An agglomerate differs from an aggregate in that an agglomerate is

  • A.always larger than one millimetre across
  • B.held together weakly and can be broken by milling
  • C.a single crystal of the ceramic material
  • D.bonded so strongly that milling cannot separate it

Answer: B

Weak agglomerates are what dispersion and milling are meant to remove, whereas aggregates are bonded by sintering or chemical bridges and survive. The distinction matters because only one of them can be dealt with by processing.
