K2CrO4
ceramic· K2CrO4
Potassium chromate (K2CrO4) is an inorganic ionic ceramic compound consisting of potassium cations and chromate anions, commonly encountered as a yellow crystalline solid. It is primarily used in analytical chemistry, metal surface treatment, and corrosion inhibition applications, where its strong oxidizing properties and chromate functionality provide protection against rust and enable detection reactions in laboratory settings. Engineers select K2CrO4 for corrosion-inhibiting coatings and conversion treatments on steel and other metals, though its use is increasingly restricted in some regions due to environmental and health regulations favoring less toxic alternatives.

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.
