Abstract
A method and apparatus is disclosed for the production, delivery and control of microscopic quantities of minute solid carbon dioxide (CO2) particles having uniform density and distribution for use in a CO2 Composite Spray process, which employs compression of liquid carbon dioxide to form a supersaturated liquid, which is then condensed via micro-capillaries into minute and highly energetic solid carbon dioxide particles, which are injected into a propellant gas stream.
