Abstract

Volume–temperature pressure expansivity for nanomaterials have been determined using second-order bulk modulus, volume and temperature dependence of pressure derivative equations of state. The expansion has been theoretically examined from second-order bulk modulus pressure–volume and temperature expansion by a modified version of our previous model. The nanomaterials viz., ε-Fe, α-Fe₂O₃, γ-Al₂O₃ and γ-Si₃N₄ are used to verify this model and compared with other Equation of state, and experimental data are reported in the literature.

纳米材料的二阶体模与热膨胀系数

纳米材料的体积-温度压力膨胀率是利用二阶体积模量、体积和温度依赖性压力导数状态方程确定的。根据二阶体积模量压力-体积和温度膨胀率，我们利用先前模型的改进版对膨胀率进行了理论研究。ε-Fe、α-Fe2O3、γ-Al2O3 和 γ-Si3N4 等纳米材料被用来验证该模型，并与其他状态方程进行了比较，文献中也报告了实验数据。

期刊介绍： The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
