Refractory material practitioners often encounter some professional terms in their daily work. Some terms are too unpopular and may confuse colleagues who are new to this industry.This will facilitate the daily work needs of refractory material practitioners. The following is the first article of 142 Professional Terms for Refractory Materials

001. Abrasion

Loss of material surface due to mechanical action of moving solids.

002. Acid refractory acid refractory

Usually refers to refractory materials with silica as the main component (108). It is easy to react chemically with alkaline refractory materials (009), alkaline slag (122), high-aluminum refractory materials (072) or alkali-containing compounds at high temperatures.

003. Aggregate/grain

The particle part in the refractory (108) component usually refers to coarse particles.

004. Air setting jointing material / air setting mortar / refractory cement

A joint material (077) that hardens through chemical bonding (036) or hydration bonding (074) at room temperature.

005. Alkali resistance

The ability of refractory materials (108) to resist chemical damage in alkaline environments.

006. Aluminum-silicate

Raw materials with alumina and silica as the main components.

007. Anti-oxidant

Metal or other substances added to improve the oxidation resistance of carbon-containing refractory materials (108).

008. Apparent porosity

The ratio of the volume of the open pores (093) in the refractory material (108) to its total volume (018).

009. Basic refractory

Refractory materials (108) that easily react chemically with acidic refractory materials (002), acidic slag (122), acidic flux or alumina at high temperatures.

010. Binder

Substances added to non-plastic pellets or fibrous materials to impart workability (141) and green strength (067) or dry strength (055).

011. Bloating

Refers to the permanent expansion of some clay or refractory materials (108) that occurs after heating. NOTE: Bloating is usually the result of pore formation.

012. Big brick block

Usually refers to refractory products larger than bricks (014).

013. Bond

The behavior of causing bonding between the constituent particles of the refractory material (108) and providing strength.

014. Brick

A refractory product with a certain shape, usually a rectangular parallelepiped, that can be picked up with one hand.

015. Bulk ceramic fiber / bulk refractory ceramic fiber

Refractory ceramic fibers (026) in loose form before being used to prepare articles.

016. Bulk density

The ratio of the dry mass of refractory material (108) to its total volume (018).

017. Bulk density (of a granular material) /grain bulk density

The ratio of the dry mass of granular material to the total volume (018).

018. bulk volume

The sum of the volumes of solids, open pores (093) and closed pores (039) in the refractory material (108).

019. Calcination

A heat treatment of refractory raw materials that produces physical or chemical changes that eliminate volatile chemically bound components and volume changes.

020. Carbon monoxide destruction carbon monoxide disintegration

The decomposition of carbon monoxide results in the deposition of char, leading to damage to the refractory material (108).

021. carbon monoxide resistance carbon monoxide resistance

The ability of refractory materials (108) to resist carbon monoxide damage (020) at a certain temperature and carbon monoxide atmosphere.

022. Carbonization

A process that removes volatile components from refractory materials (108) that are combined or impregnated with asphalt, tar, resin, etc. and retains carbon residue.

023. Castable ceramic fiber/castable refractory ceramic fiber

Castable containing inorganic and/or organic binders (010) and using refractory ceramic fiber (026) as the main raw material.

024 casting

Construction method of pouring or pumping unshaped refractory materials (138) with sufficient fluidity. Note: If necessary, vibration and pounding can be used to shape and densify it.

025. ceramic bond ceramic bond

Bonding (013) due to sintering (121) or liquid phase formation at a certain temperature.

026. Refractory ceramic fiber ceramic fiber/refractory ceramic fiber

Refers to artificial mineral fibers suitable for use as heat insulation materials above 800°C.

027. Refractory ceramic fiber blanket ceramic fiber blanket/refractory ceramic fiber blanket

It is usually a needle-punched, soft refractory ceramic fiber (026) product that does not contain binder (010) and has a certain size.

028. Refractory ceramic fiber board ceramic fiber board/refractory ceramic fiber board

Usually refers to hard flat-shaped refractory ceramic fiber (026) products containing inorganic or organic binders (010) and produced by wet methods.

029. Refractory ceramic fiber felt ceramic fiber felt/refractory ceramic fiber felt

It contains a certain amount of inorganic and/or organic binders (010) and has a certain size and soft sheet-like refractory ceramic fiber (026) products.

030. Refractory ceramic fiber mat ceramic fiber mat/refractory ceramic fiber mat

Soft, non-needle punched refractory ceramic fiber (026) products.
