Reaction mixtures that include exothermic generating particles having a water soluble coating encasing a portion of the particles and, optionally an aqueous solution, and a buffer. The reaction mixtures are especially suited to generate heat in a controllable manner. In one such controlled reaction,...http://www.google.com.au/patents/US20030101984?utm_source=gb-gplus-sharePatent US20030101984 - Methods and reaction mixtures for controlling exothermic reactions
