Amaso adadayo ziibhola ezinomngxuma zothuthu ezinokuthi zidada phezu kwamanzi.Zingwevu-mhlophe, zibhityile kwaye azikho mgongxo, kwaye zikhaphukhaphu ngobunzima.Ubuninzi be-bulk 720kg / m3 (ubunzima), 418.8kg / m3 (ukukhanya), kunye nobukhulu be-particle malunga ne-0.1 mm, ubuso buvaliwe kwaye bugudileyo, ukuqhutyelwa kwe-thermal kuncinci, kunye ne-refractoriness ≥1610℃.Ukwakheka kweekhemikhali zamaso adadayo ikakhulu yisilicon dioxide kunye ne-aluminiyam oxide.Ineempawu ezininzi ezinje ngamasuntswana amahle, ihollow, ubunzima obulula, amandla aphezulu, ukumelana nokunxiba, ukumelana nobushushu obuphezulu, ukugqunywa kwe-thermal, ukugquma kunye ne-flame retardant.Isetyenziswa ngokubanzi kwenye yezixhobo ekrwada kushishino refractory.
