Class Information
Number: 264/434
Name: Plastic and nonmetallic article shaping or treating: processes > Direct application of electrical or wave energy to work (e.g., electromagnetic wave, particulate, magnetic, induction heat, sonic, electrostatic energy, etc.) > Producing or treating inorganic material, not as pigments, conductive enhancers, or fillers (e.g., ceramic, refractory material, etc.) > Including vitrifying or sintering (e.g., fusing, firing, burning, etc.)
Description: Processes wherein the inorganic material thereof is subjected to temperatures sufficiently high (with or without pressure) which causes said material to, at least partially, coalesce or fuse.
