Abstract
| - In this work, ultramarine-like pigments were obtained in one step synthesis from NaA zeolite, sodium carbonate,and sulfur as precursors. To reduce the typical synthesis temperature (higher than 600 °C), sealed tubes wereused. Ultramarine-like pigments were successfully synthesized at temperatures lower than 400 °C. The ratioS/Na2CO3 was varied, and the percentage of sulfur/gram of zeolite remained constant.
