Temperature-induced coalescence and @DT07618@ of porous solid particles below the @M03821@ points of their major components.
Notes:
  1. The term was originally coined for the process by which fly ash produced in combustion of fuels such as coal is baked at a very high temperature. The sintered material is used in the manufacture of cinder blocks and other @CT07540@ products.
  2. Modified from previous definition. The definition proposed here is recommended as being more explicit.
