Yadda za a zaɓi ɓangaren dumama na murhun muffle?

Abun dumama na murhun murfin gabaɗaya shine sandar carbide na silicon ko sandar molybdenum na silicon. Silicon molybdenum sanda resistive dumama kashi shine babban zafin zafin zafin jiki da kuma juriya na juriya mai zafi wanda aka yi akan molybdenum disilicide. Lokacin da aka yi amfani da shi a cikin yanayin iska mai ƙyalƙyali mai zafi, ana ƙirƙirar fim ɗin gilashi mai haske da ƙima (SiO2), wanda zai iya kare murfin ciki na sandan molybdenum na silicon daga hadawan abu da iskar shaka. Saboda haka, siliki molybdenum sanda kashi yana da musamman high-zazzabi hadawan abu da iskar shaka.

A cikin yanayin iska, matsakaicin zafin zafin aiki shine 1800 ° C. Rashin juriya na siliki molybdenum sanda mai dumama yana ƙaruwa cikin sauri tare da haɓaka zafin jiki, kuma ƙimar juriya ta tabbata lokacin da zafin jiki bai canza ba. A karkashin yanayi na al’ada, juriya na kashi baya canzawa tare da tsawon lokacin amfani. Sabili da haka, tsohuwar da sabon silicon molybdenum sanda za a iya gauraya abubuwan dumama wutar lantarki.

Dangane da tsarin, yanayin aiki da zazzabi na kayan aikin dumama, zaɓin madaidaicin nauyin kayan aikin wutar lantarki shine mabuɗin rayuwar sabis na siliki molybdenum sanda wutar lantarki.
