摘 要：研究了一种新的冶金多相化学平衡测定设备.它能在不改变系统平衡状态的情况下自动取样过滤,保证了测定数据的准确性.同时,可利用同一批试验测得不同反应条件下多个试验数据,利用此设备,成功地测定了在100～170℃范围内Na2WO4在NaOH－H2O中的溶解度,以及白钨矿用NaOH分解反应在100～150℃下的平衡常数.
Abstract: Anew device which can be used in measurement for chemical reaction equilibrium ofmetallurgical process at high temperature and high pressure was studied and manufactured.The filted test sample from the reaction container can be obtained automatically without anychange of the equilibrium conditions.Therefore the measured data are accurate. Likewise,more data in different test conditions can be obtained in one test batch.The solubilitv of Na2WO4 in NaOH-H2O at temperatures of l00～170℃ and the equilibrium constant of reaction for sheelite and NaOH are measured successfully by this equipment.
