Application

Barium chromate serves a versatile purpose across various industries, primarily due to its properties as an oxidizing and corrosion-inhibiting agent. This heavy, yellow powder is utilized in safety matches and ignition control devices, functioning as a burn rate modifier in pyrotechnic compositions and delay fuses. Additionally, it acts as a catalyst in alkane dehydration reactions and plays a crucial role as a pigment and colorant in glass, ceramics, and porcelain. Its capacity to act as an effective corrosion inhibitor makes it invaluable in jointing pastes and metal primers, protecting against electro-chemical corrosion at metal junctions. In chromium electroplating baths, it serves as a sulfate scavenger, further highlighting its diverse range of applications.
