Significance and Importance of Thermal Expansion.
The U.S. Department of Energy's Office of Scientific and Technical Information.The material testing results showed that the elastic modulus and thermal conductivity of cordierite ceramics were one-and-a-half or more times higher than those of conventional low thermal expansion glass, while ensuring the thermal expansion coefficient roughly matching that of compared glass materials.Bailey and Yates (1967) determined the thermal expansion of crystals with CsC1 structure at low temperatures. Pathak and Vasavada (1992) and Pathak et al., (1973) reported the thermal expansion of four alkali halides at thigh temperatures by the x-ray method.
Covalent materials such as diamond, silicon carbide and silicon nitride have strong bonds between atoms, resulting in low coefficients of thermal expansion. In contrast, materials such as stainless steel possess weaker bonds between atoms, resulting in much higher coefficients of thermal expansion in comparison with Fine Ceramics.Related Topics.

Thermal expansion is where materials expand while being heated, causing them to take up more space. Some materials expand more than others - metals, for example, tend to expand a lot. But this all.
