A halin yanzu, akwai masana'antu da yawa don samar da samfuran Reaction Bonded SIC ga masana'antu daban-daban. Kamfanin Shandong Zhongpeng Special Ceramics Co., Ltd ya kamata ya zama ɗaya daga cikin mafi kyawun masu samar da samfuran Reaction Bonded SIC daban-daban, kamar Nozzle da sauransu a cikin wutar lantarki, yumbu, murhu, ƙarfe da ƙarfe, ma'adinai, kwal, alumina, man fetur, sinadarai, tsaftacewar ruwa, ƙera injina, da sauran masana'antu na musamman a duniya.

Za a iya raba SIC ɗin Reaction Bonded zuwasilicon carbide mai haɗin amsawakumasilicon carbide wanda aka samar da martani, bisa ga ko gurbin farko ya ƙunshi ƙwayoyin silicon carbide.

Silikon carbide mai haɗin amsawa

Carbide mai haɗin silicon carbide yana nufin tsarin samar da haɗin silicon carbide. A cikin yanayin da wurin farawa ya ƙunshi foda silicon carbide. A cikin tsarin amsawar, carbon da silicon suna amsawa don samar da sabon matakin silicon carbide kuma suna haɗuwa da ainihin silicon carbide. Tsarin shiri shine kamar haka, wanda shine hanyar da aka saba amfani da ita:

Haɗa foda na silicon carbide, foda na carbon da mahaɗin halitta;

Samar da cakuda busasshe kuma a cire shi daga haɗin;

A ƙarshe, samun carbide na silicon mai haɗin kai ta hanyar shigar silicon.

Wannan hanyar carbide mai haɗin kai da aka samar ta wannan hanyar gabaɗaya tana ɗauke da ƙwayoyin lu'ulu'u masu kauri da kuma yawan sinadarin silicon kyauta. Duk da haka, wannan hanyar tana da tsari mai sauƙi da araha. A halin yanzu,

Silicon carbide wanda aka samar da martani

Farawar farawar carbide mai siffar silicon carbide yana ɗauke da carbide kawai. Farawar farawar carbon mai ramuka ana yin ta ne da silicon ko silicon alloy don shirya kayan haɗin silicon carbide. Hucke ne ya fara ƙirƙiro wannan tsari. Hanyar Hucke kuma tana da nasa kurakuran. Tsarin shirya shi ya fi rikitarwa. Kudin wannan hanyar ya fi girma. A lokaci guda, yawan iskar gas yana tasowa yayin fashewar zafi. Wannan zai haifar da fashewar china cikin sauƙi. Saboda haka, wannan hanyar ta fi wahalar samar da manyan kayayyaki.

Idan aka kwatanta da sauran hanyoyin shiri na yumburan silicon carbide, hanyar haɗin amsawa tana da fa'idodi na musamman. A halin yanzu, binciken da aka yi a wannan fanni ya fi mayar da hankali kan nazarin tsarin sintering da kuma siffanta tsari da halayen samfuran. Duk da haka, binciken kan samar da babu komai ba shi da yawa. Kodayake akwai bincike da yawa kan tsarin amsawa a tsakaninsu, akwai ƙananan bincike kan motsin permeability, tsarin amsawa da kuma tsarin kayan aikin haɗa ƙarfe. Akwai ƙananan bincike kan shirya kayan da ke da halaye da tsari masu sarrafawa ta hanyar haɗakar shigar silicon da sauran kayan. Har yanzu ana buƙatar yin nazarin waɗannan fannoni.
