Bentonite powder has a wide range of industrial applications due to its unique physical and chemical properties. One of its primary uses is in the drilling industry, where it serves as a key component in drilling mud. The mud helps lubricate the drill bit, remove cuttings, and maintain pressure in the wellbore, ensuring smooth drilling operations.

In the foundry sector, bentonite powder is used as a binder in sand casting. It binds sand particles together, creating molds that can withstand high temperatures during metal casting. This application relies on bentonite's ability to form a cohesive structure when mixed with water.

Another important application is in the construction industry, particularly in civil engineering projects. It is used as a sealant in landfills and pond liners due to its low permeability, preventing the leakage of liquids. Bentonite powder is also added to concrete and mortar to improve their workability and waterproofing properties.

The cat litter industry extensively uses bentonite powder for its high absorbency. Its ability to clump when in contact with moisture makes it an effective material for controlling odors and simplifying waste removal. Additionally, in the oil and gas industry, it is used in well completion and stimulation processes to enhance reservoir productivity.
