摘要

PURPOSE: To form Bi₅O₇(NO₃) by performing heat decomposition of Bi(NO₃)₃.5H₂ O by heating and ending the heat-decomposition before changing to Bi₂O₃. ;CONSTITUTION: When Bi(NO₃)₃.5H₂O is heated at 400-450°C for a specified time, it is heat-decomposed in accordance with chemical equation I ((S) is a solid; ↑ is a base body), and H₂O and NO are released and then the Bi₅O₇(NO₃) having an orthorhombic structure is obtained. The temp. is further raised to proceed the heat decomposition then it reacts in accordance with a chemical equation II to form Bi₂O₃. The Bi₅O₇(NO₃) is expected for the applications such as the treatment of atomic power generation waste liquid or industrial waste liquid, absorption and fixation of harmful ions in gas and absorption and removal of them.;COPYRIGHT: (C)1994,JPO&Japio
