摘要

本研究概述了对重铬酸钠、重铬酸钾、二钼酸钠、二钼酸钾、仲钨酸钠和仲钨酸钾的晶体学数据和热力学性质(包括固-固转变和熔融)的广泛调查。为了很好地了解文献中提供的数据,我们进行了全面的文献综述,并对从室温到熔点以上的温度进行了严格而全面的评估。这项工作是开发 Na+、K+//Cl-、SO42-、CO32-、CrO42-、Cr2O72-、MoO42-、Mo2O72-、WO42-、W2O72-、O2- 系统热力学模型的关键步骤之一,该模型与含有 O-H-S-Cl 和碱盐的大气中的高温腐蚀有关。

Critical Evaluation of the Thermodynamic Properties of Na2Cr2O7, K2Cr2O7, Na2Mo2O7, K2Mo2O7, Na2W2O7, and K2W2O7
This study outlines an extensive investigation of crystallographic data and thermodynamic properties (including solid-solid transition and fusion) for sodium dichromate, potassium dichromate, sodium dimolybdate, potassium dimolybdate, sodium ditungstate, and potassium ditungstate. A thorough literature review was conducted to obtain a good understanding of the data available in the literature, and a critical and complete evaluation has been performed from room temperature to above the melting temperatures. This work is one of the key steps towards the development of a thermodynamic model for the Na+, K+//Cl−, SO42−, CO32−, CrO42−, Cr2O72−, MoO42−, Mo2O72−, WO42−, W2O72−, O2− system, relevant for high temperature corrosion in atmospheres containing O–H–S–C–Cl and alkali salts.

期刊介绍: The Journal of Physical and Chemical Reference Data (JPCRD) is published by AIP Publishing for the U.S. Department of Commerce National Institute of Standards and Technology (NIST). The journal provides critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. Critical reviews may also be included if they document a reference database, review the data situation in a field, review reference-quality measurement techniques, or review data evaluation methods.
