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. ***

这笔拨款将提供16,610美元，作为在密歇根大学进行岩石学实验研究所需的快速淬火冷密封压力装置所需设备的一半费用。具体来说，该系统将用于在低压（300 MPa）下合成含挥发物的硅酸盐液体。然后将这些样品用于低温（1000摄氏度）测量密度，热膨胀，粘度和热容量。现场密度（沉/浮）和粘度（落球）实验也将使用含挥发性硅酸盐液体进行。这些实验可以精确地测定硅酸盐熔体中水和其他挥发物的部分摩尔体积。＊＊＊
