Khoom Description

Lub raj silicon carbide ceramic, feem ntau hu ua silicon carbide raj, SiC raj, los yog SiC ceramic raj, yog siab -kev ua tau zoo ntawm cov khoom siv ceramic. Nws feem ntau yog tsim los ntawm silicon carbide (SiC), tseem paub los ntawm cov npe xws li carborundum, carburo de silicio, carbure de silicium, lossis siliziumkarbid. Cov khoom no, nrog rau cov tshuaj muaj pes tsawg leeg ntawm SiC, muaj nyob rau hauv ntau hom xws li alpha silicon carbide thiab cubic silicon carbide. Lub raj yog tsim los ntawm cov txheej txheem siab heev xws li sintering silicon carbide (xws li sintering tsis muaj sintering, cov tshuaj tiv thaiv kev sib raug zoo silicon carbide, thiab recrystallized silicon carbide) los yog CVD SiC txheej, uas ua rau cov khoom muaj tshwj xeeb ntawm lub cev thiab tshuaj lom neeg. Paub txog nws cov khoom zoo ntawm silicon carbide-thermal, mechanical, thiab corrosion-resistant- nws yog dav siv thoob plaws ntau yam kev lag luam xav tau. Rau cov uas tab tom nrhiav yuav silicon carbide Cheebtsam, ntau silicon carbide lwm tus neeg thiab silicon carbide manufacturers, xws li Saint Gobain Ceramics, Morgan Advanced Ceramics, CoorsTek, thiab Nishimura Advanced Ceramics, muaj cov khoom xws li silicon carbide daim hlau, silicon carbide rods, thiab customize silicon.

Cov yam ntxwv ua haujlwm

Silicon carbide ceramic raj muaj qhov ua tau zoo heev -kub tsis kam, tswj cov qauv kev ruaj ntseg thiab lub zog nyob rau hauv ib puag ncig mus txog 1600 degree, ua rau nws yog ib qho tseem ceeb ultra- kub kub ceramic. Nws muaj cov thermal conductivity siab, tsis tshua muaj thermal expansion, thiab superior thermal shock kuj. Tsis tas li ntawd, nws muaj qhov zoo tshaj plaws hardness thiab hnav tsis kam, nrog rau muaj zog corrosion kuj rau acids, alkalis, thiab lwm yam corrosive media. Nws oxidation kuj thiab adjustable hluav taws xob conductivity (los ntawm insulating mus rau conductive) kuj yuav tailored. Lwm cov khoom tseem ceeb ntawm silicon carbide cov khoom muaj xws li kev ua haujlwm zoo heev ntawm cov khoom siv foob, ua rau nws zoo tagnrho rau silicon carbide bearings, bushings, thiab seals.

Qhov zoo thiab kev siv

Silicon carbide ceramic tubes tau siv dav hauv high -kub muaj qhov cub (rau sintering, annealing, thiab kev kho cua sov), ua hauj lwm raws li thermocouple tiv thaiv tubes, radiant tubes, burner nozzles, thiab cov khoom cua sov. Hauv kev lag luam chemical thiab metallurgical, lawv tau ua haujlwm nyob rau hauv siab -kub cov tshuaj tiv thaiv cov hlab ntsha, cov khoom siv hluav taws xob sib hloov, thiab cov kav dej rau kev tuav cov roj corrosive lossis cov hlau molten, feem ntau yog cov hauv ob sab phlu lossis refractory cib. Tsis tas li ntawd, lawv pom cov ntawv thov tseem ceeb hauv kev tsim khoom semiconductor (piv txwv li, CVD chambers, wafer ua), aerospace, kev tiv thaiv ib puag ncig (xws li, khib nyiab incineration), thiab cov khoom siv hluav taws xob (xws li hnub ci thermal Cheebtsam). Cov khoom lag luam tshwj xeeb suav nrog silicon carbide crucibles, nozzles, graphite-coated SiC qhov chaw, silicon carbide composites, thiab cov khoom siv rau cov tshuab foob thiab cov kabmob. Cov txheej txheem tsim khoom silicon carbide txhawb ntau yam ntawm cov ceramics siab heev rau kev siv thiab kev lag luam.
