Vpliv dodatkov CaO, ▫$Fe_2O_3$▫ in ▫$SiO_2$▫ na mineraloško sestavo taljenega korundaGrobelšek, IngridNa mednarodnem trgu se stalno povečujejo zahteve glede kakovosti korunda kot brusila ali abraziva. Zato v Tovarni dušika Ruše potekajo večletne raziskave, katerih cilj je izboljšati kakovost ... proizvedenega korunda. Pri raziskavah pogodbeno sodelujejo Kemijski institut Boris Kidrič s sodelavci Instituta za geologijo VTO Montanistika. Raziskave naj bi pokazale, kako vplivajo posamezne primesi na lastnosti električno taljenega korunda, zlasti še na njegovo trdoto. Moja diplomska naloga je del teh raziskav. V njej sem preiskovala vpliv različne količine dodanih oksidov Fe2O3, CaO in SiO2 na mineralno sestavo in mikrotrdoto električno taljenega korunda. Laboratorijsko pripravljene vzorce sem preiskovala z: rentgenskim difraktomerom, optičnim mikroskopom v odsevni svetlobi, elektronskim mikroanalizatorjem, Leitzovim merilnikom mikrotrdote in magnetnim merilnikom.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : I.
