1. Kev siv kub kub
Rauv cua sov cov ntsiab lus: MoSi2 tuaj yeem siv rau cov khoom cua sov hauv qhov cub kub.
Nws qhov kub tuaj yeem ncav cuag 1800 ° C.
Yog li ntawd, nws yog qhov tsim nyog rau cov txheej txheem uas yuav tsum tau tswj qhov kub thiab txias thiab kub stability.
Industrial processing: Nws tuaj yeem siv rau hauv cov txheej txheem metallurgical complex.
Cov txheej txheem no suav nrog sintering, debinding thiab hlau txhaj tshuaj molding.
Nws ua kom cov txheej txheem kawg-rau-kawg efficiency.
2. Tshuaj stability thiab kuj
Oxidation kuj: MoSi2 tsim ib txheej tiv thaiv ntawm SiO2 ntawm nws qhov chaw ntawm qhov kub thiab txias.
Qhov no tiv thaiv oxidation ntxiv.
Nws tuaj yeem siv tsis tu ncua rau ntau txhiab teev hauv huab cua ntawm 1700 ° C yam tsis muaj kev puas tsuaj.
Corrosion tsis kam: Nws tiv taus corrosion los ntawm cov hlau molten thiab slag.
Nws tsis cuam tshuam los ntawm HF, aqua regia thiab lwm yam inorganic acids.
Txawm li cas los xij, nws yog soluble hauv kev sib xyaw ntawm nitric acid thiab hydrofluoric acid.
3. Mechanical thiab lub cev muaj zog
Brittleness thiab lub zog: Txawm tias nyuaj thiab nkig, MoSi2 muaj lub zog compressive txog li 2310MPa.
Qhov no muaj txiaj ntsig zoo rau kev siv cov txheej txheem hauv qhov chaw kub kub.
Thermal conductivity thiab hluav taws xob khoom: zoo thermal conductivity thiab hluav taws xob conductivity ua rau nws haum rau kub kub ntsiab thiab thermocouples.
4. Kev tsim khoom thiab kev sib txuas
Cov txheej txheem synthesis: MoSi2 yog tsim los ntawm cov tshuaj tiv thaiv ncaj qha ntawm molybdenum thiab silicon hmoov ntawm qhov kub thiab txias.
Feem ntau nqa tawm hauv ib puag ncig hydrogen.
Kev tsim khoom siv tshuab: Nws tuaj yeem tsim los ntawm txoj kev txias nias sintering thiab kub nias sintering txoj kev.
Cov tom kawg tuaj yeem txhim kho txhua yam muaj zog.
