Vim li cas Purity Matters hauv Advanced Silicon Nitride Ceramics
Nyob rau hauv advanced ceramics, purity yog ncaj qha mus txuas raumicrostructural kev ncaj ncees thiab kev tswj tsis raug. Cov purity siab dua Si₃N₄ muaj tsawg dua cov pa impurities, metallic inclusions, thiab dawb silicon theem, uas ho txhim kho:
mechanical zog nyob rau hauv load
tsis kam mus tawg propagation
ntev -lub sij hawm thermal stability
qaug zog kuj nyob rau hauv rotating systems
Tsawg- qib purity (<95%) often contain more residual phases that reduce reliability under high stress or thermal cycling, making them unsuitable for precision engineering applications.
Kev ua haujlwm ntawm High -Purity Si₃N₄
High-purity silicon nitride ua tau zoo tshwj xeeb hauv ib puag ncig uas muaj xws li:
siab -kev sib hloov ceev
ceev thermal cycling
corrosive lossis reactive atmospheres
nruam mechanical stress
Qhov no yog vim li cas aerospace turbines, hybrid ceramic bearings, thiab precision mechanical seals cia siab rau yuav luag tshwj xeeb.Ntau dua lossis sib npaug li 99% Si₃N₄ cov ntaub ntawv.
Qib Sib piv ntawm Silicon Nitride rau Ceramics
Si₃N₄ 99% vs Si₃N₄ 95%

Si₃N₄ 95% yog tus nqi ntau dua- siv tau tab sis muaj qhov sib txawv me ntsis qis dua, ua rau nws tsim nyog rau kev lag luam ceramics es tsis yog siab - kawg daim ntawv thov.
Si₃N₄ 99.5% vs Si₃N₄ 97%
Si₃N₄ 99.5% yog tsim los rauib puag ncig kev ua tau zoo heev, muab superior thermal poob siab tsis kam thiab tsawg yam tsis xws luag.
Si₃N₄ 97% yog haum rau nruab nrab - mus rau - theem siab muaj ceramics qhov kev ua tau zoo yog qhov tseem ceeb tab sis tsis yog lub hom phiaj - tseem ceeb.
Si₃N₄ 99.9% vs Standard Industrial Qib
Si₃N₄ 99.9% sawv cev rau ultra- cov khoom siv purity siab siv hauvtxiav- ntug aerospace, semiconductor, thiab precision ceramic systems.
Cov qib kev lag luam Standard kuj tseem muaj cov kab mob tsis huv uas txwv ntev - lub sij hawm qaug zog tiv thaiv nyob rau hauv ultra- xav tau tej yam kev mob.
