Abstract
A new heat sink composition having relatively high volumetric heat capacity and relatively high density have been prepared. The compositions comprise a set of formulas including: a) 50-95% oxide of iron and 50-5% of a mixture of clay, an organic binder or an inorganic binder, where said mixture can contain any portion of clay, organic binder or inorganic binder in any proportions provided the mixture adheres to the 50-5% compositional range; b) 15-95% oxide of iron and 85-5% of clay; c) 15-85% oxide of iron, 10-2% of a transition metal oxide other than iron and 75-13% inorganic binder; and d) 50-80% oxide of iron, 15-5% of talc and 35-15% clay. The compositions show good dried and fired properties and can even be loaded and fired in-situ because they possess good dried crush strength.
