Si3N4 Ceramic

Silicon nitride (Si3N4) ceramic yog cov khoom siv zoo tshaj plaws ceramic paub txog nws cov khoom tshwj xeeb, thermal, thiab tshuaj lom neeg. Nws yog tsim los ntawm silicon (Si) thiab nitrogen (N) atoms thiab yog tsim los ntawm ntau txoj kev tsim khoom, suav nrog kev kub siab, kev sib koom ua ke, thiab sintering.

Cov khoom ntawm Si3N4 ceramic

1. Siab zog
Silicon nitride ceramics muaj lub zog zoo heev, ua rau lawv tsim nyog rau cov ntawv thov uas yuav tsum tau muaj peev xwm thauj khoom siab.

2. Zoo heev Hardness
Si3N4 ceramics yog ib qho nyuaj heev, ze rau ntawm pob zeb diamond. Cov cuab yeej no ua kom lawv tsis kam hnav thiab puas.

3. Superior Thermal stability
Cov ceramics tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj qhov poob ntawm lub zog, uas yog qhov tseem ceeb hauv cov ntawv thov uas muaj cua sov heev.

4. Tsawg Thermal Expansion
Silicon nitride muaj cov coefficient tsawg ntawm thermal expansion, txhais tau tias nws muaj kev hloov pauv me me nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias.

5. Zoo thermal conductivity
Thaum tsis zoo li cov hlau, Si3N4 ceramics muaj cov thermal conductivity ntau dua piv rau lwm cov ntaub ntawv ceramic. Qhov no ua rau lawv muaj txiaj ntsig zoo hauv cov ntawv thov uas cov cua kub dissipation tseem ceeb heev.

6. Tshuaj Inertness
Silicon nitride tiv taus tshuaj lom neeg los ntawm feem ntau cov tshuaj corrosive, ua kom muaj kev ruaj ntseg hauv qhov chaw hnyav.

7. Hluav taws xob rwb thaiv tsev
Si3N4 ceramics yog cov khoom siv hluav taws xob zoo heev, uas muaj txiaj ntsig zoo hauv ntau yam khoom siv hluav taws xob thiab khoom siv hluav taws xob.

Kev siv ntawm Si3N4 ceramic

1. Cov cuab yeej txiav
Vim nws hardness thiab hnav tsis kam, Si3N4 yog siv rau hauv kev tsim cov cuab yeej txiav rau kev siv machining.

2. Bearings thiab Rollers
Silicon nitride bearings thiab rollers pom cov ntawv thov nyob rau hauv qhov kub thiab txias qhov twg cov pa steel bearings yuav ua tsis tiav.

3. Turbine Cheebtsam
Si3N4 ceramics yog siv rau hauv cov roj turbines thiab cov cav tov vim lawv qhov kub thiab txias tsis kam thiab txhua yam muaj zog.

4. Ballistic Armor
Silicon nitride kev sib xyaw ua ke ntawm hardness thiab lub teeb yuag ua rau nws haum rau lub cev armor thiab cov ntaub ntawv tiv thaiv.

5. Cov khoom siv semiconductor
Si3N4 yog siv rau hauv kev lag luam semiconductor rau cov khoom xws li wafer tuav pins thiab susceptors.

6. Biomedical Applications
Hauv qee yam khoom siv kho mob thiab kev cog qoob loo, silicon nitride yog siv vim nws cov biocompatibility thiab tiv thaiv corrosion.

7. Molten Hlau tuav
Silicon nitride yog ua hauj lwm nyob rau hauv cov ntaub ntawv foundry li crucibles thiab lwm yam khoom siv los tuav molten hlau.

Zuag qhia tag nrho, Si3N4 ceramic qhov tshwj xeeb kev sib xyaw ua ke ntawm cov khoom ua rau nws muaj txiaj ntsig zoo hauv ntau qhov kev lag luam thiab kev siv qhov chaw ua haujlwm hauv qhov hnyav hnyav lossis qhov kub siab yuav tsum tau ua.
