Yttralox is a transparent ceramic consisting of yttria (Y 2 O 3) containing approximately 10% thorium dioxide (ThO 2). [1] [2] It was one of the first transparent ceramics produced, [3] and was invented in 1966 by Richard C. Anderson at the General Electric Research Laboratory while sintering mixtures of rare earth minerals.
Transparent alumina is currently one of the most mature transparent ceramics from a production and application perspective, and is available from several manufacturers. But the cost is high due to the processing temperature involved, as well as machining costs to cut parts out of single crystal boules.
Between 1879 and 1882, as Art Superintendent at the Linthorpe Art Pottery in Linthorpe in Middlesbrough he designed over 1,000 pots. If his ceramic work from the 1860s onwards (for firms such as Mintons , Wedgwood , Royal Worcester , Watcombe , Linthorpe, Old Hall at Hanley and Ault ) is considered, he must be amongst the most influential ...
Ceramic art is art made from ceramic materials, including clay. It may take varied forms, including artistic pottery , including tableware , tiles , figurines and other sculpture . As one of the plastic arts , ceramic art is a visual art .
Aluminium oxynitride is the hardest polycrystalline transparent ceramic available commercially. [ 2 ] [ needs update ] Because of its relatively low weight, distinctive optical and mechanical properties, and resistance to oxidation or radiation, it shows promise for applications such as bulletproof , blast-resistant, and optoelectronic windows ...
Ceramic material is an inorganic, metallic oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand the chemical erosion that occurs in other materials subjected to acidic or caustic ...
The definition of pottery, used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". [1] End applications include tableware , decorative ware , sanitary ware , and in technology and industry such as electrical insulators and laboratory ware.
However, earthenware can be made impervious to liquids by coating it with a ceramic glaze, and such a process is used for the great majority of modern domestic earthenware. The main other important types of pottery are porcelain , bone china , and stoneware , all fired at high enough temperatures to vitrify.
