Barium sulphate or Barium sulfate is a neutral chemical compound formed of barium and sulphate or sulfate ions. Typically, a chemical compound has sulfate or sulphate to its name when it consists of a sulphate anion which is a polyanion formed of sulfur and oxygen. The sulphate polyanion has the molecular formula as SO 4 2-and the electrical charge present on the sulphate anion is -3.

rheological behaviour of mango purée has been found to be ideal to avoid aspiration. It is palatable and well tolerated by most patients and is therefore used for x-ray visualization. Since the purée is not radiopaque barium sulphate is added. The addition of the barium sulphate, however, changes the experienced rheological properties.

BARIUM SULFATE is non-combustible and non-toxic. Emits toxic sulfur oxides when heated to decomposition. Can act as an oxidizing agent, but usually does not. Reacts with reducing agents such as potassium, phosphorus or aluminum (heating with aluminum can cause an explosion).

Barium also forms stable and slightly stronger complexes than radium, and this has been used widely in separating barium and radium via anion exchange. Radium sulphate is the most insoluble of the alkaline earth sulphates, and probably the most insoluble compound of radium known. Barium sulphate is such an excellent carrier for
