv thaiv molybdenum disilide (Mosi2) yog 134 μXE ntsuas rau cov ntawv qhia yooj yim rau cov khoom siv high .
Resistivity yog tus tseem ceeb ntsuas rau cov ntaub ntawv siv hauv cov khoom cua kub vim tias nws txiav txim siab hloov kho hluav taws xob rau hauv tshav kub {}}
Cov khoom siv ntawm Mosi2:

Mosi2 Mosi2 muaj cov khoom ntawm ob qho ceramics (e . pa hluav taws xob, thermal conductivity, thermal conductivity).
Nws melting point ntawm 2030℃ua rau nws haum rau cov kev siv kub siab kub.
Nws oxidation tsis kam yog vim kev tsim ntawm kev tiv thaiv silicon dioxide txheej thiab tso cai rau kev ua haujlwm siab, uas tiv thaiv kev ua haujlwm ntawm huab cua sov txog 1700℃hauv huab cua.
Cov ntawv thov ntawm silicon dioxide:

Mosi2 tau dav siv los ua cua sov hauv kev lag luam xws li iav tsim khoom, confamic Sinchanes, thiab cua sov diffusion rurgaces {}}
Nws cov yam ntxwv tsis tshua muaj qhov zoo-kub yam ntxwv ua rau nws zoo rau cov kev ua tau zoo nyob hauv ib puag ncig qhov kub thiab txias.
Cov kev sib tw thiab kev saib xyuas:

Mosi2 yog nkig thiab nquag rau cov neeg kho tshuab tsis ua haujlwm thaum lub tsev kawm ntawv kom haum thiab siv los txo cov kev pheej hmoo no.
Txawm hais tias nws siab dua brittleness, nws thermal poob siab tsis kam thiab ntev kev pabcuam lub neej ua nws cov ntaub ntawv kub kom haum rau cov ntawv thov kub siab kub {}}
Piv nrog rau lwm cov ntaub ntawv:

Piv rau tungsten disilide (WSI2), uas muaj kev tiv thaiv 93}} Tsis tas li cas los xij, tsis muaj qhov ntau dua rau cov ntawv thov kub siab dua {}}
Ib puag ncig thiab tshuaj tiv thaiv:

Mosi2 tiv thaiv kev tawm tsam los ntawm molten cov hlau thiab sawb, nrog rau cov kua qaub huv si acid thiab} Txawm li cas los xij, nws yog zoo li Molten Alkalis.
Nws oxidation thiab corrosion resistance ua kom muaj kev ua siab ntev nyob rau hauv ib puag ncig hnyav tsis muaj chaw.
Los ntawm kev nkag siab cov ntsiab lus no, cov neeg yuav khoom siv thiab cov ntaub ntawv muaj peev xwm ua tau kev txiav txim siab Mosi2 yog tsim nyog rau lawv cov ntawv thov puas yog, tshwj xeeb yog cov pa taws thiab oxidizing ib puag ncig {}}
