  • Method of preventing explosions using a smelt water explosion inhibitor
    Patent number: 4106978
    Abstract: A method of preventing a physical explosion caused by the contact of water with a molten material such as molten smelt and molten metal by the addition of a porous, high surface area powder which is coated with an anti-wetting agent. The material sinks through the water layer to the interface between the water and the molten material carrying air or gas bubbles with it.
