Raw Materials And Ores Of Traditional Ceramics In Nature

Ceramics are very abuındant at earth crust. Because of that, ceramics are reachable materials in most engineering and daily applications. For traditional basic ceramics, there are bunch of ores and raw materials in nature. In this article, we will explain these ores and raw materials of basic traditional ceramics below.

Bauxite to produce alumina.

What Are The Ores And Raw Materials Of Ceramics?

Generally, silicates, quartz and other kinds of clays are the most common raw material for traditional ceramics. But clays are the most used raw material in  nature to obtain traditional ceramics. Clays are the hyrous aluminum silicate, that mixed with water to be shaped plastically to desired shapes. Kaolinite(Al2Si2O5(OH)4) is the most common source of clay.

After shaping of clay in plastic from that is mixed with water, a process called as ‘firing’ is applied to obtain hard and brittle structure from clay. Firing temperature must be suitable for clay that is processed.

Silica(SiO2) is also principal raw material for traditional ceramics. One of the most known product of Silica is glass. Silica is avaliable in nature in the form of quartz. And quartz can be found from sandstone. Because of abundancy of sandstone in nature, and the easiness of the process of sandstone to obtain Silica, silica is very cheap material.

Feldspar is also very important raw material for traditional ceramics. The structure of Feldspar is, aluminum silicate combined with calcium, barium, sodium and potassium.

As you remember from the production of aluminum from its ore, alumina is processed from a mineral called bauxite. This bauxite metarial is the principal ore of aluminum production. Alumina also a product of bauxite, which is an also very important raw material for traditional ceramics. Alumina ceramic is used as an abrasive in grinding wheels and as a refractory brick in furnaces.
