Si3N4
cev riser
Silicon nitride riser tubes muaj thermal shock kuj zoo heev thiab tuaj yeem tiv taus qhov kub thiab txias hloov (los ntawm chav tsev kub mus rau qhov kub ntawm molten aluminium) yam tsis muaj tawg. Silicon nitride muaj cov qauv ruaj khov thiab yuav tsis dhau theem kev hloov pauv lossis muag muag. Cov tshuaj reactivity ntawm silicon nitride riser hlab nrog molten txhuas yog tsawg heev. Lawv yuav tsis raug ntub los yog ua kom zoo los ntawm cov kua txhuas txhuas. Cov kua txhuas txhuas ntws zoo, tsis txhob txhaws thiab ua rau lub neej ua haujlwm ntev.
Si3N4
cev radiant
Thermal radiant tube yog ib qho khoom siv hluav taws xob tsis ncaj. Cov tam sim no dhau los ntawm kev tsim- nyob rau hauv cov cua kub tiv thaiv (feem ntau MoSi₂, silicon carbide rods los yog lwm yam siab - kub alloy hlau / strips) los ua kom sov. Silicon nitride ceramic raj yog siv los tiv thaiv lub tes tsho kom cais tawm cov cua sov los ntawm lub qhov cub cua sov (uas yuav ua rau corrosive, oxidizing, txo los yog xav tau siab purity). Thaum tshav kub kub hloov mus rau lub workpieces los yog cov ntaub ntawv nyob rau hauv lub cub tawg chamber los ntawm lub phab ntsa ntawm lub silicon nitride raj nyob rau hauv daim ntawv ntawm thermal tawg, ua tiav indirect cua sov.
Si3N4
ceramic rings
Silicon nitride ceramic rings yog siab -kev ua tau zoo thiab ntau-functional precision ceramic Cheebtsam. Nrog rau kev ua tau zoo ntawm cov khoom siv silicon nitride (Si₃N₄), lawv ua kom pom qhov txiaj ntsig tsis zoo hauv ntau qhov kev ua haujlwm hnyav. Nws cov qauv tsim qauv ua rau nws tsim tshwj xeeb rau cov ntawv thov tseem ceeb xws li sealing, bearing, rwb thaiv tsev, kev txhawb nqa thiab rwb thaiv tsev kub.
Al2TiO5
cev doz
Hauv kev lag luam ntawm high-kub kev lag luam, Quantitative Furnace Tube tshwj xeeb yog hais txog qhov siab -kub tiv thaiv tubular tivthaiv uas yuav tsum muaj kev tswj xyuas meej ntawm kev pabcuam lub neej, kev ua haujlwm tsis zoo lossis cov txheej txheem tsis zoo. Hom hluav taws xob lub raj no feem ntau siv rau hauv cov xwm txheej tseem ceeb uas yuav tsum muaj siab heev rau kev ntseeg siab, kev kwv yees lub neej thiab cov txheej txheem kev ruaj ntseg (xws li semiconductor, photovoltaic, thiab siab -kawg khoom sintering). Nws cov kev xaiv, kev saib xyuas thiab kev hloov pauv yuav tsum tau ua raws li kev txheeb xyuas cov ntaub ntawv ntau thiab kev kwv yees tus qauv.
Al2TiO5
cev riser
Nyob rau hauv lub tshav pob ntawm txhuas casting, txhuas titanate (Al₂TiO₅) riser hlab yog ib hom tshwj xeeb ceramic tivthaiv tshwj xeeb tsim los daws cov thermal shock tej yam kev mob. Lawv yog tshwj xeeb tshaj yog haum rau cov xwm txheej uas thermal shock resistance yog xav tau heev tab sis mechanical loads kuj tsawg. Nws lub ntsiab kom zoo dua yog nyob rau hauv nws zero coefficient ntawm thermal expansion, tab sis nws kuj tsis tshua muaj zog mechanical zog thiab complex sintering txheej txheem yuav tsum tau sib npaug.
Al2TiO5
Txhawb Nplhaib
Nyob rau hauv siab -kub kub pauv tshuab, Al₂TiO₅ Txhawb Lub Nplhaib ntawm aluminium titanate tshav kub exchangers yog ib qho tseem ceeb ntawm cov khoom tsim rau huab cua poob siab. Nws tus nqi tseem ceeb nyob rau hauv kev daws qhov teeb meem ntawm thermal stress cracking ntawm cov ntaub ntawv tsoos los ntawm zero coefficient ntawm thermal expansion (CTE). Nyob rau tib lub sijhawm, cov qauv tsim yuav tsum tau txais kev pom zoo raws li kev siv lub zog, kev tiv thaiv corrosion thiab ntev -lub sij hawm thermal stability
Al2TiO5
Lub tes tsho
Hauv kev tuag casting thiab lub ntiajteb txawj nqus casting, aluminium titanate rooj vag lub tes tsho (Al₂TiO₅ lub tes tsho) yog ib qho kev daws teeb meem tshiab rau cov teeb meem ntawm kev tawg ntawm cov tsoos hlau tes tsho uas tshwm sim los ntawm kev mob khaub thuas thiab kub. Nws cov txiaj ntsig tseem ceeb nyob hauv kev tshem tawm kev ntxhov siab tsis ua haujlwm nrog lub thermal expansion coefficient zero (CTE=1.0-1.8 × 10⁻⁶/K), thiab tib lub sijhawm, nws yog ib qho tsim nyog los daws qhov tsis txaus ntawm lub zog tsis muaj zog thiab tsis muaj zog tiv thaiv aluminium kua yaig los ntawm kev sib xyaw ua ke.
ZTA
ZTA
Zirconia Toughened Alumina (Zirconia toughened alumina, ZTA) ho txhim khu cov khoom tawg toughness thiab mechanical zog los ntawm dispersing zirconia (ZrO₂) particles rau hauv alumina (Al₂O₃) matrix, thaum tuav lub siab hardness, hnav tsis kam thiab tshuaj stability ntawm alumina.
