Cov khoom tsim ntawm graphite crucible muaj qhov kub thiab txias tsis kam thiab tshuaj lom neeg ruaj khov. Nws tuaj yeem siv rau qhov kub thiab txias yam tsis muaj deformation lossis kev puas tsuaj vim qhov kub thiab txias. Nyob rau tib lub sijhawm, graphite crucible kuj muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv thaiv kev yaig ntawm ntau yam tshuaj lom neeg, yog li ua kom muaj kev tsim khoom zoo ntawm cov khoom siv semiconductor.

Dab tsi yog cov ntawv thov tseem ceeb ntawm graphite crucibles hauv semiconductor?

Hauv cov txheej txheem tsim khoom semiconductor,graphite cruciblesFeem ntau yog siv los nqa thiab tiv thaiv cov khoom siv hluav taws xob semiconductor, thiab tuaj yeem hloov cov cua sov thiab tam sim no zoo. Los ntawm tus kov thiab peb qhov ruaj khov brackets nyob rau hauv qab ntawm graphite crucible, ib tug loj tus naj npawb ntawm semiconductor Cheebtsam yuav muab tso rau hauv lub graphite crucible kom lawv nyob rau hauv zoo kev sib cuag nrog lub graphite crucible, yog li zoo hloov tshav kub thiab tam sim no.

Tsis tas li ntawd, graphite crucible kuj tseem siv tau los ua qhov zoo tshaj plaws thermal thiab hluav taws xob conductor. Vim nws cov thermal conductivity thiab hluav taws xob conductivity, graphite crucible tuaj yeem ua cua sov thiab tam sim no los ntawm sab nraud ntawm cov khoom siv mus rau cov khoom siv semiconductor hauv cov graphite crucible, yog li ua kom sov cov khoom siv hluav taws xob thiab tswj cov khoom tam sim no.

Tsis tas li ntawd, graphite crucible tseem tuaj yeem ua cov khoom siv hluav taws xob zoo tshaj plaws thiab cov khoom siv hluav taws xob, uas tuaj yeem ua raws li cov khoom siv hluav taws xob ntau, tso cai rau cov khoom siv los ua ntau yam khoom nyob rau tib lub sijhawm, yog li txhim kho kev ua haujlwm ntawm cov khoom siv.

Dab tsi yog cov ntawv thov ntawm graphite crucible hauv kev lag luam?

Qhov kub thiab txias stability thiab tshuaj stability ntawm graphite crucible pab kom nws tiv taus hlau smelting ntawm qhov kub thiab txias, kom ntseeg tau qhov zoo thiab stability ntawm cov khoom molten. Yog li ntawd, nws tuaj yeem siv los npaj thiab smelt ntau yam khoom siv hlau, xws li tooj liab, txhuas, zinc, thiab lwm yam. Tsis tas li ntawd, graphite crucible kuj siv tau los npaj thiab smelt alloy cov ntaub ntawv.

Tsis tas li ntawd, graphite crucibles kuj muaj qhov zoo corrosion kuj. Graphite muaj zog tiv thaiv corrosion rau feem ntau cov tshuaj lom neeg thiab tuaj yeem tiv thaiv kev yaig ntawm corrosive yam xws li acids, alkalis, thiab cov kuab tshuaj. Yog li ntawd, graphite crucibles feem ntau yog siv los khaws, lis, thiab tshuaj xyuas cov tshuaj corrosive. Piv txwv li, nyob rau hauv kev lag luam tshuaj, graphite crucibles yuav siv tau rau pickling kuaj, dissolving tshuaj, thiab khaws cia acidic reagents. Hauv cov organic synthesis, graphite crucibles tuaj yeem siv rau kev kho cov tshuaj tiv thaiv cov kuab tshuaj thiab cov catalysts, nrog rau cov txheej txheem crystallization thiab ziab ntawm cov organic tshuaj.

Cov ntsiab lus

Ntxiv nrog rau nws daim ntawv thov hauv kev tsim khoom semiconductor, graphite crucibles tuaj yeem ua lub luag haujlwm tseem ceeb hauv metallurgy, casting, machinery, chemistry thiab lwm yam haujlwm. Piv txwv li, hauv kev lag luam metallurgical, graphite crucibles tuaj yeem siv los yaj thiab ua kom zoo dua cov ntaub ntawv hlau; nyob rau hauv kev lag luam casting, graphite crucibles yuav siv tau los yaj cov ntaub ntawv hlau thiab ua ntau yam khoom hlau; Hauv kev lag luam tshuaj, graphite crucibles tuaj yeem siv los ua reactors lossis ntim rau tshuaj lom neeg. Yog li ntawd, tus nqi ntawm graphite crucibles tsis yog tsuas yog xav txog nyob rau hauv nws daim ntawv thov teb, tab sis kuj nyob rau hauv nws lub luag hauj lwm tseem ceeb nyob rau hauv industrial manufacturing.
