Q: The type of ceramic material that is capable of withstanding high temperature, resists chemical action, and does not lose its physical shape is :
  • A. glass
  • B. clay bricks
  • C. tiles
  • D. refractory
Correct Answer: Option D - Refractory– (i) These materials are capable of withstanding high temperature in different industrial process. (ii) These are able to resist the chemical action of the material being heated and withstand the mechanical load. (iii) They have high dimensioned and chemical stability and do not lose their physical shape and chemical composition. (iv) Refractories are good thermal insulators and have low electrical conductivity.
