Sapphire is a single crystal form of alumina.

Fine ceramics definition. Porcelain vitrified pottery with a white fine grained body that is usually translucent as distinguished from earthenware which is porous opaque and coarser the distinction between porcelain and stoneware the other class of vitrified pottery material is less clear in china porcelain is defined as pottery that is resonant when struck. Common examples are earthenware porcelain and brick. Ceramics synonyms ceramics pronunciation ceramics translation english dictionary definition of ceramics. Of or relating to such a product.

Most ceramic materials such as alumina and its compounds are formed from fine powders yielding a fine grained polycrystalline microstructure that is filled with scattering centers comparable to the wavelength of visible light. Fine ceramics are carefully engineered materials in which the chemical composition has been precisely adjusted using refined or synthesized raw powder with a well controlled method of forming and sintering. Fine ceramics raw material alumina al o alumina is the most widely used fine ceramic today globally and epitomizes fine ceramics. Earthenware definition pottery of baked or hardened clay especially any of the coarse opaque varieties.

A ceramic is any of the various hard brittle heat resistant and corrosion resistant materials made by shaping and then firing a nonmetallic mineral such as clay at a high temperature. How to use porcelain in a sentence. Any of various hard brittle heat resistant and corrosion resistant materials made by shaping and then firing a nonmetallic mineral such as clay at. It offers superior mechanical strength electrical insulation high frequency retention thermal conductivity heat resistance and corrosion resistance.

Testing of methods and products of building ceramics fine ceramics and industrial ceramics patents wipo the ceramic material is a porous no fines ceramic material preferably a composite ceramic material 1 2 3 with two three or more layers designed as a hollow sphere. In the west it is a material that is translucent. The crystallinity of ceramic materials ranges from highly oriented to semi crystalline vitrified and often completely amorphous e g glasses. Thus they are generally opaque as opposed to transparent materials.
