Sodium chlorate green plant parts. It can also kill through root absorption.

If used in combination with 2,4-D, performance is improved. Sodium chlorate has a soil sterilant effect. Mixing with other
Barium sulfate casting of copper anode plates. The anode plates are cast in copper molds, so to avoid the contact of the liquid copper and the solid copper mold, a solution of barium sulfate in water is used as a coating material on the mold surface. Thus when the liquid copper solidifies in form of an anode plate it can be easily released from its mold. Barium sulfate is sometimes used (or else PTFE) to coat the interior of integrating spheres due to the high reflectance of the material and near Lambertian characteristics. Almost all of the barium consumed commercially is obtained
