· MgCO3

Magnesium carbonate (MgCO3) is an inorganic ceramic compound commonly found in nature as the mineral magnesite, valued for its chemical stability and thermal properties. It is widely used as a filler and reinforcement agent in rubber and plastic compounds, as a refractory material in high-temperature applications, and in pharmaceutical and food processing industries where it serves as an anti-caking agent and dietary supplement. Engineers choose MgCO3 over alternatives like calcium carbonate when thermal stability, lower density, or specific chemical inertness is required, though its brittleness and moderate strength limit it to non-structural roles in most applications.

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.
