Si₃N₄ Ceramic (Si₃N₄), Silicon Nitride Ceramic

Silicon nitride ceramics (Si₃N₄) yog cov ntaub ntawv siab melting point paub rau lawv qhov tshwj xeeb hardness thiab siab tshuaj inertness. Lawv muaj ib tug tsawg coefficient ntawm thermal expansion, siab thermal conductivity, thiab zoo heev thermal shock kuj. Tsis zoo li cov tsoos nkig ceramics, silicon nitride ceramics tuaj yeem tiv taus qhov cuam tshuam yam tsis yooj yim tawg. Lawv cov thermal expansion coefficient tsis tshua muaj kev ruaj ntseg zoo thaum lub sij hawm hloov kub ceev, tiv thaiv deformation thiab tawg. Cov ceramics muaj kev cuam tshuam zoo thiab lub zog. Cov ntawv thov feem ntau suav nrog cov khoom siv ceramic, thauj khoom-cov kabmob hooks, nrhiav tus pins, thiab cov raj ceramic.
Specifications thiab qhov ntev: Kev ua haujlwm tuaj yeem ua raws li cov duab kos lossis cov qauv.

Silicon nitride ceramics (Si₃N₄) yog siab -cov ntaub ntawv zoo tshaj plaws ceramics uas muaj ntau yam zoo heev. Tsis zoo li qhov brittleness ntawm cov tsoos ceramics, lawv cov qauv sab hauv tshwj xeeb zoo cuam tshuam kev ntxhov siab nyob rau hauv qhov tseem ceeb sab nraud, tiv thaiv kev puas tsuaj sai. Qhov no ua rau lawv indispensable nyob rau hauv kev tsim cov khoom tseem ceeb rau aerospace thiab automotive engines uas yuav tsum tau tiv taus siab loads thiab cuam tshuam.
