Porous Ceramics Mechanical Properties

The following issues are of particular interest to this paper.

Porous ceramics mechanical properties.

There have been a number of different microstructures or architectures of highly porous ceramic and glass scaffolds that have been used for tissue engineering applications. Despite the large range in the reported mechanical properties of bone these act as a guide to the required mechanical properties of a scaffold. Therefore mechanical behavior of highly porous ceramics is different from that of dense ceramics. Journal of asian ceramic societies.

The influence of the relative porosity on the mechanical properties of porous ceramics has been largely described in the literature mainly in terms of elastic modulus and bending strength more seldom in compression. Regarding pore stress interactions there is strong evidence in the literature 40 41 42 concerning the mechanical behavior of human bones also a quasi brittle material to support the hypothesis that microstructural changes in material may be essential in controlling its. Mechanical and thermal properties of porous yttria stabilized zirconia. The mechanical properties of porous ceramics are greatly influenced by their microstructure.

However glassmaking involves several steps of the ceramic process and its mechanical properties are similar to ceramic materials. Then they take into account the mechanical properties of porous ceramics depend on pores stress interactions. Porous materials are commonly found in nature and as industrial materials such as wood carbon foams ceramics and bricks. Carefully tailored micro structure size morphology and orientation of grains and pores etc of porous ceramics has led to unique mechanical properties which cannot be attained even in the dense materials.

In order to use them effectively their mechanical properties must be. In this work we evaluate different mechanical testing methods such as static compression brazilian disc test and 3 point bending on their suitability for comparison of highly porous ceramic materials. Ceramics generally can withstand very high temperatures ranging from 1 000 c to 1 600 c 1 800 f to 3 000 f. Glass is often not considered a ceramic because of its amorphous noncrystalline character.
