Mg(HO)2
ceramic· Mg(HO)2
Magnesium hydroxide [Mg(OH)₂] is an inorganic ceramic compound commonly produced as a fine white powder, widely used as a flame retardant additive in polymers, rubbers, and composite materials. It is employed in construction materials (fireproofing, fire-rated coatings), wastewater treatment (pH adjustment, heavy metal precipitation), and pharmaceutical applications (antacid formulations). Compared to halogenated flame retardants, Mg(OH)₂ is valued for producing minimal smoke and toxic gases when decomposed at elevated temperatures, making it the preferred choice in safety-critical applications where low-toxicity combustion products are essential.

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.
