Applications and Processing of Ceramics Flashcards
A process wherein most inorganic glasses can be made to transform from a noncrystalline state to one that is crystalline by the proper high-temperature heat treatment.
crystallization
are a familiar group of ceramics; containers,
lenses, and fiberglass represent typical applications.
Glasses
One of the most widely used ceramic raw materials
Clay Products
compounds of metallic and non metallic elements
Ceramics
The word ‘ceramic’ is originated from greekword keromikos, which means
burnt stuff
a vital ceramic category, excel in enduring high temperatures and harsh environments without melting or reacting
Refractory ceramics
comprising high-purity fireclays, alumina, and silica mixtures, are vital for furnace construction and insulation
Fireclay Refractories
mainly composed of silica, excel in withstanding high temperatures and are commonly used in steel- and glass-making furnaces
Silica Refractories
They’re especially effective against slags rich in MgO and CaO, making them popular in various steel-making processes.
Basic Refractories
such as high-purity oxides like alumina, silica, magnesia, beryllia (BeO), zirconia (ZrO2), and carbide compounds like silicon carbide (SiC), serve specific applications. These materials are often expensive.
Special Refractories
essential for wearing, grinding, or cutting softer materials.
Abrasive ceramics
produced by grinding and mixing clay and lime-bearing minerals, then heating the mixture
Portland cement
widely used for their ability to form a paste when mixed with water, setting into solid structures of various shapes.
Inorganic cements
because of their unique
mechanical, chemical, electrical, magnetic, and optical properties and property combinations, these type of ceramics were used by modern technologies.
Advanced ceramics
generate electric fields when
mechanical strains (i.e., dimensional changes) are imposed.
Piezoelectric ceramics
