A method was worked out and conditions established for the determination of the reaction rate of kaolinite dehydroxylation. The temperature dependence of the rate constant was determined experimentally; dehydroxylation of kaolinite can be considered a lst-order chemical reaction if the body thickness is 1 mm, the bod'ies have been preignited at 573 K and rapid changes in temperature are ensured both on heating up and cooling down the body.
