Silicon Carbide (SiC) Powder Overview
Silicon carbide (SiC), inozivikanwawo secarborundum kana emery, ndechimwe chezvinhu zvakanyanya kushandiswa uye zvehupfumi. SiC inowanikwa mumhando mbiri: nhema silicon carbide uye green silicon carbide.
Production Process
SiC inogadzirwa nekunyungudutsa quartz jecha, petroleum coke, kana marasha tar, uye huni machipisi pakupisa kwakanyanya muchoto chekudzivirira. Green silicon carbide inogadzirwa zvakanyanya nekunyungudutsa yepamusoro-mhando silicon dioxide uye petroleum coke, nemunyu wakawedzerwa sechinhu chinowedzera.
Properties uye Applications
-Kuoma:Inowira pakati pecorundum nedhaimani.
-Mechanical Simba:Yakakwirira kupfuura corundum, brittle, uye inopinza.
-Conductivity:Iine mamwe magetsi uye thermal conductivity.
Nekuda kwezvivakwa izvi, SiC yakanakira maapplication anoda kusimba uye kudziya kwekutonga. Inoshandiswa zvakanyanya mumaindasitiri akadai seabrasives, refractories, uye semiconductors.
Zvimiro zveSilicon Carbide
1. Low Thermal Kuwedzera:Inoderedza shanduko muhukuru nekushanduka kwetembiricha.
2. High Thermal Conductivity:Zvinonyatsotamisa kupisa.
3. Thermal Stress Resistance:Inoderedza mukana wekushushikana kwekupisa.
4. Yakanakisa Thermal Shock Resistance:Inomira nekukurumidza kuchinja kwekushisa.
5. Corrosion Resistance:Durable kurwisa kukuvara kwemakemikari.
6. Kunyanya Kushivirira Kwekushisa: Inoita zvakanaka munzvimbo dzese dzinotonhora zvakanyanya uye dzinopisa.
7. High-Temperature Creep Resistance:Inochengetedza kugadzikana uye simba pakupisa kwakanyanya.
Semicera inogona kugadzirisa 4N-6N silicon carbide poda maererano nezvaunoda, unogamuchirwa kubvunza.
