· JVASP-39261· K3Si

K3Si is a potassium silicate ceramic compound that belongs to the family of alkali silicates and is primarily of research and industrial interest rather than a widespread commercial material. It is employed in specialized applications requiring chemical stability and thermal resistance, particularly in glass manufacturing, ceramic binders, and advanced inorganic coatings where its silicate network structure provides durability. Engineers may specify K3Si-based systems for applications demanding alkali-resistant matrices or where the low density combined with moderate stiffness offers weight savings in composite reinforcement or thermal insulation contexts.

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.
