· ZrSiO4

Zirconium silicate (ZrSiO₄) is a ceramic compound combining zirconium oxide and silica, forming a hard, refractory material valued for its thermal stability and chemical inertness. It is widely used in industrial applications requiring resistance to high temperatures, corrosion, and thermal shock, particularly in foundry operations, kiln linings, and specialized refractories. Engineers select ZrSiO₄ over alternative refractories where superior thermal conductivity combined with mechanical rigidity is needed without the risk of silica polymorphic inversion, making it especially relevant for precision casting molds and high-performance kiln 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.
