Metals and Non-metals: Material Properties, Concepts

The physical properties of non – metals are : The solid non-metals are brittle or dull and soft as they can be broken down into a powdery substance or mass on tapping down with the hammer. Few examples are Coal and Sulphur. However, Diamond is an exception as it is the hardest non-metal. Non – metals may be either solids, liquids, or gases.

Ceramic - Wikipedia

Ceramic material is an inorganic, non-metallic, often crystalline oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics.Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
