Hanyar samar da masana'antu na silicon carbide mai amsawa-sintered yakamata ya kasance mai inganci

Hanyar samar da masana'antu na silicon carbide mai amsawa shine don fitar da yashi mai inganci mai inganci da coke mai calcined a cikin tanderun dumama lantarki. The mai ladabi silicon carbide tubalan an sanya su cikin kayayyaki tare da daban-daban barbashi size rarraba ta hanyar murkushe, karfi acid da alkali wanka, Magnetic rabuwa kayan aiki da nunawa ko ruwa rabuwa.

Silicon carbide yana da nau'ikan asali guda biyu na yau da kullun na siliki na siliki na siliki da silikon carbide kore, waɗanda duk na α-SiC ne. ① Black silicon carbide ya ƙunshi kusan 95% SiC, kuma ductility ya fi koren silicon carbide, yawancin waɗanda ake amfani da su don samarwa da sarrafa albarkatun ƙasa tare da ƙarancin ƙarfi, kamar gilashin laminated, ain, dutse, refractory, ƙarfe alade da karafa masu daraja. ② Green silicon carbide ya ƙunshi SiC game da 97% a sama, kaifin kai yana da kyau, yawancin su ana amfani da su don samarwa da sarrafa kayan aikin carbide, ƙarfe titanium da ruwan tabarau na gani, kuma ana amfani da su don honing layin silinda da goge babban sauri. kayan aikin karfe. Bugu da kari, akwai cubic mita na silicon carbide, wanda shi ne haske kore crystal yi da wani sabon tsari, kuma ana amfani da su samar da wani mold dace da qazanta super-finishing, wanda zai iya sa surface roughness daga Ra32 ~ 0.16μm wani aiki. da 0.04 ~ 0.02μm.

Babban amfani da martani sintering silicon carbide

(1) A matsayin abu mai jurewa lalacewa, ana iya amfani da shi azaman mold, kamar ƙafar yashi, dutsen dutse, dabaran niƙa, tayal ɗin yashi, da sauransu.

(2) A matsayin dioxidizing wakili da lalata resistant abu don karafa masana'antu. Silicon carbide ya ƙunshi manyan abubuwan amfani guda huɗu, waɗanda suka haɗa da: yumbu mai aiki, manyan kayan da ke jujjuyawa, kayan da ba za su iya jurewa ba da kuma narke albarkatun ƙasa. A wannan mataki, ana iya ba da siliki carbide roughage ta hanyoyi da yawa, wanda ba samfurin fasaha ba ne, kuma aikace-aikacen nano-silicon carbide foda tare da babban abun ciki na kimiyya da fasaha ba shi da wuya ya haifar da tasiri a cikin gajeren lokaci.

(3) high-tsarki guda crystal, dace da samar da semiconductor kayan, samar da silicon carbide sunadarai zaruruwa.

Iyakar aikace-aikace: Don 3-12 ƙafa sel photovoltaic, photovoltaic sel, potassium arsenide, ma'adini resonators da sauran line yankan. Solar photovoltaic masana'antu, semiconductor masana'antu, piezoelectric crystal masana'antu sarkar injiniya aikin albarkatun kasa sarrafa.

Sintering silicon carbide mai amsawa - dalilan samuwar

Matsakaicin matsananci da ma'aunin zafin jiki da aka samar a cikin tsakiyar ƙasa ana fesa shi daga ƙasa tare da lava. Kamar Thailand, Australia, Shandong na kasar Sin, Amurka da sauran kasashe. Karfe Jade yana samuwa ta hanyar taɓawa metamorphism. Kamar Myanmar, Kashmir, Anhui na kasar Sin da sauran yankuna. Rubies a duniya an samo su ne daga masu sanyawa. Yana da ta hanyar iri-iri na asali muhalli emeralds, blue duwatsu masu daraja ta yashwa tara dauki sintering silicon carbide da tsarki halitta silicon ore, carbon, itace slag, masana'antu gishiri kamar yadda m generated albarkatun kasa, a cikin wutar lantarki dumama tanderun dumama nuna tsara. Bugu da ƙari na katako na katako shine don yin ɗan ƙaramin abu mai gauraye a babban zafin jiki don samar da tsari mai laushi, wanda zai dace don nuna babban tururin jiki da kuma rashin daidaituwa wanda za a cire, don hana haɗarin fashewa, saboda tsararraki. na 1 ton na silicon carbide, na iya samar da kusan 1.4t na carbon monoxide (CO). Matsayin gishirin masana'antu (NaCl) yana da amfani don cire aluminum oxide, mahadi da sauran ragowar a cikin kayan.
