Resistant to heat, capable of standing high temperatures in the range of 1300 ºC plus.
1) Heat-resistant material, usually non-metallic, used for furnace linings etc., 2) the quality of resisting heat.
Any material that withstands the high heat needed for melting glass, the two most common being clay and ceramic fiber substances. Special clays fire up to form bricks that do not deform in the heat. If previously fired clay (grog) and organic material is added to the mix, insulating firebrick is created by the empty spaces in the fired clay. Ceramic fiber is a result of space research and insulates. Two other refractories, known to gardeners, and sometimes used as insulation are vermiculite, which is expanded mica from volcanic regions and perlite, which is made in some way.
The property of being able to exist in solid form under conditions of very high temperature. Refractory elements are characterized by a high temperature of vaporization; they are the first to condense into solid form when a gas cools, as in the solar nebula.
A nerve or muscle that resists stimulation, or a condition that resists treatment.
A ceramic material than can resist great heat and is therefore suitable for lining furnaces. Fireclay, dolomite, magnesite and silica are examples.
Brick material placed inside the firebox to collect and radiate heat from inside a fireplace.
materials with high melting/boiling temperatures.
A material, usually ceramic, that resists the action of heat, does not fuse at high temperatures, and is very difficult to break down.
lining consisting of material with a high melting point; used to line the inside walls of a furnace
resistant to authority or control; "as refractory as a mule"
marked by stubborn resistance to and defiant of authority or guidance; "a recalcitrant teenager"; "everything revolves around a refractory individual genius"
stubbornly resistant to authority or control; "a fractious animal that would not submit to the harness"; "a refractory child"
a chemical which raises the melting temperature
a chemical with a high melting point
a material that will retain its shape and chemical identity when subjected to high temperatures and is used in applications that require extreme resistance to heat, such as furnace linings
a material which stubbornly resists softening, fusion, the action of fluxes and slags, and other effects, physical and chemical, of high temperatures
Material that can be exposed to high temperature without deterioration.
Mineralized material in which gold is not amenable to recovery by conventional cyanide methods due to either encapsulation by other minerals or the presence of elemental carbon.
describes the ability to withstand high temperatures without damage. It is also used to describe bricks with refractory properties.
A high temperature material.
Hard, heat resistant substances such as fire clay, bricks or blocks. The refractory protects a furnace shell from abrasion, heat and oxidation.
Inorganic, non-metallic, ceramic materials which retain their physical shape and chemical identity in the presence of extremely high temperatures.
A material's ability to endure heat without deforming.
(1) A material of very high melting point with properties that make it suitable for such uses as furnace linings and kiln construction. (2) The quality of resisting heat.
a metal or ceramic that may be exposed to extremely high temperatures without deteriorating rapidly or without melting.
Masonry of various chemical properties used to reflect heat.
the more robust materials (e.g. silicate, metal, graphite) which make up dust grain cores. Compare with volatile.
A material having the ability to retain its physical shape and chemical identity when subjected to high temperatures.
Any material that will not bend, warp, deform or explode at a specific high temperature.
Material that is design to withstand heat and high temperatures. The Refractory Material that Forno Bravo uses for its Pizza Ovens and Refractory Fireplaces is a high-tech composite of tempered alumina and woven ceramic silica. For more, read our Refractory Primer.
In timber drying this term is used to indicate high resistance to moisture loss during drying.
A metal or ceramic having a high melting temperature, usually over 1700 C. Example refractory metals are tungsten, molybdenum, rhenium, and zirconium, while example refractory ceramics are alumina, zirconia, yttria, and chromia.
A dense ceramic material commonly used for high temperature applications.
Heat-resistant ceramic material.
refers to prostate cancer resistant to hormone therapy.
Stubborn, obstinate, hard to manage (used in reference to slaves)
resistant to heat, hard to melt.
Capable of withstanding very high temperatures. The kiln furniture has to be able to remain stable at temperatures in excess of the normal firing temperature an must be made of refractory materials.
A high melting point material, various refractories exist in the industry with many applications including the direct containment of molten aluminium.
Heat-resistant material, usually non-metallic, used for furnace linings etc. The quality of resisting heat. Material usually made of ceramics, which is resistant to high temperatures, molten metal, and slag attack.
Resistant to melting or fusion; a ware or material that does not fuse under 2500 degrees Fahrenheit; a substance that raises the melting point of another material. Refractory materials are the basis of high temperature ceramics.
A heat-insulating material, such as firebrick or plastic fire clay, used for purposes as lining combustion chambers.
A material with a high melting point, which makes it useful as a barrier between the heat source and a material that you don't want to melt, like the sides of an oven, etc..
A substance, usually clay, capable of resisting high temperatures.
Refractory is the quality of a material to retain its strength at high temperatures. Refractory materials are used to make crucibles and linings for furnaces, kilns and incinerators. There is no clearly established boundary between refractory and non-refractory materials, though a practical requirement often cited is the ability of the material to withstand temperatures above 1100 °C without softening.
