Calcium bromide is the name for compounds with the chemical formula CaBr2(H2O)x. Individual compounds include the anhydrous material (x = 0), the hexahydrate (x = 6), and the rare dihydrate (x = 2). All are white powders that dissolve in water, and from these solutions crystallizes the hexahydrate.
VIMATERIAL provides various types of bromides, please contact us if you need them.

Direct reaction method: react calcium carbonate (CaCO₃) or calcium hydroxide (Ca(OH)₂) with hydrogen bromide (HBr) to generate calcium bromide.
Bromination reaction method: prepare calcium bromide by direct reaction of metallic calcium (Ca) with bromine (Br₂)
Double decomposition method: prepare by reaction of soluble calcium salt (such as calcium chloride) with sodium bromide
Calcium bromide is a dehydrating agent used in photography, food preservatives, wood preservatives, fire retardants and freezing mixtures.
It is used as an oxidizer for mercury emissions control.
It is widely used for the preparation of drilling fluids, completion fluids and drilling muds formulations.
It also finds application in the manufacture of mineral water.
Our products implement the most stringent quality management system. There are strict inspection standards for incoming materials, processes, final inspections, and factory inspections. Strict isolation measures will be adopted for unqualified processing to prevent unqualified products from flowing into the next process. Samples will be provided to customers according to customer requirements for re-inspection.
Inner vacuum packaging, outer carton packaging.
Sealed storage: Calcium bromide is highly hygroscopic and should be stored in a sealed moisture-proof container.
Environmental requirements: Store in a dry, ventilated environment, avoid high temperature and strong light.
Keep away from corrosive substances: Avoid contact with acids and oxidants to prevent chemical reactions.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
