Yashi Mai Girma
Bayanin Samfura
Yashi mai laushiabu ne mai hana ƙarfe silicate na aluminum, wanda galibi ana amfani da shi a tsarin simintin ƙarfe na bakin ƙarfe. Ƙarfinsa yana da kimanin digiri 1750. Mafi girman sinadarin aluminum a cikin yashi mai laushi, ƙarancin sinadarin ƙarfe, da kuma ƙaramin ƙurar, mafi kyawun ingancin samfurin yashi mai laushi. Ana yin yashi mai laushi ta hanyar yin amfani da sinadarin kaolin mai zafi sosai.
Siffofi:
1. Babban wurin narkewa, yawanci tsakanin 1750 da 1860°C.
2. Kyakkyawan kwanciyar hankali mai zafi.
3. Ƙarancin yawan faɗaɗa zafi.
4. Ingantaccen daidaiton sinadarai.
5. Rarraba girman barbashi mai ma'ana yana ba da damar zaɓi da daidaitawa bisa ga hanyoyin yin siminti daban-daban da buƙatun siminti.

Babban aikin simintin daidai shine kera harsashin mold (tsarin shafa tsarin kakin zuma da yadudduka da yawa na kayan da ba sa jurewa don ƙirƙirar harsashi na waje. Bayan tsarin kakin ya narke, ana samar da rami don zuba ƙarfe mai narke). Ana amfani da yashi mai laushi galibi a matsayin tarin da ba sa jurewa a cikin harsashin mold kuma ana amfani da shi akan layuka daban-daban na harsashin, musamman kamar haka:
1. Ƙwallon Sama (Yana ƙayyade Ingancin Filin Siminti kai tsaye)
Aiki:Layin saman yana da alaƙa kai tsaye da simintin kuma dole ne ya tabbatar da kammala saman da santsi (yana guje wa tsatsa da kuma ɓarna) yayin da kuma yake jure tasirin farko na ƙarfen da aka narke.
2. Bakin Baya (Yana Bada Ƙarfi da Numfashi Gabaɗaya)
Aiki:Bakin baya tsari ne mai matakai da yawa a wajen saman saman. Yana tallafawa ƙarfin harsashin mold gaba ɗaya (yana hana lalacewa ko rugujewa yayin zubarwa) yayin da yake tabbatar da iska (yana fitar da iskar gas daga ramin da kuma hana porosity a cikin simintin).
3. Aikace-aikace na musamman don yin simintin da ake buƙata sosai
Simintin ƙarfe mai yawan zafin jiki:kamar ruwan injinan jiragen sama (zafin da ke zuba daga 1500-1600°C), suna buƙatar harsashin mold don jure yanayin zafi mai tsanani. Yawan ƙarfin da yashi mai laushi na Mullite zai iya maye gurbin yashi mai tsada na zircon (wurin narkewa 2550°C, amma mai tsada), yana biyan buƙatun juriyar zafi mai yawa yayin da yake rage farashi.
Don simintin ƙarfe mai amsawa:kamar ƙarfe na aluminum da ƙarfe na magnesium (waɗanda suke da ƙarfin amsawa sosai kuma suna amsawa cikin sauƙi tare da SiO₂ a cikin yashi na quartz don samar da haɗakarwa), kwanciyar hankali na sinadarai na yashi na mullite na iya rage amsawa da hana samuwar "haɗakarwar iskar oxygen" a cikin simintin.
Don manyan simintin gyare-gyare masu daidaito:kamar gidajen akwatin gear na injin turbine na iska (wanda zai iya nauyin tan da yawa), harsashin mold yana buƙatar ƙarin ƙarfi na tsari. Tsarin bayan da mullite yashi da manne suka samar yana da ƙarfi sosai, yana rage haɗarin faɗaɗa mold da rugujewa.
4. Haɗawa da Sauran Kayan da ke Rage Ƙarfin Ruwa
A cikin ainihin samarwa, ana amfani da yashi mai laushi tare da wasu kayan aiki don inganta aikin harsashin mold:
Haɗuwa da yashi zircon:Ana amfani da yashi mai siffar zircon a matsayin saman (don tabbatar da cewa saman ya yi kyau) da kuma yashi mai siffar mullite a matsayin saman baya (don rage farashi). Wannan ya dace da simintin da ke da buƙatar saman sosai, kamar sassan sararin samaniya.
Haɗa shi da yashi mai siffar quartz:Don simintin da ke da ƙarancin buƙatun zafin jiki (kamar ƙarfe mai ƙarfe, wurin narkewa 1083℃), yana iya maye gurbin yashi mai siffar quartz kaɗan kuma yana amfani da ƙarancin faɗaɗa yashi mai siffar mullite don rage fashewar harsashi.
