· ZnCr2O4

Zinc chromite (ZnCr₂O₄) is a dense spinel-structured ceramic compound combining zinc and chromium oxides, valued for its chemical stability and refractory properties at elevated temperatures. It is primarily used in refractory linings for metallurgical furnaces, kilns, and high-temperature industrial reactors where resistance to thermal shock and corrosive slag attack is critical. The material is also explored in pigment applications and as a corrosion-resistant coating in aggressive chemical environments, offering advantages over conventional refractories in specific thermal cycling scenarios.

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.
