They possess microscopic grain boundaries and microstructure pores. Generally strength and modulus go up and down together. Modulus e at 25c linearly related to melting temperature tm. Optical properties of ceramics6snell principal.

Advanced ceramics are fine particles in nature. Schaeffer is the editor of processing properties and applications of glass and optical materials published by wiley. Varshneya is the editor of processing properties and applications of glass and optical materials published by wiley. Definition advantage polycrystalline materials are solids that are comprised of a collection of crystallites grains separated from one another by areas of relative disorder known as grain boundaries.

Optical properties fine ceramics are sintered materials consisting of microscopic crystal particles separated by boundary elements. This chapter provides an overview on essential principle of optical properties of ceramics which involves the phenomena in physics of the interaction between light and materials. Fine ceramics can be made translucent by minimizing pores and boundary elements after sintering and by increasing crystal size in order to reduce boundary interfaces. Mechanical properties properties depend both on temperature and degree of crystallinity.

The assemblage of grains of various shapes and sizes together with the potential presence of porosity and secondary phases constitute the ceramic microstructure. The aim of this study is to demonstrate the superior optical and mechanical properties of a new class of submicron grain sized alumina ceramics relative to the current state of the art dental. This diffuses the light and it is difficult to transmit the light. Ceramics 30 350 gpa metals 50 200 gpa polymers 50 gpa 2.

Single crystals have no grain boundaries or pores hence light can easily pass through.
