This growth is attributed to the increase in infrastructural developments in developing countries such as China, India, and Brazil and high growth rate witnessed by the non-metallic minerals industry. The growing demand for high-grade refractories from iron & steel industries is also an important factor driving the refractories market. Unshaped refractories: The largest segment of refractories market by form Unshaped refractories was the largest segment of the global refractories market, by form in 2016, followed by shaped refractories. The demand for unshaped refractories is driven due to its effective and substantial usage in cement, glass, and ceramic industries. Its availability in various compositions and morphologies is expected to drive its demand globally. Acidic & Neutral refractories: The largest segment of refractories market, by alkalinity Acidic & neutral refractories was the largest segment, of the global refractories market, by alkalinity in 2016. Acidic refractories are rich in silica and alumina content and are mainly used in the glass and ceramics industry, which is expected to drive the market of acidic & neutral refractories. Acidic & neutral refractories are inexpensive, which further fuels their demands globally. The usage of acidic & neutral and basic refractories majorly depends on the kind of end-use industry it is required in. Iron & steel industry: The largest segment of the refractories market, by end-use industry Iron & steel industry was the largest segment of the global refractories market, by end-use industry in 2016. This large share is attributed to the increasing technological advancements and the need for specialized refractory materials and products. Additionally, increasing infrastructure and construction activities in developing economies, such as India, Brazil, Mexico, Russia, and others are contributing significantly to steel consumption, and consequently leading to an increase in the usage of refractories. The Asia-Pacific region was the largest region for Refractories Market, in terms of value and volume, in 2016. The large market size of Asia-Pacific is due to the shifting of manufacturing facilities by large market players from mature markets such as Europe and North America to Asia-Pacific and Middle East & Africa. The large players prefer investing in these regions because they offer a wide range of market penetration opportunities due to the presence of mineral deposits such as magnesite, silica, and alumina, which are the key raw materials used to manufacture refractories, and the abundant availability of workforce and consumers.

Refractories are non-metallic materials that have property to retain its structure even at high temperatures of above 1000 °F. Refractories are used in linings of furnaces, incinerators and reactors in many of the industries. Refractories find application in vessel lining construction of unshaped products, prefabricated elements and bricks in the industries. The key end-user industries for refractories include iron and steel, non-ferrous metals, non-metallic minerals; and non-metallic materials such as glass. Multiple refractory layers and additional insulation materials are necessary to protect the steel structure in the furnaces from aggressive processing conditions. Iron and steel was the largest end-user industry for refractories accounting for about 75% of total market in 2013. The growth of end-user industries and the increasing demand for high performance furnaces has been driving the global refractories market. However, due to increasing equipment efficiency, the refractory consumption of the end-user companies has been declining. The expansion of iron and steel companies in terms of acquisition of new raw material sites or increasing the number of processing plants are generating new demands for the refractories market. The global glass market is growing at fast pace due to its increasing demand from construction and corporate sectors. Refractories consumption per ton of the processed metal varies across the countries. For instance, Japan consumes about 10 kilograms of refractories per ton of steel, whereas with 23 kg/ton, it is very high in case of China. There are basically two categories of refractories in terms of form type namely bricks and shapes and monolithic. The bricks and shapes was the largest refractories segment in 2013 by form type, however, monolithic segment is expected to grow at a higher rate during 2014-2010. In terms of materials type, refractories can be classified into clay and nanoclay. Clay was the largest and fastest growing segment in the refractories market. The total global production of refractories in 2012 was observed to be 45.7 million tons and it is expected to cross 55 milion by 2020. The refractories industry in the recent few years have been observed engaged in some serious research and development which is also being in the development of new generation of refractories termed as Eco Refractories. These types of refractories will be used in furnances for alternative energy production including solar, wind, tidal, geothermal, hydrogen, nuclear and biomass. Asia Pacific was the largest market for refractories market in 2013 followed by Europe. China was the largest producer and consumer of refractories in Asia Pacific in 2013. China is also the one of the largest supplier of refractories raw materials such as refractory bauxite, magnesia, graphite, brown fused alumina and silicon carbide. The high rate of infrastructural development and growing consumer goods such as automobiles in the country is increasing the demand for iron and steel leading to the growth of refractories market in the country. The key companies in the refractories market include RHI AG, ANH Refractories Company, Calderys SA, Wugang Refractory Company Limited, Saint Gobain SA, Refratechnik Holding GmbH and Krosaki Harima Corporation.
