Summary Introduction
Dolomite is a common carbonate mineral with the chemical formula CaMg(CO₃)₂, primarily composed of calcium, magnesium, and carbonate ions. Its crystal structure belongs to the trigonal system, and the common crystal form is rhombohedral, with crystal faces often exhibiting a curved saddle shape. The color of dolomite ranges from pure white to gray, yellow, green, etc., depending on the type and amount of impurities present. The Mohs hardness of dolomite is approximately between 3.5 and 4, with a relative density of about 2.8 to 2.9.

Dolomite is a common carbonate mineral with the chemical formula CaMg(CO₃)₂, primarily composed of calcium, magnesium, and carbonate ions. Its crystal structure belongs to the trigonal system, and the common crystal form is rhombohedral, with crystal faces often exhibiting a curved saddle shape. The color of dolomite ranges from pure white to gray, yellow, green, etc., depending on the type and amount of impurities present. The Mohs hardness of dolomite is approximately between 3.5 and 4, with a relative density of about 2.8 to 2.9.
Dolomite has the following characteristics:
Chemical stability: It has good resistance to most acid and alkaline solutions at room temperature, but it will slowly fizz when encountering cold dilute hydrochloric acid.
Thermal stability: It decomposes when heated to 700-900℃, producing calcium oxide, magnesium oxide, and carbon dioxide.
Physical properties: It is brittle and can be easily scratched with iron tools.
Refractoriness: It has good fire resistance and is commonly used in refractory materials.
Application industries:
The applications of dolomite are very extensive, including but not limited to the following industries:
Metallurgical industry: Used as a flux and refractory material.
Chemical industry: Used in the production of calcium magnesium phosphate fertilizers, granular fertilizers, etc.
Building materials: Used in ceramics, glass formulations, and building stones.
Agriculture: Used as a soil conditioner to adjust soil pH.
Environmental protection industry: Used as a neutralizing agent in wastewater treatment.
Tourist attractions: Some dolomite rock formations have become tourist attractions.
Application in brake pads:
The application of dolomite in brake pads is mainly based on its chemical and physical properties. Brake pads need to withstand high temperatures and pressures, and the heat resistance and stability of dolomite make it an ideal additive. The specific functions are as follows:
Thermal stability: The high thermal stability of dolomite helps brake pads maintain structural integrity at high temperatures, reducing thermal fade.
Friction performance: The hardness and stability of dolomite help improve the friction coefficient of brake pads, providing stable braking effects.
Wear resistance: The hard particles of dolomite can enhance the wear resistance of brake pads, extending their service life.
Noise reduction: The addition of dolomite may help reduce vibrations during braking, thereby lowering brake noise.
Cost-effectiveness: As a common mineral, dolomite is relatively low in cost, helping to reduce the production costs of brake pads.
Overall, the application of dolomite in brake pads is primarily aimed at improving the heat resistance, friction performance, and wear resistance of the pads while controlling costs to ensure the reliability and safety of the braking system under various conditions.
