Calcium Sulphate Market: Overview

Calcium sulphate (CaSO4), which occurs naturally as anhydrous and hydrated powder, is an odorless, white, crystalline powder with a melting point of 1400°C. Anhydrite is a mineral that contains anhydrous calcium sulphate, whereas fly alabaster or gypsum contains hydrated calcium sulphate. Numerous compounds of calcium sulphate are available, including selenate, satin, streetlight, tribal, and satin. When heated, calcium sulphate loses its water molecules and transforms into gypsum, also referred to as POP in flies. By adding water, POPs like molds, band-aids, and dividers clump together. Additionally, calcium sulphate is utilized as a desiccant in chemical laboratories, a coating in the paper industry, a soil conditioner in agriculture, and a coloring pigment in paintings.

Calcium Sulphate Market: Growth Drivers

Growing pharmaceutical and healthcare sector to drive the market growth

Gypsum, also known as calcium sulphate, is used in the pharmaceutical and healthcare industry as a calcium supplement that is necessary for bone and cell growth as well as a whitening or coloring agent. It provides a natural organic excipient that contains crucial calcium nutrients and, in the anhydrite form, is also utilized as a desiccant. Calcium sulphate reduces the need for synthetic polymers and other non-organic chemicals by producing an affordable binder, filler, coating, disintegrant, or bulking agent for tablets and capsules. Additionally, it is a component of toothpaste, powders, lotions, and other medical supplies.

For instance, according to the staff study report on the "US-China Economic and Security Review Commission," the pharmaceutical and healthcare sector in China is predicted to rise to a size of 16 trillion RMB (US$ 2.3 million) by 2030. Furthermore, overall pharmaceutical production increased from US$322,407.6 million in 2019 to US$340,898.7 million in 2020, according to the European Federation of Pharmaceutical Industries and Associations (EFPIA). As a result, the demand for calcium sulphate as a calcium supplement will rise, and throughout the projection period, it is projected that this will fuel market expansion.

Calcium Sulphate Market: Restraints

An adverse effect of calcium sulphate on human health is expected to hamper market expansion

Gypsum, commonly known as calcium sulphate, is used in many different sectors but also has negative health impacts. Acute calcium sulphate exposure can cause skin and respiratory tract irritation, itchy, red eyes, a sore throat, and a runny nose. Calcium sulphate can irritate mucous membranes, dull senses of taste and smell, and even cause nose bleeding. Additionally, it can lead to pulmonary nodular fibrosis. Constipation and impaired iron and zinc absorption are two side effects of its high ingestion. Additionally, calcium sulphate in supplement form increases the risk of kidney stones, cardiovascular disease, and prostate cancer with high intake. Thus the adverse effect of calcium sulphate on human health is expected to hamper the market growth.

Calcium Sulphate Market: Opportunities

Increasing demand for calcium sulphate from various end-use industries provides an attractive opportunity for the market growth

The increasing demand for calcium sulphate from various end-use industries such as food & beverages, paper & pulp, paint & coatings, and others are expected to provide lucrative opportunities for global calcium sulphate market expansion during the forecast period. Calcium sulphate is a surface-sizing agent for papers in paperboard mills in the pulp and paper industry. Additionally, calcium sulphate serves as a cost-effective supply of calcium in foods such as bread, cereals, fortified flours, yeast meals, canned vegetables, baking powder, juices, jellies, and preservatives. Furthermore, serving as a buffer in the brewing process is calcium sulphate. In paints & coatings, calcium sulphate is also utilized as an extender pigment.

Calcium Sulphate Market: Segmentation

The global calcium sulphate market is segmented based on the form type, grade, function, industry vertical, and region

Based on the form type, the global market is bifurcated into anhydrous and hydrated. The anhydrous segment accounted to hold the largest market share in 2021 and is expected to maintain its dominance during the forecast period. The anhydrous form is a crystalline solid or fine, odorless white powder. It is used in a wide range of processes, including the manufacture of cement and as a filler in paper.

When used as a filler in the pulp and paper manufacturing process, the anhydrous form of calcium sulphate improves the quality of paper and makes it stiffer, brighter, and simpler to draw on, print on, and write on. Additionally, calcium sulphate in the anhydrous or anhydrite form can be utilized as a desiccant in the medical field, such as in dentistry. As a result, the anhydrous form of calcium sulphate is chosen over other forms of calcium sulphate due to all the features it possesses, which is fueling its rapid expansion.

On the basis of Grade, the global calcium sulphate market is bifurcated into Technical Grade, Food & Pharma Grade and Others.

By Function, the global calcium sulphate market is split into Coagulant, Thickening Agent, Excipient, Desiccant, Additive, Intermediate, Colorants, Coating Agent, Drying Agent, Anti-Caking Agent and Others.

Based on industry vertical, the global calcium sulphate market is segmented into food & beverages, cosmetic & personal care, pulp & paper, building & construction, chemical & petrochemical, pharmaceutical & healthcare, agriculture, mining and others. The building & construction segment holds the largest market share during the forecast period. Calcium sulphate is used in the building and construction sector as an ingredient in aerated blocks, as a shrinkage-reducing agent, and as a cement mixture. It serves as the raw ingredient for making drywall, plaster, and other construction-related products.

The building and construction sector is expanding. For instance, according to the U.S. Department of Commerce reports, the number of privately owned housing units authorized by building permits in March 2022 was approximately 1,873,000, which is 6.7% more than March 2021’s approximately 1,755,000 units and is up 0.4% from February 2022’s 1,865,000 units. Thus, driving segmental growth during the forecast period.
