What is crucible definition?

A crucible is a container used for holding and heating materials to high temperatures. The term "crucible" comes from the Latin word "crucibulum," which means "a place of fire." Crucibles can be made of various materials such as ceramic, glass, metal, or graphite, depending on the application requirements. They are commonly used in chemistry, metallurgy, and materials science to melt and refine metals and other materials, as well as in laboratory experiments. Crucibles can withstand high temperatures and are designed to resist chemical reactions and contamination. They come in different shapes and sizes, including cylindrical, conical, and spherical, and can be used with a lid to prevent evaporation or contamination during heating.
