Product Performance

1. Tin oxide ceramics

Tin dioxide yog ib hom n-hom semiconductor nrog finely dispersed dawb hmoov. Nws yog ib qho zoo heev pob tshab conductive khoom. Ob leeg muaj kev cia siab rau kev thov dav dav thiab tseem yog thawj cov khoom lag luam pob tshab conductive. Txhawm rau txhim kho lawv cov conductivity thiab stability hauv kev lag luam, lawv feem ntau doped. Piv txwv li, doping nrog cov ntsiab lus xws li Sb, V thiab Ni tuaj yeem ua rau cov conductivity nce ntxiv. Cov khoom siv ceramic raws li tin dioxide tsis yog tsuas yog muaj hluav taws xob zoo thiab qhov ntom ntom, tab sis kuj muaj qhov kub thiab txias tsis kam, siab kub re-softening point thiab corrosion kuj zoo heev, yog li Tin oxide ceramic qhov chaw tuaj yeem siv los ua cov khoom siv hluav taws xob rau kub kub. xws li crucibles, thermocouple tiv thaiv lub tes tsho thiab cov khoom siv tshuaj hauv ob sab phlu, thiab lwm yam.

2. Cov khoom ntawm SnO2 ceramics

Lub thermal expansion coefficient ntawm SnO2 ceramics yog me me (1/2 ntawm alumina ceramics), lub thermal conductivity yog siab, thiab thermal stability yog siab dua li ntawm alumina ceramics thiab zirconia ceramics. Lub volatilization tus nqi ntawm SnO2 ceramics yog tsawg ntawm 1400 degree, thiab volatilization muaj zog tshaj 1500 degree. Yog li, SnO2 ceramics tsuas yog siv tau rau hauv cov pa oxygen hauv qab 1500 degree.

Qhov tshwj xeeb kuj ntawm cov ntshiab SnO2 ceramics ntawm chav tsev kub yog 1010 ~ 1011Ω·cm. Txawm li cas los xij, ntxiv divalent lossis trivalent hlau oxides yuav txo nws cov kev tiv thaiv tshwj xeeb. Piv txwv li, tom qab ntxiv Sb2O3 thiab CuO, qhov tshwj xeeb tsis kam ntawm SnO2 raug txo los ntawm 7 mus rau 8 qhov kev txiav txim loj.

SnO2 ceramics muaj zog tiv thaiv kev yaig ntawm iav kua. Ntawm 1200 degree, qhov corrosion kuj ntawm SnO2 ceramic electrode rau calcium iav yog 1 ~ 2 npaug siab dua li ntawm fused corundum. Ntawm 1500 degree, alkali corrosion kuj yog 4 npaug siab dua li ntawm fused corundum. Nws kuj yog resistant rau corrosion los ntawm txhuas iav, arsenic iav, hlau iav, tooj liab iav.

3. Kev npaj ntawm SnO2 ceramics

Tin oxide ceramics feem ntau yog ua los ntawm SnO2, thiab cov ntsiab lus SnO2 yog kwv yees li 96 feem pua ​​​​rau 98 feem pua ​​​​, saib Table 1. Thaum npaj cov blanks, ib co additives yuav tsum tau ntxiv. Raws li cov kev xav tau sib txawv rau cov khoom ua tau zoo, cov khoom siv ntxiv tau muab faib ua ob pawg. Ib qho yog cov additives uas txhawb sintering. Cov additives xws li hlau oxides xws li kub, nyiaj, tooj liab, hlau, npib tsib xee, thiab zinc. Lwm qhov yog ib qho tshuaj ntxiv los txo qhov tsis kam, feem ntau yog oxides ntawm arsenic, antimony, tooj liab, uranium, strontium, niobium, thiab lwm yam. Cov nyiaj ntxiv yog txiav txim siab los ntawm kev ua tau zoo ntawm cov khoom, feem ntau 0.5 feem pua ​​​​rau 2 feem pua ​​(mas).

Table 1. Cov khoom xyaw ntxiv ntawm Tin oxide ceramic qhov chaw

Qhov kub ntawm refractory tsis qis dua 1900 degree, thiab nws muaj equiaxed tin dioxide hais nrog tus qauv kho qhov muag qhov loj ntawm 3 ~ 8μm. Kev sib sau feem ntau yog siv cov xovxwm qhuav lossis grouting. Tin oxide ceramics feem ntau raug rho tawm haujlwm hauv qhov chaw oxidizing ntawm qhov kub ntawm 1450 ~ 1500 degree. Qhov chaw nruab nrab ib puag ncig muaj kev cuam tshuam rau hluav taws xob conductivity ntawm SnO2 ceramics. Thaum cov pa oxygen ib feem siab siab, cov pa oxygen molecules yuav nkag mus rau hauv lub lattice ntawm cov khoom theem los tsim p-hom electron conduction; Thaum cov pa oxygen ib nrab siab qis, xws li hauv qhov chaw txo qis, cov siv lead ua lattice tsis muaj oxygen, thiab n-hom electrons yog generated Conductive. Feem ntau, SnO2 feem ntau yog ionically conductive.

Txhawm rau txhim kho cov hluav taws xob conductivity ntawm SnO2 ceramics ntawm chav tsev kub thiab kev ruaj ntseg ntawm hluav taws xob conductivity ntawm qhov sib txawv ntawm qhov kub thiab txias, cov txheej txheem ntawm kev kho roj theem thiab kev kho cua sov tuaj yeem siv tau. Gas theem kev kho mob yog siv cov volatilized vapor ntawm tin halide (xws li SnCl2, SnCl4, SnBrCl3, thiab lwm yam) thiab cov roj sib xyaw uas muaj cov pa dawb tso rau hauv qhov tob ntawm cov khoom los tsim cov khoom sib xyaw nrog cov khoom siv siab (xws li SnO) los yog cermets nyob rau hauv lub pores. . Kev kho cua sov yog ua kom sov cov tin oxide ceramics mus rau 1200 degree C thiab dhau hauv cov roj inert (xws li nitrogen, argon, thiab lwm yam) kom txo qhov kev tiv thaiv ntawm chav tsev kub los ntawm 6 mus rau 7 qhov kev txiav txim ntawm qhov loj. Kev hloov pauv ntawm lub tshuab nqus tsev yog zoo dua li ntawm cov roj inert.

4. Kev siv SnO2 ceramics
