PURPOSE:A heat accumulating material comprising Na2SO4.10H2O, fumed silica, a nucleating agent and Na2SO4 and that separates no water even when the continuous melting-solidifying is repeated. CONSTITUTION:100pts.wt. Na2SO4.10H2O or its eutectic with another salt (e.g. NaCl) is blended with fumed silica (B), a nucleating agent (C) (e.g. Na2B4O7. 10H2O) and 2-45pts.wt. Na2SO4 (D). |
