Answer
For refractory ceramic materials, the three characteristics that improve with increasing porosity are as follows:
1. decreased thermal expansion and contraction upon thermal cycling
2. improved thermal insulation
3. improved resistance to thermal shock.
The two characteristics that are adversely affected are as follows:
1. load-bearing capacity
2. resistance to attack by corrosive materials
