Do Ceramic Materials Have A Hard Trait

Ceramic materials are special because of their properties.

Do ceramic materials have a hard trait.

The ionic and covalent bonds of ceramics are responsible for many unique properties of these materials such as high hardness high melting points low thermal expansion and good chemical resistance but also for some undesirable characteristics foremost being brittleness which leads to fractures unless the material is toughened by reinforcing agents or by other means. Michael pfeifer in materials enabled designs 2009. Ceramics generally can withstand very high temperatures ranging from 1 000 c to 1 600 c 1 800 f to 3 000 f. Ceramic powder consists of ceramic particles and additives that improve a powder s ease of use during component fabrication.

Ceramics are strong in compression and weak in shearing and tension which make them challenging to saw grind lap and polish. Porcelain has been described as being completely vitrified hard impermeable even before glazing white or artificially coloured translucent except when of considerable thickness and resonant. They typically possess high melting points low electrical and thermal conductivity values and high compressive strengths. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
