Do Ceramic Materials Have A Hard Trait

Ceramics may be crystalline or non crystalline and are strong stiff brittle chemically inert and do not conduct heat or electricity but properties vary widely.

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. Ceramics generally can withstand very high temperatures ranging from 1 000 c to 1 600 c 1 800 f to 3 000 f. Ceramic materials are brittle hard strong in compression and weak in shearing and tension. 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.

Ceramics are strong in compression and weak in shearing and tension which make them challenging to saw grind lap and polish. Also they are generally hard and brittle with very good chemical and thermal stability. Ceramic powder consists of ceramic particles and additives that improve a powder s ease of use during component fabrication. They typically possess high melting points low electrical and thermal conductivity values and high compressive strengths.

Ceramic materials are special because of their properties.
