DEFINITION

Classification: 264/426

Producing or treating inorganic hydro-settable material (e.g., cement, plaster, etc.):

(under subclass 405) Processes wherein the energy directly applied is utilized for the treatment* of or formation of inorganic materials which are capable of being hydrolyzed by water to a solid state.

(1) Note. Inorganic hydro-settable material having minimal or trace amounts of organic material are properly classified here.

(2) Note. This subclass includes compositions made without any melting or fusion of particles, as well as those made by sintering, that is, a process in which a portion of a nonmetallic particle is bonded, coalesced, or partly fused to a portion of an adjacent particle due to the application of heat or heat and pressure.
