Silicon nitride hmoov muaj ntau yam siv. Raws li cov khoom siv tshiab hauv kev lag luam niaj hnub no, silicon nitride hmoov yog dav siv hauv ceramics, refractory, steel metallurgy, non-ferrous smelting, roj hmab thiab lwm yam lag luam.
Nyob rau hauv kev lag luam uas tsis yog-ferrous, nws muaj zoo heev corrosion kuj thiab wettability zog thiab yog dav siv. 2) Hauv kev lag luam steel,
A. Silicon nitride txheej tuaj yeem daws tau qhov teeb meem ntawm oxidation thiab kub kub thaum kho cua sov ntawm steel billets. Cov txiaj ntsig kev sim qhia tau hais tias nano-silicate antioxidant txheej tuaj yeem tiv thaiv oxidation los ntawm 3% -5% ntawm oxide nplai uas tsim los ntawm cov hlau kub-kuav los tiag rau 0.1% -0.8%, thiab txo 1% ntawm oxide nplai ua los ntawm stainless hlau kub dov daim hlau. {{10}}% oxide nplai poob qis dua 0.2%.
B. Silicon nitride phom av nkos. Cov phom av nplaum uas muaj silicon nitride yuav ua lub luag haujlwm zoo hauv kev ua kom sintering, corrosion resistance thiab anti-splitting. Thaum siv nyob rau hauv lub cub tawg lub cev los yog hluav taws xob rauv, nws muaj peev xwm kaw lub moj tej tawg rauv lub qhov ncauj ntau stably thiab yog heev yooj yim mus txiav.
C. Silicon nitride muaj cov ntawv thov zoo hauv HRB400 high-strength kub dov steel tuav. Si3N4 yog siv los ua tus neeg sawv cev ntxiv nitrogen, ua ke nrog FeV, los tsim V microalloyed Qib III steel tuav. Cov hlau tuav tau zoo heev thiab ruaj khov. Nws yog txheej txheem tshiab alloying rau kev tsim HRB400 Qib III steel tuav.
D. Silicon nitride yog thib ob tsuas yog boron nitride nyob rau hauv cov nqe lus ntawm nitrogen cov ntsiab lus nyob rau hauv ib chav tsev loj, thiab nws cov nqi yog tsawg, ua rau nws kim heev nyob rau hauv ntxiv nitrogen.
3) Vim tias cov khoom no muaj cov ntawv thov zoo hauv cov ceramics tshiab thiab cov ntaub ntawv sib xyaw, nws tuaj yeem txhim kho nws cov corrosion kuj, thermal conductivity, thermal shock resistance, hnav tsis kam, siab zog thiab lwm yam khoom.
