I-silicon carbide powder eluhlaza kanye ne-silicon carbide micropowder

I-Silicon carbide (SiC), eyaziwa nangokuthi i-carborundum, i-semiconductor equkethe i-silicon ne-carbon enefomula yamakhemikhali i-SiC. Kwenzeka emvelweni njenge-mineral moissanite engavamile kakhulu. I-synthetic silicon carbide powder iye yakhiqizwa ngobuningi kusukela ngo-1893 ukuze isetshenziswe njenge-abrasive. Izinhlamvu ze-silicon carbide zingahlanganiswa ndawonye ngokucwilisa ukuze zenze izitsha zobumba eziqine kakhulu ezisetshenziswa kakhulu ezinhlelweni ezidinga ukubekezela okuphezulu, njengamabhuleki emoto, ama-clutch emoto namapuleti e-ceramic kumavesti angangenwa izinhlamvu. Ukusetshenziswa kwe-elekthronikhi kwe-silicon carbide okufana nama-light-emitting diode (ama-LED) kanye nezitholi kumarediyo okuqala aboniswa okokuqala cishe ngo-1907. I-SiC isetshenziswa kumadivayisi kagesi we-semiconductor asebenza emazingeni okushisa aphezulu noma ama-voltage aphezulu, noma kokubili. Amakristalu awodwa amakhulu e-silicon carbide angatshalwa ngendlela ye-Lely; zingasikwa zibe amagugu aziwa ngokuthi i-synthetic moissanite. I-silicon carbide enendawo ephezulu ingakhiqizwa ku-SiO2 equkethwe ezintweni zezitshalo.

Incazelo Yomkhiqizo

I-Shandong Zhongpeng Special Ceramics Co., Ltd ingesinye sezixazululo ezintsha ze-silicon carbide zobumba eChina. I-ceramic yobuchwepheshe ye-SiC: Ubulukhuni be-Moh buyi-9 (ukuqina kwe-Moh entsha yi-13), enokumelana okuhle nokuguguleka nokugqwala, ukuhuzuka okuhle kakhulu – ukumelana ne-oxidation. Impilo yesevisi yomkhiqizo we-SiC iyinde izikhathi ezi-4 kuya kwezi-5 kune-alumina material engu-92%. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi. Inqubo yekhotheshini iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ingeyesibili. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisele izinhliziyo zethu emphakathini.
