Refractories are inorganic, nonmetallic materials and engineered components used inside furnaces, kilns, reactors, converters, ladles, tundishes, smelters, glass tanks and other high temperature process equipment. They separate the process environment from the structural shell while retaining sufficient strength, dimensional stability and chemical resistance during exposure to molten metal, slag, glass, clinker, hot gas, ash and reactive vapors. Their economic function is determined by the ability to maintain containment, control heat transfer and preserve process geometry for a defined operating campaign. Refractory performance depends on mineral chemistry, phase composition, purity, porosity, grain size distribution, bonding system, density and thermal expansion. Magnesia, doloma, alumina, bauxite, silica, zircon, graphite, silicon carbide and related engineered phases are selected according to temperature, atmosphere and contact chemistry. Basic slags require chemically compatible basic refractories such as magnesia based systems. Molten glass requires materials with low dissolution rates and controlled interaction with the glass phase. Carbon containing materials reduce slag wetting and improve thermal shock resistance in many steelmaking applications. Silicon carbide provides high thermal conductivity, abrasion resistance and chemical stability in selected industrial environments. Refractory consumption originates from progressive material loss during operation. Chemical dissolution, slag and metal penetration, oxidation, thermal shock, structural spalling, abrasion, erosion and mechanical impact reduce the effective lining thickness. Local temperature gradients and repeated heating cycles generate internal stress. Penetrating liquids can alter the original mineral phases and weaken the refractory matrix. A lining is repaired or replaced when residual thickness, wear variability, heat loss, product quality or equipment risk reaches the operator's acceptable limit. Service life therefore depends on operating temperature, process chemistry, throughput, furnace design, maintenance practice, installation quality and refractory formulation. Shaped refractories are manufactured as bricks, blocks and functional components with controlled dimensions before installation. Unshaped refractories are supplied as castables, gunning mixes, ramming materials, mortars and related formulations that form the lining at the customer site. Functional refractory products include nozzles, slide gate components, stopper systems and other flow control parts used where geometry and material behavior directly affect process stability. The relative use of these product forms changes with furnace design, repair practice, campaign targets and customer operating requirements. Refractories are consumed as part of the operating life of high temperature industrial assets. Steelmaking generates frequent replacement demand because several vessels and casting components are exposed during each production sequence. Cement kilns and glass furnaces operate through longer lining campaigns. Nonferrous smelters face severe chemical attack from metal and slag systems. Refractory demand therefore follows downstream output, installed furnace capacity, operating hours, process route, unit refractory consumption, maintenance intensity, campaign life and new furnace construction.
The global refractories market was US$33.97 billion in 2025, with finished refractory production of 34.82 million tonnes and an average price of US$975.75 per tonne. Production declined by 3.73 million tonnes from 2021. Iron and Steel accounted for 2.44 million tonnes of this reduction, Cement and Lime for 0.73 million tonnes and Other Industries for 0.65 million tonnes. Nonferrous Metals and Glass added approximately 0.09 million tonnes during the same period. The physical contraction was therefore generated principally inside the large, mature steel and cement furnace base. Average price increased from US$859.89 per tonne in 2021 to US$1,030.96 in 2023 and declined to US$975.75 in 2025. Magnesia, alumina, bauxite, graphite, zircon containing materials, silicon carbide, metallic additives and binders account for a substantial portion of refractory manufacturing cost. Electric melting, high temperature firing, drying and tempering add electricity and fuel exposure. The 2022 and 2023 increase in raw material, energy and conversion costs moved through refractory selling prices. Lower input costs and weaker furnace demand reduced part of that increase during 2024 and 2025.
Iron and Steel consumed 24.20 million tonnes of refractories in 2025, equal to 69.50% of global refractory volume. Refractory consumption occurs repeatedly through the steelmaking sequence. Blast furnaces, basic oxygen furnaces, electric arc furnaces, ladles, RH vessels, tundishes and continuous casting systems expose their working linings to molten metal, slag penetration, chemical dissolution, oxidation, thermal cycling and mechanical erosion. Steel output determines the number of heats processed. Furnace route determines which refractory systems receive those heats. Campaign life determines how frequently a lining is replaced. Gunning, fettling, slag repair and local monolithic maintenance extend campaign life and reduce the quantity of new brick required for each tonne of steel. Higher performance magnesia carbon linings, improved installation control and better furnace operating practice have reduced specific refractory consumption over time. The audited steel refractory volume declines from 26.64 million tonnes in 2021 to 24.20 million tonnes in 2025 even with continuing steel capacity additions in selected emerging markets.
China remains the largest physical variable inside steel refractory demand. Its refractory consumption falls from 19.72 million tonnes in 2025 to 18.42 million tonnes in 2032 across all applications. Mature steel capacity, lower utilization in parts of the furnace fleet, improvements in lining life and declining refractory consumption per tonne reduce replacement tonnage. India moves from 1.78 million tonnes to 2.73 million tonnes during the same period. Indonesia increases from 0.56 million tonnes to 0.85 million tonnes and Vietnam from 0.33 million tonnes to 0.47 million tonnes. New steel capacity in these countries requires an initial furnace lining at commissioning and creates a recurring replacement base after operation begins. China, Japan and South Korea contain substantially larger installed furnace fleets, so reductions in their production and specific refractory consumption absorb a large portion of the tonnage created by new Asian capacity.
Changes in steelmaking route also change refractory consumption without producing a one for one change in crude steel output. Electric arc furnaces eliminate several refractory consuming stages associated with an integrated blast furnace route. The EAF itself requires magnesia carbon working linings, gunning mixes, hearth materials and taphole products. DRI charged electric furnaces can impose higher refractory wear in selected zones because slag practice, iron oxide content, temperature and furnace operating conditions differ from scrap melting. Secondary metallurgy and continuous casting create another refractory demand layer through ladles, purging systems, slide gates, stopper rods, submerged entry nozzles and tundish systems. These products carry much higher value per tonne than bulk furnace linings because dimensional control, thermal shock resistance, erosion resistance and casting reliability affect steel cleanliness and continuous casting stability. The steel refractory market therefore remains close to 24 million tonnes through 2032 even as its internal product mix changes.
