· Mg8 Si4 O16

Mg8Si4O16 is a magnesium silicate ceramic compound belonging to the pyroxene mineral family, characterized by a framework structure of silicate tetrahedra bonded with magnesium cations. This material is primarily encountered in geological and materials research contexts, where it serves as a model system for understanding silicate ceramics and their thermal, mechanical, and crystallographic behavior. Industrial applications leverage magnesium silicates in refractory linings, thermal insulation, and specialized ceramic composites; the specific stoichiometry Mg8Si4O16 is notable in high-temperature environments where thermal stability and moderate stiffness are required.

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.
