Abstract: The present invention provides a water soluble, inorganic pyrolytic paint which, when dried to form a paint layer, generates heat from a whole surface of the paint layer by supplying electric current therethrough.

Abstract: The present invention discloses a method for preparing the inorganic hardenable slurry and the use of same in the solidification of wastes. In addition to water, the essential parts of the slurry are inorganic components including borates, cement-base powder and other additives such as magnesium oxide, gypsum and silica. The slurry is low in viscosity before solidification and flows freely,and within approximately 30 minutes after preparation the slurry becomes hardened into a highly solidified substance. The solidification of the slurry is resulted mainly from reaction of borates and the cement-base powder and to obtain a best result the weight of borates must be the same as that of the cement-base powder or even higher than the weight of the latter. The solidification mechanism differs entirely from the simple hydration reaction that brings about solidification of cement.The present invention also teaches a method for solidifying wastes with this hardenable slurry, i.e.
