They may be as much as 96 gas by volume.
Structural ceramics examples.
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.
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.
Before sintering green bodies of ceramics include in their microstructure agglomerates impurities spatial variations of porosity and composition and preferred orientation of asymmetric particles.
For convenience ceramic products are usually divided into four sectors and these are shown below with some examples.
Earliest use of human ceramics for example in figurines of humans and other animals made of pottery discovered at dolní věstonice in the czech republic.
Engineering ceramics can be divided into functional ceramics and high strength structural ceramics.
Some ceramic foams are less brittle than their solid counterpart because air pockets may prevent cracks in the material from spreading.

Refractories such as kiln linings gas fire radiants steel and glass making crucibles.
Advanced structural ceramics are being used or have the potential to be used in a large variety of applications ferber and tennery 1991 american ceramic society website some of the primary application areas are listed in table 1 this is not intended as a complete list but rather a sampling of some of the applications with the greatest potential and or the greatest interest.
