· Mg1 O1

MgO (magnesium oxide) is an ionic ceramic compound belonging to the rock-salt crystal structure family, commonly known as periclase in its natural form. It is a wide-bandgap semiconductor with established applications in refractory materials, electrical insulators, and optical windows, valued for its high melting point, chemical stability, and transparency across infrared wavelengths. Engineers select MgO over alternatives like alumina in specialized thermal and optical applications where extreme temperature resistance, low thermal conductivity, or specific infrared transmission properties are critical.

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.
