nano-silicon nitride / nano Si3N4 20nm 99.9%
Cov yam ntxwv tseem ceeb ntawmnano-silicon nitride ultrafine silicon nitride hmoov npaj los ntawm txoj kev txheej txheem tshwj xeeb, purity siab, me me particle loj, faib, thaj chaw loj, kev ua haujlwm ntawm qhov chaw, tsawg bulk density, UV reflection tus nqi ntawm 95% thiab nqus ntawm infrared absorption tus nqi saum toj no 97%, lub cuab yeej mus rau hauv porcelain qis kub, zoo dimensional stability, siab mechanical zog, tsis kam rau tshuaj corrosion, kub siab zog, thiab tus kheej-lubricating nyhuv hauv composite nyob rau hauv kev tsim ntawm fine dispersed theem, yog li zoo heev txhim kho tag nrho kev ua tau zoo ntawm composite. Nws cov khoom nrog tus kheej-lubricating zog, tuaj yeem siv rau cov roj. Lub hardness siab ntawm silicon nitride, tus coefficient ntawm sliding friction yam ntxwv tuaj yeem siv rau ntawm cov hlau nto ntawm ceramic hnav-resistant composite coatings, thov rau cov coatings tuaj yeem ua si hnav-resistant thiab cov kuab tshuaj yam ntxwv, siab-purity silicon nitride tuaj yeem siv rau hauv ib tug quartz crucible tso tus neeg sawv cev nrog.
1. Kev tsim cov khoom siv hauv tsev: xws li lub pob thiab cov menyuam ntawm cov kabmob dov siv hauv kev lag luam hlau, tshuaj lom neeg, tshuab, aviation, aerospace thiab lub zog, cov kabmob tiaj tus, tes tsho, valve, thiab hnav, tiv taus kub siab, tiv taus corrosion xav tau rau cov khoom siv hauv tsev. rocket nozzles, missile nrog nozzle;
2. Kev kho cov hlau thiab lwm yam khoom siv: xws li pwm, cov cuab yeej txiav, cov hniav turbine, turbine rotor thiab lub tog raj kheej phab ntsa txheej alloy;
3. cov ntaub ntawv sib xyaw: cov hlau, cov khoom siv av nplaum, thiab cov khoom sib xyaw ua los ntawm graphite, roj hmab, yas, tshuaj pleev xim, cov nplaum thiab lwm yam khoom sib xyaw ua los ntawm polymer;
4. hnav cov yeeb yaj kiab nanoparticle uas siv rau lub xov tooj ntawm tes, lub tsheb thiab lwm yam kev tiv thaiv nto, txheej tiv taus hnav, cov xim pleev xim electrophoresis, ua si zoo heev.
