Gisonite Application


Bentonite is a versatile and highly sought-after clay known for its unique absorbent properties. With its ability to swell and retain water, bentonite has found numerous applications across various industries.

What Is Bentonite?

In industrial settings, bentonite is commonly used as a binding agent in the production of foundry molds and pellets. Its exceptional binding capabilities make it an ideal choice for ensuring the structural integrity of these products.
Additionally, bentonite plays a crucial role in environmental remediation efforts. It is often utilized in soil liners for landfills and wastewater containment systems due to its ability to create impermeable barriers that prevent the migration of pollutants.

Moreover, it’s worth noting that bentonite offers several health benefits as well. When used topically, this clay can help soothe skin irritations and provide relief from conditions such as eczema or psoriasis. Internally, it has been used as a natural supplement to support digestive health due to its ability to bind toxins in the gastrointestinal tract.

Overall, bentonite’s impressive absorbent properties have made it an invaluable resource across various industries and provided numerous benefits for both industrial applications and personal health.
Bentonite consists of clay and minerals, mainly montmorillonite and minor beadlite. Most bentonites are formed by the weathering of volcanic ash and often in the presence of water. Bentonite has an aluminosilicate structure and is classified as a triple silicate.
Bentonite has two tetrahedral layers and one octahedral layer.

Types of Bentonite:

  • Calcium Bentonite
  • Sodium Bentonite
  • Montmorionite (acidic soil)

Calcium Bentonite

The use of Calcium Bentonite as a binder offers numerous advantages in foundry applications. Firstly, it provides good green strength to the mold, ensuring that it maintains its shape during handling and pouring of molten metal. Secondly, it helps in reducing mold-related defects such as veining and burn-on by promoting better flowability of molten metal within the mold cavity. Additionally, Calcium Bentonite exhibits high thermal stability which is vital for withstanding the extreme temperatures encountered during metal casting. It resists thermal expansion and contraction effectively while maintaining its structural integrity throughout the entire casting process. Furthermore, this versatile clay mineral can be easily controlled and adjusted to meet specific requirements of different casting processes. Its compatibility with various additives allows for customization of molding sands based on specific foundry needs.

Sodium bentonite

Sodium bentonite is a versatile and widely used natural clay that has numerous applications across various industries. With its unique properties and benefits, sodium bentonite has become an essential ingredient in many products and processes.

One of the key uses of sodium bentonite is in the field of drilling fluids. It is commonly added to drilling muds to enhance their viscosity, lubrication, and suspension properties. This allows for efficient drilling operations by preventing the collapse of boreholes and facilitating the removal of cuttings.

Another important application of sodium bentonite is in the construction industry. It is widely used as a sealing material for ponds, dams, canals, and other hydraulic structures. Due to its ability to swell and create an impermeable barrier when hydrated, sodium bentonite effectively prevents water seepage and leakage.

The agricultural sector also benefits from sodium bentonite’s unique characteristics. It is often used as a soil amendment to improve soil structure, water retention capacity, and nutrient availability. Sodium bentonite helps increase the productivity of agricultural lands by creating a favorable environment for plant growth.

Furthermore, sodium bentonite finds applications in wastewater treatment processes. Its high adsorption capacity enables it to effectively remove contaminants such as heavy metals from industrial effluents. This contributes to cleaner water resources and reduces environmental pollution.

Overall, sodium bentonite plays a crucial role in various industries due to its exceptional properties such as swelling ability, adsorption capacity, and sealing capabilities. Its versatility makes it an indispensable ingredient for numerous products and processes that contribute to the development of sustainable solutions in different sectors.


Types of bentonite:

Montmorionite bentonite is a highly versatile and widely used natural clay material that has numerous applications in various industries. Its unique properties make it an invaluable resource in fields ranging from construction and agriculture to cosmetics and pharmaceuticals.

One of the key characteristics of montmorionite bentonite is its exceptional water absorption capacity. This property allows it to swell and retain large amounts of water, making it an excellent additive for drilling fluids, soil conditioning, and erosion control. In the construction industry, montmorionite bentonite is commonly used as a binder in cement and concrete, enhancing their strength and durability.

In the agricultural sector, this clay material plays a crucial role as a soil amendment. Its ability to retain moisture helps improve soil structure, promote nutrient retention, and enhance plant growth. Furthermore, montmorionite bentonite serves as an effective carrier for fertilizers and pesticides, ensuring their controlled release over time.

The cosmetic industry also benefits greatly from montmorionite bentonite’s unique properties. It is commonly used in skincare products such as masks, cleansers, and exfoliators due to its ability to absorb excess oil and impurities from the skin. Additionally, its gentle exfoliating action helps remove dead skin cells, leaving the skin refreshed and rejuvenated.
