خبير الاتصال2011年1月21日 The thermo-elastic behavior of a natural epidote [Ca1.925 Fe0.745Al2.265Ti0.004Si3.037O12(OH)] has been investigated up to 1,200 K (at 0.0001 GPa) and 10 GPa (at 298 K) by means of in situ synchrotron powder diffraction. No phase transition has been observed within the temperature and pressure range investigated. P–V data fitted with a
خبير الاتصال2021年4月19日 Most minerals are solid at room temperature, a fundamental characteristic that distinguishes them from non-metals and metals, which might exist in different states based on the environmental conditions. This solid state is a critical physical property, emphasizing the stability and distinct structure of minerals. ...
