- Opis:
- Boric oxide has an important place in glaze technology and is the second most important network-former after silica. Lower thermal expansion coefficient; higherchemical and mechanical durability; good glaze appearance are some of the benefits of boric oxide. In wall tile production; generally transparent frits with 1-7% boric oxide are used to obtain glossy transparent glaze. It can be said that boric acid is the fourth expensive raw material in frit production after zirconium, zinc oxide and potassium carbonate due to its high cost limits its usage in frit production. The aim of this study is to investigate colemanite (CaB₃O₄(OH)₃·H₂O) mineral usage in transparent frit production instead of using boric acid. To achieve this aim, four different frit mixtures Std, K.1, K.2 and K.3 with 0 wt.%, 3 wt.%, 6.5 wt.% and 11.5 wt.% colemanite content were prepared respectively. For comparison of the thermal behavior of frits, hot stage microscope was used. It was observed that, all of the samples prepared with colemanite have lower sintering and softening temperatures than the standard recipe because of its high earth alkaline oxide content. The obtained glazes were characterized by X-ray diffraction, dilatometer, Harcourt and Autoclave tests.
