摘要

PPROBLEM TO BE SOLVED: To provide a negative ion generating raw material, its manufacturing method and a product using this negative ion generating raw material, capable of using blast furnace water residue slag for use with more environmental affinity. PSOLUTION: This negative ion generating raw material manufacturing method comprises a first step of crushing the blast furnace water residue slag at a low speed at the ordinary temperature, a second step of precipitating crushed powder in water in which a feeble current flows, a third step of transferring the precipitated blast furnace water residue slag to an ultrasonic zone after a predetermined first time passes, a fourth step of irradiating an ultrasonic wave for a predetermined second time to the blast furnace water residue slag transferred to the ultrasonic zone, a fifth step of drying the blast furnace water residue slag irradiated with the ultrasonic wave stepwise at the predetermined temperature while inserting an oxygen ion and a radon ion by an alumina ceramic kiln, and a sixth step of injecting the ion into the dried blast furnace water residue slag in a plasma chamber.
