Increasing the tableware glass quality by substituting CeO2 in place of Sb2O3

Abstract

Tableware glasses have extensively been used in daily lives. Not only functionality of tableware glass articles are significant but also aesthetic appearance take great importance. In this study, the increase in glass quality in terms of color aspects were worked. The goals are to improve glass quality, to increase aesthetically preferableness and to make cost effectiveness by adding cerium oxide in place of antimony trioxide in tableware glass articles of company. For that purpose, the addition of cerium oxide in pre-determined amounts was substituted for antimony trioxide to observe its effects on glass neutrality during real-time production activities had been continued in company. As a result of the study, with the addition of cerium oxide L* value was increased as 5.5%, the amount of zinc selenide and cobalt oxide decolorisation agents usage were decreased as 30% and 17%, respectively while 1% cost efficiency was achieved, and finally the purer, the sheerer and neutral tableware articles were obtained.
