Piezoelectric Crystal Cutting yog dab tsi?
Piezoelectric crystals, xws li quartz, lithium niobate, los yog PZT, yog dav siv nyob rau hauv electronics, sensors, thiab actuators. Txiav thiab polishing cov khoom siv lead ua no yuav tsum muaj kev ua haujlwm siab heev kom muaj qhov ruaj khov, qhov chaw tiaj tus, thiab kev ua haujlwm zoo.
Cov pa abrasives feem ntau ua rau micro- tawg, khawb, lossis qhov chaw tsis sib xws, txo cov txiaj ntsig thiab kev ntseeg siab ntawm cov khoom siv. Qhov no yog qhov uas silicon carbide (SiC) micropowder ua qhov tseem ceeb.
Vim li cas Silicon Carbide Micropowder yog qhov zoo tagnrho rau kev ua haujlwm piezoelectric
SiC micropowder muaj cov khoom tshwj xeeb uas ua rau nws zoo tagnrho rau kev txiav thiab polishing:
Siab Hardness (Mohs 9.2)- Tshem tawm cov khoom zoo yam tsis muaj deforming lub substrate.
Ntse Crystal Edges- Precise txiav nrog qhov tsawg kawg nkaus kev puas tsuaj.
Tswj Particle Loj- Ua kom lub ntsej muag zoo tib yam thiab polishing sib xws.
Tshuaj Inertness- Tsis txhob kis kab mob thaum ua haujlwm ntub dej.
Thermal stability- Txhim kho kev ua haujlwm tsis muaj degrading nyob rau hauv kev sib txhuam kub.
Cov yam tseem ceeb no ncaj qha ua rau kev txiav kom zoo dua qub, txo cov ntug chipping, thiab zoo tshaj qhov saum npoo.
Cov ntawv thov tseem ceeb hauv Piezoelectric Kev Lag Luam
Crystal Wafer Slicing- SiC micropowder tshem tawm hauv cov kua txiav tso cai siab -ceev, meej wafer txiav.
Nto Polishing- Ua tiav daim iav-zoo li ua tiav nrog roughness Tsawg dua lossis sib npaug rau Ra 0.2 μm.
Ntug tiv thaiv- Txo kev tawg thiab chipping txog li 40% piv rau cov pa abrasives.
Finishing rau Devices- Ua kom cov tuab tuab thiab ua haujlwm zoo piezoelectric.
Yuav ua li cas Particle Loj thiab Purity cuam tshuam kev ua haujlwm
Sub -micron SiC- Qhov tseem ceeb rau polishing zoo thiab daim iav tiav.
Micron - loj SiC- Zoo tagnrho rau kev txiav thiab ntxhib shaping ntawm wafers.
High purity SiC (Ntau dua lossis sib npaug li 99%)- Tiv thaiv kom tsis txhob muaj kab mob thiab tswj kev ua haujlwm ntawm hluav taws xob.
Xaiv cov qib zoo ua kom pom cov txiaj ntsig zoo thiab cov khoom siv piezoelectric zoo.
FAQ
1. Dab tsi ntawm piezoelectric crystals tuaj yeem ua SiC micropowder txheej txheem?
Quartz, lithium niobate, PZT, thiab lwm yam khoom siv hluav taws xob siv hauv hluav taws xob.
2. SiC txo cov ntug chipping li cas?
Nws cov npoo ntse ntse thiab tswj qhov loj me tshem tawm cov khoom kom huv si yam tsis muaj micro- tawg.
3. Dab tsi ntawm qhov roughness tuaj yeem ua tiav?
Txog li Ra 0.2 μm lossis zoo dua, haum rau cov khoom siv siab -precision.
4. SiC puas tuaj yeem siv los txiav cov kua dej?
Yog lawm, nws yog chemically inert thiab zoo tagnrho rau slurry -raws li txiav thiab polishing.
5. Vim li cas siab -purity SiC tseem ceeb?
Cov khoom paug tuaj yeem txo qhov kev ua tau zoo ntawm hluav taws xob thiab ua rau muaj qhov tsis xws ntawm cov khoom siv piezoelectric.
6. Puas yog ntsuab SiC lossis dub SiC zoo dua rau kev ua piezoelectric siv lead ua?
Green SiC yog qhov zoo dua vim muaj kev ua kom zoo dua qub thiab tawv tawv dua, kom ntseeg tau qhov tseeb thiab huv si.
