Refractory Ceramics Definition

Material that can withstand very high temperatures 3000 c or more without degrading or softening.

Refractory ceramics definition. Showing or characterized by obstinate resistance to authority or control. Whether vitrified or not it is nonporous does not soak up liquids. Members are involved in materials development formulation production and engineering of refractories for the iron steel aluminum and other. A refractory material or refractory is a material that is resistant to decomposition by heat pressure or chemical attack and retains strength and form at high temperatures.

Showing or characterized by obstinate resistance to authority or control. Refractory any material that has an unusually high melting point and that maintains its structural properties at very high temperatures composed principally of ceramics refractories are employed in great quantities in the metallurgical glassmaking and ceramics industries where they are formed into a variety of shapes to line the interiors of furnaces kilns and other devices that process. Such refractory materials as silicon dioxide and aluminum oxide are so severely attacked that their use is hazardous some compounds of hafnium are also used as refractory substances to line the inside of high temperature ovens also under investigation as possible container materials are certain types of refractory ceramics. Stoneware is a rather broad term for pottery or other ceramics fired at a relatively high temperature.

One of a number of ceramic materials for use in high temperature structures or equipment. Refractory synonyms refractory pronunciation refractory translation english dictionary definition of refractory. Historically across the world it has been developed after. The refractory ceramics division of the american ceramic society examines the science production and application of ceramics for use at elevated temperatures and in other hostile environments.

Refractory materials include certain ceramics and superalloys and are used in heat insulation of furnaces jet and rocket engines and parts of space vehicles such as the shuttle. Silicon aluminium magnesium calcium and zirconium. Refractories are inorganic nonmetallic porous and heterogeneous. The term high temperatures is somewhat indefinite but usually means above about 1830 f 1000 c or temperatures at which because of melting or oxidation the common metals cannot be used.

It may or may not be glazed. They are typically composed of oxides of the following materials.
