| Abstract: | The current situation in technics and prospect in application of barium nitrate are summarized. The technological process and action mechanism of preparing barium nitrate by the double decomposition using ammonium nitrate and barium sulfide as the raw materials are described. The test results indicate that the products come up to first grade of the national standard GB 1613 79 and the recovery more than 98%, being of a good economic benefit. |
