Kalcijum hromat (CaCrO4) je svetlo žuta čvrsta materija. Normalno se javlja kao dihidrat.

Kalcijum hromat gubi vodu na 200 °C. Kalcijum hromat reaguje sa organskim materijama ili redukujućim agensima da formira hrom(III). Kalcijum hromat eksplozivno reaguje sa hidrazinom. Ako se pomeša sa borom i zapali, dolazi do burnog formiranja hromata.[3]

On se koristi kao pigment i inhibitor korozije. On isto tako nalazi primenu u galvanizaciji, fotohemijskoj obradi i industrijskom tretmanu otpada.
