Silicon Carbide Nqaj
Cov khoom lag luam:
Kev tawm tsam-ua txhaum silicon carbide square beams yog siv rau cov kabmob-cov qauv qauv ntas ntawm qhov cub, lub qhov cub tawg, ob chav txheej menyuam lub qhov cub thiab lwm qhov chaw ncu. Cov khoom lag luam nyob rau hauv uas lub siab-qhov kub cov kabmob muaj peev xwm loj, tsis muaj khoov lossis deformation hauv kev siv lub sijhawm ntev, thiab kev pabcuam lub neej yog ob peb zaug ntawm lwm cov ntaub ntawv, yog li nws yog qhov zoo tshaj plaws kiln rooj tog rau huv porcelain thiab lwm yam kev lag luam hluav taws xob porcelain. Cov khoom lag luam yog nrog lub zog zoo kub hloov ua kom lub zog, thermal shock tsis kam, oxidation tsis kam thiab kev hloov kho dawb hauv kev siv ntev, yog li tuaj yeem txo qhov kev siv zog kom tsis muaj qhov hnyav ntawm lub tsheb kiln.
Cov cim kev ntsuas qhov tseem ceeb ntawm cov tshuaj tiv thaiv-sintered silicon carbide cov khoom
Yam ntxwv:
a.High qhov kub muaj zog ua rau lub zog hnyav thauj khoom
b.Txhais kev ua haujlwm siab thermal poob siab
c.High thermal conductivity
d.Txhais kev tiv thaiv oxidation kuj txhais tau lub neej ntev nyob rau hauv qhov kub ua haujlwm siab
Thov
Silicon nitride thiab silicon carbide kab teeb ci muaj qhov zoo tshaj qhov kub ua kom yuag, muaj zog tiv taus thiab oxidation tsis kam; siv dav hauv cov ntaub ntim kab mob tu cev, hluav taws xob muaj hluav taws xob zoo nkauj, lim dej, quartz tso rau saum npoo; tso cov paib thiab cov ntses uas muaj lub ntsej muag uas tau siv dav hauv kev siv ceramic kev lag luam txhua hnub; kev tiv thaiv raj siv rau kev ntsuas kub hauv ntau qhov kev lag luam; cov khoom tshwj xeeb zoo nkauj thiab lub tes tsho kub yog siv dav hauv ntau yam kiln thiab kev siv tshuab ua haujlwm.
