Use of borax solid wastes in diopside based glass-ceramic floor tile glazes

Abstract

Boron raw materials are amongst the most important natural sources for many industrial branches and their values become increasingly raised with the discovery of boron usage in many new technological fields. All the countries in the world are unfortunately not as lucky as Turkiye and USA where major boron deposits are mainly located. It is widely known fact that on one side, boron is very precious component with its technological importance, on the other; only its limited sources are available. Therefore, even its wastes have to be evaluated and regained. In the present work wastes of Etibor Kirka Borax Company of Turkiye were used in the production of opaque frits which was suitable for floor tile glazes. Standard and newly produced frit based glazes were applied on the pre-engobed floor tile bodies and single firing was employed. Final products were examined according to the certain standard tests and their microstructurcs were also investigated. All the results confirmed the evaluation of boron wastes in opaque floor tile glazes.
