Feature Ntawm Cov Hluav Taws Xob Hluav Taws Xob (Silicon Carbon Rods)
khoom ntiag tug
Kev ntxhib los mos: tawv thiab nkig, tiv taus kom txias thiab cua sov, tsis yooj yim deformed ntawm qhov kub thiab txias, thiab lwm yam khoom ntawm lub cev yog raws li nram no:
Thermal conductivity: 20 kcal / meter · teev · degree
Linear expansion coefficient: 5 × 10-6 (m / degree)
chemical khoom
Silicon carbon rods muaj tshuaj lom neeg ruaj khov thiab muaj zog acid tsis kam. Cov tshuaj alkaline muaj cov teebmeem corrosive rau nws nyob rau hauv qhov kub thiab txias.
Silicon carbon rod Cheebtsam tuaj yeem hnov mob nrog oxygen thiab dej vapor rau kev siv mus ntev tshaj 1000 degree raws li hauv qab no:
①Sic+2O2 → SiO2+CO2 ② Sic+4H2O=SiO2+4H2+CO2
Raws li qhov tshwm sim, SiO2 cov ntsiab lus hauv cov khoom maj mam nce, ua rau qeeb qeeb hauv kev tiv thaiv thiab kev laus. Yog tias muaj dej vapor ntau dhau lawm, nws yuav txhawb nqa oxidation ntawm SiC, thiab H2 tsim los ntawm ② cov tshuaj tiv thaiv yuav ua ke nrog O2 hauv huab cua los ua lub voj voog vicious. Txo cov khoom siv lub neej. Hydrogen (H2) tuaj yeem txo cov neeg kho tshuab lub zog ntawm cov khoom. Nitrogen (N2) qis dua 1200 degree tuaj yeem tiv thaiv SiC los ntawm oxidizing thiab reacting nrog SiC siab tshaj 1350 degree, cia SiC decompose chlorine (Cl2) thiab ua kom tiav cov decomposition ntawm SiC.
Feature ntawm Molybdenum Disilicide
Molybdenum disilicide hluav taws xob cua sov yog cov khoom cua kub raws li molybdenum disilicide (MoSi2), uas muaj cov yam ntxwv zoo xws li kub tsis kam, corrosion tsis kam, zoo airtightness, kub poob siab, thiab kev pab lub neej ntev. Nws tuaj yeem siv los ua cov khoom cua sov rau kev lag luam kub kub xws li ceramics, iav, metallurgy, hlau nplaum, thiab cov ntaub ntawv refractory.
Piv nrog rau cov cua kub ib txwm muaj, qhov tshwj xeeb zoo ntawm molybdenum disilicide cua sov cov ntsiab lus yog raws li nram no:
1) Kev siv kub yog siab. Nyob rau hauv ib puag ncig huab cua, kev siv kub ntawm 1700 hom tivthaiv yog 1700 degree, thiab kev siv kub ntawm 1800 hom tivthaiv yog 1800 degree, thiab nws tuaj yeem siv tau ntev.
2) Cov cua kub ceev tuaj yeem nce los ntawm chav sov mus rau qhov kub thiab txias siv rau kev ua haujlwm li ntawm ob peb teev, feem ntau yog vim qhov zoo thermal conductivity ntawm MoSi2.
3) Thaum qhov kub thiab txias, nws tsis yooj yim deformed lossis oxidized, feem ntau yog vim qhov me me thermal expansion coefficient ntawm MoSi2, thiab tsim cov SiO2 passivation txheej ntawm qhov kub thiab txias los tiv thaiv oxidation ntxiv.
4) Kev siv hluav taws xob tsawg, piv rau cov khoom siv cua sov xws li graphite electrodes, nws tuaj yeem txuag tau ntau dua 10% hluav taws xob, feem ntau yog vim qhov qis dua ntawm MoSi2, uas yog 2 × 10-5 Ω· cm.
