Calcium magnesium acetate — CaMg₂(CH₃COO)₆

⚡Quick Reply

Overview

XRD Chemical is a professional Calcium Magnesium Acetate (CMA) manufacturer and supplier in China, offering high-purity CMA as an environmentally friendly alternative to traditional chloride-based deicers and ice melts.

Calcium magnesium acetate is a mixed metal acetate salt with the formula Mg₂Ca(OAc)₆, where OAc represents the acetate anion. It appears as white to off-white granules or powder. With a true density of approximately 1.454 g/cm³, CMA is notably less dense than chloride salts, a characteristic explained by an unusually large unoccupied void space of about 9.4% within its crystal structure.

CMA is valued primarily for its non-corrosive, non-toxic, and biodegradable properties. It is commonly used as a deicing agent for bridges, roadways, airport runways, parking garages, and other infrastructure where corrosion protection is critical. Unlike chloride salts, CMA has no known adverse effects on concrete, steel, aluminum, vegetation, or soil chemistry. It is also utilized as an industrial adsorbent for removing hydrogen sulfide and other acid gases from gas streams.

Why Choose XRD Calcium Magnesium Acetate:

• Non-corrosive and non-toxic — safe for bridges, vehicles, and aluminum surfaces
• Biodegradable with no known adverse effects on plants, soil, or groundwater
• Effective de-icing down to -27°C eutectic temperature
• Also suitable for H₂S removal in gas treatment and industrial adsorption
• White granular or powder form, 99% purity available
• Custom packaging and global delivery supported
• Free samples available for evaluation
• COA and MSDS documents available for download

FAQ

Q What is Calcium Magnesium Acetate (CMA)?

Calcium Magnesium Acetate (CMA) is a mixed metal acetate compound with the formula Mg₂Ca(OAc)₆. It is a white granular or powder material used primarily as an environmentally friendly road deicer and as an adsorbent for removing acid gases such as hydrogen sulfide from industrial gas streams.

Q How does CMA compare to traditional rock salt and chloride deicers?

CMA is non-corrosive and biodegradable, unlike sodium chloride, calcium chloride, and magnesium chloride which can damage concrete, corrode steel, and harm roadside vegetation. CMA has a eutectic temperature of -27°C, about twenty degrees lower than rock salt. Its primary drawback is cost — CMA is roughly twenty times more expensive than rock salt — so it is typically reserved for sensitive structures like bridges, airport runways, and parking garages.

Q Does CMA damage concrete or steel?

No. CMA has no known deleterious effects on concrete or steel. It does not stain aluminum surfaces and shows no significant corrosion of steel, aluminum, or zinc. This makes it the preferred choice for bridges, reinforced concrete structures, and other corrosion-sensitive infrastructure.

Q Is CMA safe for the environment, pets, and humans?

Yes. CMA is considered practically non-toxic by ingestion, inhalation, and skin absorption. It has no known adverse effects on plants, does not degrade soil structure, and its poor mobility in soil reduces groundwater contamination risk. It is widely considered a pet-friendly and environmentally safe alternative to chloride-based deicers.

Q What are the industrial applications of CMA beyond deicing?

Beyond deicing, CMA is used as an industrial adsorbent for removing hydrogen sulfide (H₂S) and other odorous acid gases from gas streams in coal gasification and biogas processing. It is also used in integrated gasification combined cycle systems and as a precursor for producing cenospheric oxide particles for gas purification.
