Synthetic ceramic powders are preferred to natural ones where

  • A.a traditional appearance is the aim of the work
  • B.consistency and purity matter more than cost
  • C.the largest possible tonnage is what is required
  • D.the material has to be plastic when it is wet

Answer: B

Correct answer: consistency and purity matter more than cost

Synthetic powders are made to a specification - a stated purity, a controlled particle size distribution, a known phase - and they deliver it batch after batch. Where the property required depends on that control, as in a structural or electronic ceramic, the higher price is worth paying. Where it does not, it is not, as the next item says.
