Properties Of Clay Ceramics

Now we are going to see about the properties of clay.

Properties of clay ceramics.

Great hardness and strength. If we re summarizing their properties we can say that ceramics have. Low electrical and thermal conductivity they re good insulators. Coarse and fine ceramic products have generally different properties and surface finishes.

High melting points so they re heat resistant. 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. Cordierite is a crystalline magnesium aluminosilicate. Clay differs from inelastic earth and fine sand because of its ability when wetted with the proper amount of water to form a cohesive mass and to retain its shape when molded.

Coating of a powdered ceramic material suspended in water which melt smooth and bond to the clay surface in a glaze firing. It combines with one or more minerals with the traces of silica organic impurities and metal oxides. A further classifying step is differentiation on the basis of porosity which reflects the decisive influence of pores on material properties. Considerable durability they re long lasting and hard wearing.

Clays are generally termed as hydro aluminosilicate. Glazes that are matured in a glaze firing are like a glass coating on the ceramic. Properties of some common ceramics. These are all the basic properties of ceramic material.

This quality is known as clay s plasticity. A criterion that readily distinguishes between porous and dense materials is water absorption. Clay has three various compositions.
