Iibhili ezidadayo ziibhola ezingenanto ezithambileyo ezinomlotha oluhlaza okwesibhakabhaka ezinokudada phezu kwamanzi. Zimhlophe-ngwevu, zincinci kwaye zingenanto, kwaye zinobunzima obuphantsi. Ubuninzi bobuninzi yi-720kg/m3 (zinzima), 418.8kg/m3 (zikhanya), kwaye ubungakanani besuntswana bumalunga ne-0.1 mm, umphezulu uvaliwe kwaye uthambile, ubushushu buncinci, kwaye ukuchasana kungaphezulu kwe-1610℃. Ulwakhiwo lweebhili ezidadayo ikakhulu yi-silicon dioxide kunye ne-aluminium oxide. Ineempawu ezininzi ezifana neebhili ezicolekileyo, ezingenanto, ubunzima obulula, amandla aphezulu, ukumelana nokuguguleka, ukumelana nobushushu obuphezulu, ukugquma kobushushu, ukugquma kunye nokungatshisi ilangabi. Isetyenziswa kakhulu kwenye yezixhobo eziluhlaza kushishino lokuchasana.
