Calcined kaolin:

With the rapid development of science and technology, the requirements for materials in various industries are increasingly stringent. As a rare non-metallic mineral resource, calcined kaolin plays an indispensable role in many fields because of its unique physical and chemical properties. This article will take you into the world of calcined kaolin and explore its value and application.


First, kaolin and calcined kaolin


Kaolin, whose chemical formula is Al2O3·2SiO2·2H2O, is an important non-metallic mineral resource. After high temperature calcination, the water and volatiles in kaolin are removed to form calcined kaolin. Compared with raw ore, calcined kaolin has the characteristics of higher hardness and strength, lower thermal expansion coefficient and so on.


Second, the application of calcined kaolin


Ceramic industry: As the main raw material of ceramic products, calcined kaolin can improve the mechanical properties, heat resistance and insulation of ceramics. In the fields of electronics, aerospace and other fields, the demand for high-performance ceramic materials is growing, and calcined kaolin is indispensable.

Rubber industry: Calcined kaolin is used as a reinforcing agent and filler in the rubber industry, which can improve the wear resistance, tear resistance and tensile strength of rubber products. This makes rubber products widely used in automotive, machinery and other fields.

Paints and coatings: Calcined kaolin has excellent hiding power and whiteness, and can be used as pigments and fillers in paints and coatings. It helps to improve the anti-aging properties and decorative properties of the coating and extend the service life.

Medicine and health care: calcined kaolin has adsorbability and can be used in the production of drug carriers and health products. In the field of medicine, it can absorb toxic substances and reduce the side effects of drugs on the human body. In the field of health care products, calcined kaolin helps to regulate the acid-base balance of the human body and improve immunity.

Environmental protection: Calcined kaolin has excellent adsorption properties and ion exchange capacity, which can be used for sewage treatment and air purification. Calcined kaolin makes a positive contribution to environmental protection by absorbing and removing harmful substances from water as well as particulates and harmful gases from the air.


Third, production and market prospects of calcined kaolin


With the increasing demand for high-performance materials in various industries, the market demand for calcined kaolin has also shown a steady upward trend. In order to meet the market demand, countries have increased resources exploration and development efforts to improve the technical level of calcined kaolin production. At the same time, the company is also actively exploring new application areas to promote the sustainable development of the calcined kaolin industry.


In the future, with the progress of science and technology and industrial upgrading, the application prospect of calcined kaolin will be broader. With the joint efforts of various industries, we believe that the value of calcined kaolin will be more fully explored and make greater contributions to the progress and development of human society.
