refractory, any substance which includes an unusually superior melting place Which maintains its structural Homes at really large temperatures. Composed principally of ceramics, refractories are employed in fantastic quantities during the metallurgical, glassmaking, and ceramics industries, the place they are fashioned into several different styles to line the interiors of furnaces, kilns, and also other units that procedure supplies at high temperatures.

but that spelling, while much more In step with its Latin parent, had fallen outside of use from the century's conclude. Refractarius,

Mullite refractories are solidified by sintering in electric powered furnaces at high temperatures. They may be by far the most steady of your aluminosilicate refractories and have excellent resistance to significant-temperature loading. Mullite bricks are Employed in blast-furnace stoves and in the forehearth roofs of glass-melting furnaces.

These examples are programmatically compiled from several online sources For example present-day use in the phrase 'refractory.' Any thoughts expressed inside the examples usually do not symbolize All those of Merriam-Webster or its editors. Send out us responses about these illustrations.

The ramming content refers to some bulk material formed by a strong ramming process, which happens to be made up of a specific dimensions of refractory material, a binder, and an additive.

that means “high-melting.”) The assets of chemical inertness is of Specific significance in metallurgy and glassmaking, where by the furnaces are subjected to incredibly corrosive molten components and gases. In addition to temperature and corrosion resistance, refractories ought to possess superior Actual physical have on or abrasion resistance, and In addition they has to be resistant to thermal shock. Thermal shock takes place when an object is quickly cooled from high temperature. The surface layers deal in opposition to the inner levels, leading to the event of tensile anxiety and the propagation of cracks. Ceramics, Despite their nicely-recognised brittleness, might be manufactured resistant to thermal shock by changing their microstructure in the course of processing. The microstructure of ceramic refractories is fairly coarse when compared with whitewares for instance porcelain or Despite fewer finely textured structural clay merchandise such as brick.

b : unresponsive to stimulus c : immune, insusceptible immediately after recovery they had been refractory to an infection

gamers will likely be ejected from the sport believing that procedures are only for Other individuals, he's been refractory

Special refractory is really a sort of refractory substance with special Qualities manufactured from a number of superior melting point oxides, refractory non-oxides, and carbon.

time period in nonhuman primates and people stays controversial. Through the Cambridge English Corpus Genetic mapping and positional cloning on the t haplotype lethals has actually been hindered because of the inversions that render t haplotypes refractory

The casting substance is usually Utilized in a variety of industrial furnaces. It is the most widely employed monolithic refractory materials.

Because of the superior strengths exhibited by their Principal chemical bonds, numerous ceramics have unusually fantastic mixtures of substantial melting level and chemical inertness. This can make them beneficial as refractories. (The word refractory emanates from the French réfractaire,

The inspiration of Electrical power-intensive industries to decarbonize has become significantly essential, particularly from the context of the eu Green Offer. This ambitious plan framework, initiated by the eu Union in 2020, aims to transform the area into the planet's to start with climate-neutral continent by 2050. Electricity-intensive industries, which include Iron and Metal, Cement, Glass and Super alloys, are pivotal contributors to carbon emissions. The urgent will need to address local climate modify, the targets outlined in the European Inexperienced Deal, financial incentives, plus a growing world wide consciousness of environmental sustainability, have led Power-intense organizations to decide to turning out to be Net Zero by 2050.

The lining of each reactor, transportation vessel or kiln takes advantage of a wide range of refractory goods which Api 936 includes bricks, monolithics and substantial-temperature insulation wool.
