MgCl2
ceramic· MgCl2
Magnesium chloride (MgCl₂) is an inorganic ionic ceramic compound that exists primarily as a hydrated salt in industrial applications, though anhydrous forms are used in specialized contexts. It serves as a raw material and processing agent across chemical, construction, and de-icing industries, valued for its hygroscopic properties and ability to form stable complexes. Engineers select MgCl₂ for applications requiring chloride sources, magnesium ion release, or its capacity to modify material properties—such as dust suppression on unpaved roads, cement additives for magnesium oxychloride cements, and as an electrolyte precursor in magnesium extraction and battery technologies.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
