The present invention relates to a method by which a composition which will provide a foamed phosphate ceramic material is cast upon a support surface comprising regions having a substantially smooth character, being of relatively low surface energy, and having the ability to release from the cured phosphate material. In those regions where the smooth coating contacts the phosphate open cells will result, whereas in other regions closed cells will result. One preferred substrate against which the phosphate material can be cast is a wax material.

Process for preparing decorative foamed phosphate ceramic materials

A heat storage system which is comprised of calcium chloride hexahydrate as the storage medium and a nucleating agent, said nucleating agent being a mixture of dolomite and calcium hydroxide.

A novel process has been developed for the molecular-weight modification of polyphosphazenes. Poly(aryloxyphosphazenes) are thermally treated in an inert atmosphere or vacuum at temperatures from 100.degree. C. to 300.degree. C. so as to yield materials having reduced molecular weights, improved processability, and enhanced thermal stability.
