  In this research, andalusite of Hamedan and other Iranian raw materials such as talc, kaolin, calcined alumina and magnesium oxide have been used for manufacturing of cordierite-mullite refractory materials. Different formulations were considered according to the chemical composition of raw materials. Then, raw materials were mixed, uniaxially pressed and after drying fired at different temperatures. Phase analysis (by XRD) and thermal expansion coefficient of fired samples were investigated. The results showed that Hamedan's andalusite can be used for the manufacturing of cordierite-mullite refractory materials. The optimum firing temperature range for cordierite and mullite phase formation is 1300-1350 ºC for 10 hrs. پرونده مقاله

  This study is conducted on the use of raw materials available in Yazd province in order to make monoprosa tile. For this reason, about one hundred various types of raw materials available in Yazd province have been studied and with regard to their chemical analysis, different bodies were made. Then, the most important properties such as density, shrinkage, green and fired strengths have been measured. Also, present phases in raw materials and the bodies were determined by x-ray diffraction method (XRD) and the thermal analysis of the samples was evaluated by dilatometry and simultaneously thermal analysis (STA). The results show that the properties of the tile samples made of the suitable raw materials in Yazd province and the tile bodies made in the Maryam tile factory are almost similar. The dilatometry and STA curves of both bodies are similar; hence, a good match between glaze used in the factory and tile samples can occur without any problem. پرونده مقاله
