Overview

Chromic Acid is also known as Chromium Trioxide or Chromic Anhydride. It is hygroscopic in nature and forms a saturated solution of 62.6% CrO3 at 25C. Though it is an acid, a diluted solution of it exerts a protective action on the metal surfaces like mild steel, zinc, aluminum, copper, brass, etc at room temperature, by the formation of a thin passive film.

At Lords we have a sophisticated flaker machine and also a temperature control device which are in compliance with the stringent quality standards. Sodium Dichromate which is required in the production of Chromic acid is also produced by Lords chemicals and thus helps in ensuring a high and consistent quality of Chromic acid.
