<p>Latent heat storage materials having enhanced fire-retardant properties include compositions of magnesia cement and a phase change material in which the magnesia cement is formed from magnesium oxide, magnesium chloride, and water. In particular, the molar ratio of magnesium chloride to water is in the range of about 1:11 to 1:15, and the molar ratio of magnesium chloride to magnesium oxide is in the range of about 1:1 to about 1:5. Also included are thermal storage compositions comprising a secondary binder and a phase change material, in which the secondary binder comprises dry inert powder, phosphogypsum, and an alkaline salt of any metal, and water. In further embodiments, the latent heat storage materials additionally comprise fillers, and/or intumescent agents. Processes for making these compositions are disclosed.</p> |
