Question

lndicate the crystal which have low co-efficent of expansion​

Answer 1

Coefficient of Thermal Expansion

Covalent materials such as diamond, silicon carbide and silicon nitride have strong bonds between atoms, resulting in low coefficients of thermal expansion.

good night to all of you mates

Answer 2

Answer:

When materials are heated, their size and volume increase in small increments, in a phenomenon known as thermal expansion. Expansion values vary depending on the material being heated. The coefficient ratio of thermal expansion indicates how much a material expands per 1℃ (2.2℉) rise in temperature. Fine Ceramics (also known as "advanced ceramics") have low coefficients of thermal expansion — less than half those of stainless steels.
