Bentonite | CAS Number: 1302-78-9
Bentonite belongs to a class of clay minerals known as smectites. It is mainly composed of montmorillonite, a type of clay mineral, along with other minerals such as quartz, feldspar, and gypsum that are formed from the weathering of volcanic ash. The specific composition can vary depending on the source. The crystal structure of montmorillonite imparts certain unique characteristics to bentonite. It has a high surface area and is capable of absorbing and holding water molecules.

Application of Bentonite
- Swelling Properties: One of the most distinctive features of bentonite is its ability to swell and absorb water. When it comes into contact with water, the individual platelets in the clay structure separate, causing the clay to expand and swell. This property makes it valuable in certain applications.
- Drilling Fluids: Bentonite is commonly used in drilling fluids in the oil and gas industry. It helps to lubricate the drill bit, cool the drilling equipment, and remove drill cuttings.
- Foundry Industry: Bentonite is used as a bonding material in the preparation of molding sand for the production of metal castings.
- Food Industry: Bentonite is used in the food industry as a clarifying agent for beverages such as wine and fruit juices. It helps remove impurities and particles, improving the clarity of the final product.
- Environmental Cleanup: Bentonite is used in environmental applications, such as sealing or lining ponds and landfills to prevent the leakage of liquids.

About Bentonite
Bentonite is a naturally occurring clay mineral valued for its distinct physical and chemical properties. Our bentonite, sourced from leading bentonite powder manufacturers, guarantees superior purity and consistent quality in every batch, making it the go-to choice for those who demand reliability and performance.
A key characteristic of our bentonite is its remarkable swelling capacity. When exposed to water, it expands several times its original size, forming a dense, gel-like structure. This is thanks to its high montmorillonite content, a mineral known for its flexibility and adaptability. The swelling capability provides versatility, which makes this product highly regarded for industries that require a material that responds well to moisture.
Its swelling properties, our bentonite stands out for its adsorption and absorption abilities. Its unique molecular structure allows it to attract, bind, and retain a wide variety of substances, including ions, impurities, and gases. This makes it a highly effective material for industries that require efficiency in capturing and holding different particles. Its ability to act as both an absorbent and adsorbent ensures that it can adapt to different situations with ease.
Another notable quality of our bentonite is its outstanding rheological properties. When combined with liquids, it forms a smooth, stable gel that holds its structure while maintaining optimal viscosity. This ensures easy blending and excellent flow control, making it ideal for processes that require precision.
Our bentonite also offers exceptional thermal stability, maintaining its integrity even at high temperatures. This stability makes it suitable for use in environments where temperature fluctuations would typically affect material performance.
With a fine texture and minimal impurities, our bentonite is consistently uniform in quality, ensuring dependable results every time. For customers who need a material that balances performance with purity, our product is the trusted choice.
From swelling capacity to thermal stability, our bentonite is a top-tier material that continues to exceed expectations, brought to you by experienced bentonite powder manufacturers.
