In this research, the effects of temperature and duration of anorthite synthesis were examined by DTA, TGA, XRD, SEM and EDS analysis. Anorthite was synthesized with mixtures of kaolin and calcite powders with a weight ratio of 7 to 3, at three different temperatures of 1000, 1200 and 1400 °C, and three different synthesis times of 30, 180 and 300 min. Different phases in the raw materials mixture were formed during synthesis. These phases were investigated thoroughly to determine the role of time and temperature in their formation. Results proved that synthesis at 3 h and 1200 °C was suitable for the reactions of anorthite formation.

Abstract
In this research, the effects of temperature and duration of anorthite synthesis were examined by DTA, TGA, XRD, SEM and EDS analysis. Anorthite was synthesized with mixtures of kaolin and calcite powders with a weight ratio of 7 to 3, at three different temperatures of 1000, 1200 and 1400 °C, and three different synthesis times of 30, 180 and 300 min. Different phases in the raw materials mixture were formed during synthesis. These phases were investigated thoroughly to determine the role of time and temperature in their formation. Results proved that synthesis at 3 h and 1200 °C was suitable for the reactions of anorthite formation.| File | Dimensione | Formato | |
