They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Ceramics generally can withstand very high temperatures, ranging from 1,000 °C to 1,600 °C (1,800 °F to 3,000 °F).
What makes ceramic so strong?
The two most common chemical bonds for ceramic materials are covalent and ionic. The bonding of atoms together is much stronger in covalent and ionic bonding than in metallic. This is why ceramics generally have the following properties: high hardness, high compressive strength, and chemical inertness.
Are ceramics strong in tension?
Ceramics have compressive strengths about ten times higher than their tensile strength. The tensile strength of ceramics and glasses is low because the existing flaws (internal or surface cracks) act as stress concentrators.
