Porous Ceramics Mechanical Properties

The mechanical properties of porous ceramics are greatly influenced by their microstructure.

Porous ceramics mechanical properties.

Therefore mechanical behavior of highly porous ceramics is different from that of dense ceramics. Ceramics generally can withstand very high temperatures ranging from 1 000 c to 1 600 c 1 800 f to 3 000 f. Various types of the sacrificial fugitives have been examined for obtaining well tuned shape and size of pores. Mechanical and thermal properties of porous yttria stabilized zirconia.

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. Glass is often not considered a ceramic because of its amorphous noncrystalline character. Then they take into account the mechanical properties of porous ceramics depend on pores stress interactions. 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.

Despite the large range in the reported mechanical properties of bone these act as a guide to the required mechanical properties of a scaffold. Porous ceramics have grown in importance in the industry recently because of their many applications like filters absorbers dust collectors thermal insulation hot gas collectors dielectric resonators bioreactors bone replacement and automobile engine components 1 2 3 4 generally porous ceramics have good properties such as mechanical strength abrasion resistance chemical and. Porous materials are commonly found in nature and as industrial materials such as wood carbon foams ceramics and bricks. The following issues are of particular interest to this paper.

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. However glassmaking involves several steps of the ceramic process and its mechanical properties are similar to ceramic materials. Journal of asian ceramic societies.
