Colloidal stability-slip casting behavior relationship in slurry of mullite synthesized by the USP method
This study presents the outcome of a research concerning the relationship between the colloidal stability of mullite powders synthesized by the USP (ultrasonic spray pyrolysis) method and its slip casting behavior. The ... -
Effect of colemanite on properties of traditional mullite zirconia composite
In this study, mullite zirconia composites are synthesized via reaction sintering method by using zircon, kaolinite and alumina mixtures including colemanite (Ca2B6O115H2O) (7 wt.%). In mullite zirconia composites, the ... -
Fabrication of beta-cristobalite porous material from diatomite with some impurities
The room temperature stabilized ß-cristobalite ceramic has great potential to use in production of engineering ceramic materials due to its high resistance to thermal shock and low expansion coefficient with high chemical ... -
Mineralogical and physicochemical properties of talc from Emirdag, Afyonkarahisar, Turkey
Lens-shaped talc deposits related to Mesozoic gabbroic rocks are exposed in an area of 2 km2, about 80 km northwest of Afyonkarahisar (western Anatolia). Different alteration zones in talc deposits were determined depending ... -
Preparation of cordierite ceramics from talc with boron oxide addition
Gören R.; Mergen A.; Ceylantekin R. (2004)Thermal reactions of impure materials of talc, silica and alumina with moderate particle sizes were investigated to obtain a dense cordierite ceramic by boron oxide addition as a sintering aid. Mixed powders were uniaxially ... -
Purification of diatomite powder by acid leaching for use in fabrication of porous ceramics
This study presents an investigation of the purification of a raw diatomite by acid leaching conducted in hot solution (75 °C and 5 M HCl) for long periods up to 240 h, evaluates the use of these purified powders in the ... -
Rapid synthesis of mullite powders
This study covers the synthesis of high purity mullite powders using ultrasonic spray pyrolysis and the microstructural evaluation of bulk materials prepared by using this powder. Tetraethylorthosilicate and aluminum nitrate ... -
Sintering of zinc metatitanate with zinc borate addition
The rapid progress in mobile and satellite communication systems has increased the demand for the development of dielectric materials for microwave frequencies. Zinc titanates have possible application as microwave resonator. ...
