Fabricating Porous Ceramics
Porous ceramics have several advantageous features of low thermal conductivity, small heat mass, great specific surface area, hardness, good wearability, and resistance to high temperatures and corrosion, as well as good permeability for open-cell bodies.
Answer:
Porous ceramics are used to manufacture the flame arrester, and the proper design of this kind of arrester can avoid these problems, as well as early damage in service.
Explanation:
1.
Good chemical stability. Choosing the appropriate material species and techniques can make porous products suitable for various corrosive conditions in which the products are expected to function.
2.
Great specific strength and rigidity. The shape and size of pores in porous ceramics will not change under gas pressure, liquid pressure, and other stress loadings.
3.
Fine thermal stability. Porous products made of heat-resistant ceramics can filtrate molten steel or high-temperature burning gas.
