Beredningsprocessen f\u00f6r reaktionsbunden kiselkarbid \u00e4r relativt enkel. denna typ av kiselkarbidkeramik anv\u00e4nder direkt kiselkarbid med en viss partikelstorleksf\u00f6rdelning, bildar embryon efter blandning med kol och f\u00f6rgasar sedan under h\u00f6g temperatur. En del av kisel reagerar med kol f\u00f6r att generera SiC, som kombineras med SIC i det ursprungliga embryot f\u00f6r att uppn\u00e5 syftet med sintring. Det finns tv\u00e5 f\u00f6rgasningsmetoder: en \u00e4r att n\u00e5 kiselns sm\u00e4lttemperatur, generera kiselns sm\u00e4lttemperatur och generera kisel\u00e5nga, Syftet med sintring uppn\u00e5s genom infiltration av kisel\u00e5nga i embryot. Produktionskostnaden f\u00f6r SiC-sintrad kropp framst\u00e4lld genom denna process \u00e4r l\u00e5g. Denna process best\u00e4mmer emellertid det kvarvarande fria kislet i det sintrade embryot. Denna del av kisel b\u00f6r ha en inverkan p\u00e5 till\u00e4mpningen av framtida produkter. \u00c5 ena sidan minskar den den sintrade kroppens h\u00e5llfasthet och slitstyrka, och \u00e5 andra sidan g\u00f6r f\u00f6rekomsten av fritt kisel kiselkarbid syrabest\u00e4ndig.<\/p>\n

Sintring av fri kiselkarbidkeramik: tryckl\u00f6s sintring av kiselkarbid kan delas in i sintring i fast fas och sintring i flytande fas. Renheten hos tryckl\u00f6s sintrad kiselkarbid \u00e4r h\u00f6g, inneh\u00e5llet av kiselkarbid \u00e4r mer \u00e4n 97%, syra- och alkalikorrosionsbest\u00e4ndigheten \u00e4r mycket b\u00e4ttre \u00e4n f\u00f6r reaktionssintrad kiselkarbid, och det \u00e4r l\u00e4tt att uppn\u00e5 batchproduktion.<\/p>\n

Varmpressningssintring av kiselkarbidkeramik \u00e4r ett av de mest effektiva s\u00e4tten att f\u00f6rbereda kiselkarbidkeramik med h\u00f6g densitet. Egenskaperna hos varmpressad kiselkarbid \u00e4r i allm\u00e4nhet h\u00f6gre \u00e4n egenskaperna hos reaktionssintrad och tryckl\u00f6s sintrad kiselkarbid, s\u00e4rskilt dess fina korn, h\u00f6g kompakthet och h\u00f6g h\u00e5llfasthet och h\u00e5rdhet hos produkter.<\/p>\n

H\u00f6g temperatur varm isostatisk pressning sintring kiselkarbidkeramik: H\u00f6g temperatur varm isostatisk pressning \u00e4r en avancerad keramisk sintringsprocess. Det keramiska pulvret eller det keramiska embryot packas och l\u00e4ggs i en het isostatisk pressanordning med h\u00f6g temperatur och sintras sedan till en t\u00e4t kropp under h\u00f6g temperatur och h\u00f6gt tryck. Det k\u00e4nnetecknas av samtidig och enhetlig trycks\u00e4ttning, kallad HIP.<\/p>\n

Omkristalliserad kiselkarbidkeramik: efter blandning, formning och torkning avfyras r\u00e5varorna i en luftisolerad elektrisk ugn med h\u00f6g temperatur vid 2300 ~ 2500 \u2103. N\u00e4r temperaturen \u00f6verstiger 2100 \u2103 kommer kiselkarbid att avdunsta och kondensera, vilket resulterar i bildandet av omkristalliserad kiselkarbidkeramik utan sintringskrympning och sj\u00e4lvbindande struktur.<\/p>\n
