They may be as much as 96 gas by volume.
Structural ceramics examples.
Some ceramic foams are less brittle than their solid counterpart because air pockets may prevent cracks in the material from spreading.
For convenience ceramic products are usually divided into four sectors and these are shown below with some examples.
Ceramic tiles are being made in india and mesopotamia.
Before sintering green bodies of ceramics include in their microstructure agglomerates impurities spatial variations of porosity and composition and preferred orientation of asymmetric particles.
Examples of structural ceramics are refractory ceramics such as alumina al 2 o 3 which are used as crucibles silicon nitride ceramics used as cutting tools and cordierite mullite refractories used for their good thermal shock behaviour.

A brief history of ceramics.
Refractories such as kiln linings gas fire radiants steel and glass making crucibles.
Advanced structural ceramics ceramic materials that demonstrate enhanced mechanical properties under demanding conditions.
Because they serve as structural members often being subjected to mechanical loading they are given the name structural ceramics ordinarily for structural applications ceramics tend to be expensive replacements for other materials such as metals polymers and composites.
Structural including bricks pipes floor and roof tiles.
Engineering ceramics can be divided into functional ceramics and high strength structural ceramics.
