Sharaxaad Gaaban

Sintered Mullite waxaa lagu doortay bauxite-ta tayada sare leh ee dabiiciga ah, iyada oo loo marayo isku-soo-noqod heerar badan, oo la xisaabiyay in ka badan 1750 ℃. Waxaa lagu gartaa cufnaanta bulk sare, xasilloonida tayada xasilloon ee caabbinta shoogga kulaylka, index hoose ee gurguurta heerkulka sare iyo waxqabadka caabbinta daxalka kiimikada wanaagsan iyo wixii la mid ah.

Aad bay dhif u tahay qaabkeeda dabiiciga ah, mullite si macmal ah ayaa loo soo saaraa warshadaha iyadoo la dhalaalinayo ama la ridayo alumino-silicates kala duwan. Qalabka farsamada heerkulbeegga ee aadka u wanaagsan iyo xasiloonida ka dhalata mullite synthetic waxay ka dhigtaa qayb muhiim ah oo ka mid ah codsiyada dib-u-celinta iyo aasaaska.

Inkasta oo mullite ay u jirto sida macdanta dabiiciga ah, dhacdooyinka dabiiciga ah aad bay dhif u yihiin.

Warshaduhu waxay ku tiirsan yihiin mulliyada synthetic kuwaas oo lagu helo dhalaalid ama 'calcining' alumino-silicates kala duwan sida kaolin, dhoobo, dhif iyo silica wanaagsan iyo alumina heerkul sarreeya.

Mid ka mid ah ilaha ugu wanaagsan ee dabiiciga ah ee mullite waa kaolin (sida dhoobada kaolinic). Waxay ku habboon tahay soo saarista refractors sida leben la shiday ama aan la shidin, kabka iyo balaastiga isku dhafka ah.

Mullite-ka-soo-baxa ah iyo mullite-ka isku-dhafan ayaa ugu horreyn loo isticmaalaa soo-saarka refractories iyo tuurista birta iyo alwaaxyada titanium-ka.
