B.S. Hemingway 1987 New heat-capacity data for quartz have been measured over the T interval 340-1000 K by differential scanning calorimetry. The data were combined with recent heat-content and heat-capacity data to provide a significantly revised set of thermodynamic properties for alpha -quartz and to resolve the problem of disparate heat-content and heat-capacity data for alpha - and beta -quartz.-J.A.Z. application/pdf en Quartz: heat capacities from 340 to 1000 K and revised values for the thermodynamic properties. article
