application of barite
Drilling Industry:The overwhelming majority of the barite that is mind is used by the petroleum
industry as a weighting material in the formulation of drilling mud.Barite increases the hydrostatic
pressure of the drilling mud allowing it to compensate for high-pressure zones experienced during
drilling.The softness of the mineral also prevents it from damaging drilling tools during drilling and
enables it to serve as a lubricant.The American petroleum Institute(API) has established
specifications for the use of barite in drilling mud.
Medical Industry:An application where many people have heard of barite is within the medical field.
A high-purity form of barite is used in the gastrointestinal tract where its density prevents x-tay
penetration,and thus is visible on x-ray.The outline of the gastrointestinal tract thus becomes visible
allowing the determination of normal and abnormal antomy.
Other Uses: Barite is also used in a wide variety of other applications including plastics,clutch pads,
rubber mudflaps,mold release compounds,radiation shielding,television and computer monitors,
soune-deadening material in automobiles,traffic cones,brake linings,paint and golf balls.
