Difference Between Metals And Ceramic Crystals

I hope this answers your question.

Difference between metals and ceramic crystals.

We have discovered more than 4000 minerals and they have a crystalline structure inside the earth due to heat and various other reactions minerals and rocks melt together. Ceramic crystal structures broader range of chemical composition than metals with more complicated structures usually compounds between metallic ions e g. The crystals in the solidified metal are called grains and the surfaces between them are named grain boundaries. O n cl called anions bonding will usually have some covalent character but is usually mostly ionic.

Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. Fe ni al called cations and non metallic ions e g. Differences between pure and soft metals and ceramics are very large but metalic materials and steel used for industrial machine and equipments hardened to give designed strength. Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics.

Mineralogy is the study of minerals. Increase of strength reduce the ductility down to show brittle fracture depending on the test condition and its strength.
