Babban ƙarfin lalacewa mai jurewa filastik refractorywani nau'i ne na kayan da ba a siffa ba wanda aka ƙera musamman don amfani da shi a cikin matsanancin zafin jiki, mai ƙazantawa, da yanayi mai ƙarfi. Yana da fasalin filastik mai ƙarfi, ingantaccen gini, ƙarfi mai ƙarfi, da kyakkyawan juriya, kuma ana amfani da shi sosai azaman rufin ciki don maɓalli na kayan zafi mai zafi a cikin masana'antu kamar wutar lantarki, ƙarfe, siminti, da injiniyan sinadarai. Tushen albarkatun ƙasa don ƙarfin ƙarfi da kayan filastik masu jurewa:
Aggregates da powders: High-alumina bauxite, corundum, silicon carbide, chromite yashi, da sauran kayan aiki masu wuyar lalacewa an zaɓi su don samar da kwarangwal na kayan, ƙayyade juriya da juriya na zafin jiki.
Masu ɗaure: Akwai na'urorin haɗi na hydraulic (kamar aluminate siminti) da kuma sinadarai (irin su phosphoric acid da phosphate), waɗanda za'a iya warkewa a cikin dakin da zafin jiki ba tare da zafi mai zafi ba.
Addmixtures: Ƙara masu rage ruwa, masu amfani da filastik, da ma'aikata masu hanawa don haɓaka aikin aiki da tsayin daka yayin gini; hada filayen karfe da filayen yumbu don inganta juriya mai tasiri da juriyar girgiza zafi.
Halayen ayyuka na kayan filastik mai ƙarfi mai ƙarfi:
"Plastic Refractory material":yana nufin abubuwan da ke da alaƙa waɗanda ke nuna kyawawan filastik a cikin ɗaki (mai kama da filastik), kuma ana iya gina su ta hanyoyi kamar ramming da sutura, ba tare da buƙatar girgiza don gyare-gyare ba.
"Babban ƙarfi da juriya": Ta hanyar ƙara daɗaɗɗen nau'i kamar corundum, silicon carbide (SiC), mullite, da high-alumina clinker, da kuma hada su da phosphate, calcium aluminate ciminti, ko Organic binders, yana samun babban ƙarfin matsawa a dakin da zafin jiki / high zafin jiki (≥60 MPa bayan bushewa a 110 ℃, 80 MPa) bayan bushewa a 110 ℃, 3 ≥ ℃ sawa juriya (asara ≤5 cm³, mafi mahimmanci fiye da na yau da kullun)
Babban bambanci tsakanin filastik mai ƙarfi mai ƙarfi da filastik na yau da kullun yana cikin:
