Abstract
A solid heat-generating composition utilizing the heat of hydration of calcium oxide, comprising calcium oxide and a solid substance supplying water capable of reacting with calcium oxide such as a solid substance having water of absorption, adsorption or crystallization, and an organic compound which yields water by an intramolecular or intermolecular reaction at elevated temperature. The composition can be utilized in various applications utilizing heat generation, for example for thawing and heating frozen foods, controlled releasing of agricultural chemicals such as insecticides or repellents, warming human body, etc.
