The investigation of some boron compounds in raw glaze

Our country that possesses %72 of the world?s boron reserves. Due to this reason the use of boron compounds in ceramics industry provides a great advantage respects. However, in which a raw glaze is used, the solubility of many common borates has meant that they have been discounted in spite of their potential benefits. Boron compounds use in ceramic glazes after fritted with the other components since borate compounds are water soluble and cannot be used in a wet process without undesirable effects appearing. Although the fritting process provides many advantages to using frits in glazes, enamels, but the process is expensive.In this study, we investigated use of boron compounds in the raw glaze without fritted. For this aim, the glaze recipe determined, the rheological properties optimized since boron compounds has negative effect on the rheological behaviour of raw glaze. An alternative routes to fritting process the raw glaze mixture calcinated at temperatures below the sintering temperature of mixture. The samples prepared using various glazing techniques subjected to heat in order to firing at laboratory and industrial scales and characterized by standard tests. Characterization results are analysed, the use of boron compounds in the raw glaze a little porosity occurred on the section of the glaze but don't contribute any negative effects on the technical properties of glaze.
