Abstract
A phase change material is made by the process including the steps of providing a composition of a metal nitrate and water and adding tetraborate. This phase change material may be used in a heat battery.
Claims32
A heat battery made by the process including the steps of:
- providing a composition comprising a Group IA metal nitrate, a Group IIA metal nitrate and water;
- adding a tetraborate salt to form a phase change material to minimize acid formation and pressure buildup within the phase change material when sealed in a container;
- and
- placing the phase change material in a sealed container having a passage extending through the container and through which a heat exchange fluid may pass.
