ABSTRACT
AIM:To establish a new processing method for Borax with microwave technique. METHODS: A certain amount of Borax was placed into microwave oven and heated, and its weight loss was determined by electronic balance. The optimum processing parameters were obtained through orthogonal design. Water content of Calcined Borax was determined by far IR, microwave oven, and electric oven(at (400 ?C)),respectively. In addition, the stability of Calcined Borax was studied at room temperature. RESULTS: Calcined Borax will be available (within) 30 min with microwave treatment. The total water content can be determined by electric oven(at (400 ?C)). Calcined Borax should be powdered and packed as soosn as possible after processing. CONCLUSION: Microwave is a kind of excellent method for preparation of Calcined Borax in laboratory, with advantages of rapidness and simplicity.
