MgO是构成地球下地幔的主要矿物质之一，也是结构简单的最为稳定的氧化物之一，因此成为人们探索高温高压极端环境下材料物性的理想材料，也是人们认识更为复杂的氧化物和硅化物等地球组分的桥梁。本项目拟研究MgO及其含铁离子和铝离子MgO与MgSiO3矿物材料在冲击压加载条件下的物性，建立MgO微观结构与宏观物性的对应关系，从实验和理论两方面探讨力学性质、光吸收谱性质随压力的变化规律，探索MgO等离子晶体用作冲击波动态窗口材料的可能性，建立更为准确的热力学输运模型。 本项目研究可望从材料物理角度为高压科学以及地学提供数据和模型支持，加深人们对地幔演化以及炮轰过程的理解。

MgO is one of the major earth-forming minerals with a NaCl-type structure. A wide range of the NaCl-type structural stability suggests that MgO as an ideal pressure standard in high pressure experiments, as well as a linkage to understand the complicate oxides and silicides. This project intends to investigate MgO as will as Fe and Al ions doped MgO and MgSiO3 in shock wave experiments. It will construct the relation between the microscopic structure and the physical properties, the pressure dependence of mechanical and optical properties. The results will provide insights to the possibility of using the MgO as a window material in shock wave experiments, and build up a reliable thermal dynamical transport model. The proposed project will provide database and modeling to geography and high pressure science, improve the understanding on the earth evolution as well as the detonation physics.
