Corundum da mullite tubalin an yi su da tsattsarkan corundum da mullite azaman kayan albarkatu, wanda aka ƙera su ta babban matsin lamba kuma aka ƙone su a babban zafin jiki. Samfurin yana da halayen juriya mai zafi, juriya na lalata, juriya na oxyidation, kwanciyar hankali mai ɗorewa, da ƙarancin canjin layi.

Bayani na tubalin mullite na corundum:

1. Kaya mai nauyi yana da ƙanƙanta mai ƙarfi, ƙarfin ƙarfi mai ƙarfi, juriya ga gas masu lalata iri -iri, kwanciyar hankali mai ɗorewa mai ɗorewa, kyakkyawan yanayin ɗorewar zafi, da sa juriya.

2. Kaya masu nauyi suna da tsari iri ɗaya na ciki, babban ƙarfin matsawa, juriya mai lalata, juriya na girgiza, juriya na oxyidation, zafin sabis mai ƙarancin ƙarfi da ƙarancin yanayin zafi.
