| 中文摘要 | Thermal decomposition of NaNH4CrO4 . 2H(2)O was studied by means of thermogravimetric analysis (TG), differential thermogravimetric (DTG), differential thermal analysis (DTA) and X-ray diffraction (XRD). The results showed that the thermal decomposition of NaNH4CrO4 . 2H(2)O proceeds in three steps, i.e., the release of crystal water at temperature from 50 degreesC to 95 degreesC at first, the formation of the intermediates sodium chromate and ammonium dichromate with the partial release of ammonia at temperature from 100 degreesC to 180 degreesC, and the complete elimination of ammonia from 215 degreesC to 385 degreesC. In flowing ambient and suitable temperature(400 similar to 790 degreesC), the final decomposition product was mostly sodium dichromate. This leads to a cleaner process for sodium dichromate production. |
