Abstract : The patent discloses a method for converting chrysotile asbestos to a magnesium hydroxide rich composition by subjecting the asbestos to repeated cycles of treatment with a 20 to 60 percent solution of potassium hydroxide heated to a temperature of from about 150C to 200C for a predetermined period of time, followed by the intermittent removal of the hot potassium hydroxide and subsequent washing of the treated asbestos between each cycle. The converted asbestos finds utility as a fuel cell matrix for hydrogen-oxygen fuel cells.
