The Most Exported Types of Bentonite in 2025
Bentonite is a versatile clay used in many industries, including construction, oil drilling, agriculture, and environmental services. Its unique properties make it an essential material in various applications around the world. In this article, we’ll explore the most exported types of bentonite and why they’re in high demand across different countries.
The Two Main Types of Bentonite: Sodium and Calcium
Bentonite comes in two main types: sodium bentonite and calcium bentonite. Each type has different properties, making them suitable for specific industries. Both are in high demand and are the most commonly exported types of bentonite.
Sodium Bentonite – The Leading Export
Sodium bentonite is the most widely exported type of bentonite. Its key feature is its ability to expand and form a gel when mixed with water. This makes it perfect for the oil and gas industries, where it’s used as drilling mud to stabilize boreholes and prevent the collapse of wells.
Countries like the United States, China, and India are major producers and exporters of sodium bentonite. The growing global demand for oil and gas, particularly from unconventional sources like shale oil, continues to drive up the need for sodium bentonite in drilling operations.
Aside from oil and gas, sodium bentonite is also used in civil engineering, foundries, and environmental applications such as sealing ponds and landfills. Its wide range of uses makes it the most exported type of bentonite.
Calcium Bentonite – A Rising Export
Calcium bentonite is also in high demand, especially for industries such as agriculture, pet care, and environmental management. This type of bentonite doesn’t swell as much as sodium bentonite, but it’s still highly absorbent. It’s mainly used to improve soil quality and is also a key ingredient in cat litter products.
In agriculture, calcium bentonite helps retain moisture in the soil, making it an important tool for farmers. It’s also used as a feed supplement for livestock. In pet care, calcium bentonite is used in high-quality cat litter to absorb moisture and control odors.
Countries like the United States, Greece, and Turkey are top exporters of calcium bentonite. As global agriculture and pet care industries continue to grow, the demand for calcium bentonite is expected to rise, particularly in emerging markets.
Why Are Sodium and Calcium Bentonite So Popular?
The demand for sodium and calcium bentonite is driven by their widespread uses in essential industries. Both types are crucial for several sectors, and their versatility makes them valuable exports.
Oil and Gas Industry Growth
Sodium bentonite is particularly important in the oil and gas industry. As companies continue to explore new oil and gas reserves, especially in unconventional areas, the need for sodium bentonite in drilling processes increases. Its ability to stabilize the drilling mud and seal boreholes makes it a must-have for oil exploration.
Expanding Agriculture and Pet Care Markets
The growing demand for sustainable farming and the rise in global pet ownership are also driving the export of calcium bentonite. Its use in agriculture to improve soil retention and in pet care for high-quality cat litter is gaining popularity as more people seek eco-friendly and efficient solutions.
