Khoom piav qhia
Polynitrogen silane series khoom yog ternary (SiCN) ceramic precursors uas txawv ntawm binary (SiC) ceramic precursor polycarbosilane. Kev sib txawv ntawm cov ntsiab lus ua rau muaj kev sib txawv ntawm cov khoom sib txawv, thiab ntau hom kev sib xyaw ua rau muaj kev kub ntxhov siab. Cov khoom ntawm cov khoom siv polynitrogen silane ua los ntawm peb lub tuam txhab tam sim no tsuas yog cov khoom lag luam hauv Suav teb uas tau tsim ntau lawm.
Khoom ua haujlwm
Nws tsis tuaj yeem evaporate vim muaj zog hydrogen bonding ntawm molecules. Muaj peev xwm sib raug zoo nrog feem ntau cov substrates los tsim cov tshuaj bonds. Hauv qhov kub thiab txias ntawm 100-300 degree, kev sib txuas sib txuas tshwm sim ntawm cov molecules thiab tuaj yeem hloov mus rau hauv cov yas pob tshab. Nyob rau hauv qhov kub ntawm 400-700 degree, cov organic pawg ntawm cov molecules decompose, nrog rau kev khiav tawm ntawm me me hydrocarbon molecules, ammonia, thiab hydrogen. Nyob rau hauv qhov kub ntawm 700-1200 degree, peb-dimensional amorphous network qauv yog tsim, hu ua SiCN ceramic, nrog ib tug ceev ntawm ~ 2 g / cm3. Tshaj 1500 degree, Si3N4 / SiC siv lead ua theem yog tsim, nrog qhov ceev ntawm ~ 3g / cm3
Khoom siv:
1. Raws li ib tug precursor ntawm advanced ceramics, siv los npaj ceramic matrix composite cov ntaub ntawv, ceramic fibers, ceramic coatings, ceramic porous cov ntaub ntawv, thiab ceramic films;
2. Raws li cov organic resin, nws yog siv los npaj high-temperature-resistant, nplaim-retardant, high-strength engineering plastics thiab organic iav lub cev, thiab yog siv rau corrosion-resistant, anti-graffiti, thiab kev sib txhuam-resistant coatings;
3. Raws li cov nplaum nplaum, siv rau kev sib koom ua ke ntawm txhua yam khoom ntawm lawv tus kheej thiab ib leeg, suav nrog hlau, ceramics, iav, yas, roj hmab, ntoo, pob zeb, cement, fiber ntau, ntaub, thiab lwm yam;
4. Raws li cov ntaub ntawv ntxeem tau, npaj cov ntaub ntawv macroporous, mesoporous thiab microporous rau catalyst txhawb nqa thiab rwb thaiv tsev kub.
