· O12 Na2 Al2 Si4

O12 Na2 Al2 Si4 is a sodium aluminosilicate ceramic compound, a member of the feldspathoid family of silicate ceramics commonly found in porcelain, glass-ceramics, and traditional ceramic formulations. This material is widely used in industrial ceramics and glass-ceramic systems where alkali-containing silicates provide melting assistance, thermal shock resistance, and controlled microstructure development; it is valued in applications requiring thermal stability and chemical durability, particularly where lower processing temperatures or improved crack resistance are advantageous compared to pure silicate systems.

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.
