Erosion of Platinum Crucible in Melting Phosphate Glass
|
Abstract:
More accurately calculating the heat of formation and standard entropy of phosphate, andappliying thermodynanric first approximate equation, the authors analysed the melting proeessof phosphate glass. Oxygen and water existing in the system are the mAlN reason of Pt cruciblebeing eroded, and the erosive products Pt(PO3)2 and Pt(PO3)4 can easily react with free oxides,releasing Pt particles. POCl3 atmosphere introduced can either eliminate water and free oxides,or insulate air, so that Pt particles can be decreased.
