High microwave susceptibility of NaH{sub 2}PO{sub 4}{sm_bullet}2H{sub 2}O: Rapid synthesis of crystalline and glassy phosphates with NASICON-type chemistry
- Indian Institute of Science, Bangalore (India)
High microwave susceptibility of NaH{sub 2}PO{sub 4}{sm_bullet}2H{sub 2}O has been discovered. This hydrated acid phosphate of sodium can be heated upto 1000 K or more when exposed to 2.45 GHz microwaves. Using this, a novel microwave-assisted preparation of a number of important crystalline and glassy materials with NASICON-type chemistry has been accomplished in less than 8 min which is only a fraction of the time required for conventional synthetic procedures. The present single-shot approach to the preparation of phosphates is attractive in terms of its simplicity, rapidity, and general applicability. A {open_quotes}step-ladder{close_quotes} heating mechanism has been proposed to account for the high microwave absorbing ability of NaH{sub 2}PO{sub 4}{sm_bullet}2H{sub 2}O.
