Calcium Aluminate Market: Overview

Calcium aluminates are a series of minerals produced by collectively heating aluminum oxide and calcium oxide at high temperatures. These exhibit outstanding characteristics such as resistance to heat, abrasion, and corrosion. Calcium aluminates are often used in the advancement of materials and formulation technologies.

Calcium aluminates are easily available in large volumes. These compounds contain metallic oxide and negatively-charged alumina ion. They are used in various end-use applications such as ceramics manufacturing, water treatment, and cement formulations.

Calcium aluminates are available in different phases such as monocalcium aluminate (known as CA with chemical formula CaO·Al2O3), tricalcium aluminate (known as C3A with chemical formula 3CaO·Al2O3), and dodecacalcium hepta-aluminate (known as C12A7 with chemical formula 12CaO·7Al2O3).

Calcium aluminate is commonly employed in the manufacture of cements (also known as aluminous cement) and refractories. Other uses of calcium aluminate comprise metallurgy, desulfurization of ladle furnace, mineral reagents, and high-performance binders.

Calcium Aluminate Market: Drivers & Restraints

Calcium aluminate cements that are used in the construction industry are made up of lime-alumina compounds as their primary reactive phase. Calcium aluminate cements are alternatively known as high alumina cements (HACs) or aluminous cements. Requirement of sulfate resistant cements has led to the development of these cements. Calcium aluminate cements are primarily used as binders in monolithic refractories. Other applications include chemical resistant concretes and mortars, protective coatings, sewer applications, industrial flooring products, tile adhesives, and expansive grouts. Calcium aluminate cements are also employed in building chemistry products and mining.

Calcium aluminates are used in reducing ladle slag in steel refining. The usage of calcium aluminates have increased due to the requirement of fluorspar-free ladle slag fluxing, and their use being a very cost effective approach. The usage of fluorspar is limited to aluminum-killed steel workshops. As result, the usage of calcium aluminate as increased as substitute for fluorspar for effective and rapid fluidization of calcium oxide (CaO). The usage of calcium aluminate enables dilution of manganese oxide (MnO) and iron oxide (FeO) levels in the carryover slag and offers fluidity and basicity essential for efficient steel refining in the ladle.

Calcium Aluminate Market: Key Segments

Calcium aluminates are also used for desulfurization in the ladle furnace, which is a major metallurgy application. The usage of calcium aluminates enables quick generation of highly reactive slag, which is then saturated with lime, resulting in ideal desulfurization.

Calcium aluminate is also used as high-performance binder in mortars and concretes that are employed in specific applications where resistance to heat, abrasion, and corrosion is required in combination with rapid setting. Based on these parameters, different grades of calcium aluminates are available in the calcium aluminate market. Hydraulic binders of calcium aluminates are produced when calcium aluminates are combined with other required components. As a result, calcium aluminates can be employed as complex hydraulic binders and mineral reagents.

Calcium aluminate is also used as reagent in non-hydraulic systems in foundries and metallurgical treatments in steel and iron industries. These applications consume particular grades of calcium aluminate for entrapment of molten metal impurities, owing to its low-temperature melting properties.

Calcium Aluminate Market: Regional Outlook

Based on geography, the global calcium aluminate market for can be classified into North America, Latin America, Europe, Asia Pacific, and Middle East & Africa. In terms of demand, Asia Pacific is the leading region of the global calcium aluminate market, followed by Europe and North America, respectively. Countries such as China, India, South Korea, Japan, Indonesia, and Vietnam are projected to contribute significantly to the calcium aluminate market in Asia Pacific in the near future. Asia Pacific is also projected to continue its dominance in the global calcium aluminate market during the forecast period. China is expected to be the leading consumer of calcium aluminate in the region in the near future.

North America is one of the high potential regions of the global calcium aluminate market; the U.S. dominates the calcium aluminate market in the region in terms of demand. Demand for calcium aluminate market in Western Europe is likely to be higher than that in Rest of Europe in the next few years.
