Acquisition of a Rapid-Quench Cold-Seal Pressure Apparatus

小行星9526338 这笔赠款将提供16，610美元，作为购买设备所需费用的一半，以建造一个快速淬火，冷密封压力装置，用于在密歇根大学进行的实验岩石学研究。 具体而言，该系统将用于在低压（300 MPa）下合成含挥发物的硅酸盐液体。 然后这些样品将用于密度、热膨胀、粘度和热容的低温（1000摄氏度）测量。 还将使用含挥发物的硅酸盐液体进行现场密度（下沉/漂浮）和粘度（落球）实验。 这些实验将允许精确测定硅酸盐熔体中水和其他挥发物的偏摩尔体积。 ***

9526338 Lange This grant awards $16,610 as one-half of the costs of acquiring equipment necessary to construct a rapid-quench, cold-seal pressure apparatus for experimental petrological research to be conducted at the University of Michigan. Specifically, the system will be used to synthesize volatile-bearing silicate liquids at low pressures (300 MPa). These samples will then be used for low- temperature (1000 degrees C) measurements of density, thermal expansion, viscosity, and heat capacity. In situ density (sink/float) and viscosity (falling sphere) experiments will also be conducted using volatile-bearing silicate liquids. These experiments will allow precise determination of the partial molar volume of water and other volatiles in silicate melts. ***
