Basic properties of montmorillonite
Composition and origin of montmorillonite
Montmorillonite is a layered mineral composed of extremely fine particles of hydrous aluminosilicate, also known as jiaolingite and microcrystalline kaolinite. It is the main component of bentonite formed by the alteration of igneous rocks such as volcanic condensation rocks in an alkaline environment.
The shape and origin of montmorillonite
Form: Montmorillonite is mainly formed by the weathering of basic igneous rocks in an alkaline environment, and some are the products of the decomposition of volcanic ash deposited on the seabed. Montmorillonite is the main component of bentonite. Bentonite is produced in many places in my country, such as Liaoning, Heilongjiang, Jilin, Hebei, Henan, Zhejiang and other places. Most of the montmorillonite deposits with industrial value in my country are produced in the Mesozoic volcanic rock series.
Generally speaking, the appearance of montmorillonite refers to raw bentonite ore. Bentonite raw ore is often in the shape of earthy cryptocrystalline block, which is fine and scaly under the electron microscope. Generally speaking, the microscopic shape of montmorillonite refers to the crystal structure of montmorillonite.
Application fields of montmorillonite
Using its cation exchange properties to make montmorillonite organic complexes, it is widely used in high-temperature lubricating grease, rubber, plastics, and paints; using its adsorption properties, it can be used for refined cooking oil decolorization and detoxification, oil purification, nuclear waste treatment, and sewage treatment; It can be used as foundry sand binder by using its cohesiveness; it can be used in drilling mud by using its dispersing and suspending properties. Because many properties of sodium montmorillonite are superior to calcium montmorillonite, the cation exchange properties of montmorillonite are often used for modification treatment to transform calcium montmorillonite into sodium montmorillonite. Montmorillonite is widely used in medicine. It can be used as a pharmaceutical carrier and has the effect of a controlled release agent. In the field of medicine, there is a mature product, Montmorillonite Powder, which has almost become synonymous with Montmorillonite and has the effect of antidiarrheal. Montmorillonite is very well used in livestock (pig, rabbit) breeding, especially the yellow and white scours of piglets and suckling pigs, and diarrhea of rabbits. It has a preventive effect. In view of the characteristics of montmorillonite, it can also be used as the best The first choice of mold remover for feed. As a supplementary feed additive, montmorillonite has been widely used in the breeding of livestock and poultry abroad due to its natural properties and compound functions. In the United States, the use of montmorillonite as animal feed accounts for 2.14% of the total consumption, and it accounts for 5.47% in Armenia. It can not only compensate for animal nutrition, improve the production performance of livestock and poultry, but also regulate the flow of CP in the animal body, which is harmful to the prevention of digestive tract Disease plays a role.
FAQ
What is montmorillonite, and how does it relate to bentonite?
Montmorillonite is a layered mineral made up of extremely fine particles of hydrous aluminosilicate. It is formed primarily by the weathering and alteration of basic igneous rocks (such as volcanic condensation rocks or volcanic ash) in an alkaline environment. Montmorillonite is the primary active, microcrystalline component found within raw bentonite ore, which typically appears as an earthy block but shows a fine, scaly crystal structure under an electron microscope.
What are the primary industrial and agricultural applications of montmorillonite?
Because of its unique physical and chemical properties, montmorillonite is widely used across multiple fields:
Industrial Applications: Its cation exchange properties are used to make organic complexes for high-temperature greases, rubber, plastics, and paints; its adsorption properties make it ideal for purifying oil, refining/decolorizing cooking oil, treating sewage, and processing nuclear waste; its cohesiveness allows it to act as a foundry sand binder; and its dispersing/suspending properties make it highly effective in drilling mud.
Medicine & Animal Husbandry: In pharmaceuticals, it is used as a drug carrier, a controlled-release agent, and as an antidiarrheal powder. In livestock breeding, it functions as a natural feed additive and mold remover. It helps prevent digestive diseases—such as yellow and white scours in piglets and diarrhea in rabbits—while compensating for animal nutrition and improving livestock growth performance.
