鑽石 Diamond

Universal material for industry-Diamond

Catalogue

When it comes to manufacturing and processing high-precision parts, abrasives are very important materials in grinding technology, and are often used to study materials for industrial processes such as grinding and cutting. There are many types of abrasives, and each abrasive has its own unique characteristics and application range. When selecting abrasives, it is necessary to consider the characteristics of the processing material, the required processing concentration and surface quality, as well as the temperature and pressure during the grinding process, etc. factor. Correct selection and use of abrasives can improve processing efficiency and finished product quality, and reduce cost and time. In this article, we will discuss the feature of diamond as an abrasive material and its application in machining.

Element

It is the original body of diamond, a mineral composed of carbon, and its chemical formula is C. In nature, diamond is formed in the high-temperature and high-pressure environment deep in the earth. It is one of the hardest substances on the earth, with a hardness of 10 on the Mohs scale.

Preparation

1. High temperature and high pressure method

It is a method of naturally preparing diamonds, which needs to be carried out under high temperature and high pressure environment.

2. Chemical vapor deposition method

It is a method of artificially preparing diamond, which deposits carbon atoms on the substrate through a chemical reaction to form a diamond film.

Feature

FeatureDirectionsApply to
Extremely High HardnessThe hardest natural material, it can scratch and cut through virtually any other material.Cutting Tools and Abrasives.
High thermal conductivityCan transfer heat quickly.Applications requiring rapid heat dissipation.
High ConductivityAlthough diamond itself is not a good electrical conductor, it becomes a high-performance electrical conductor after speculation or modification of properties.Electronic field.
Optical TransparencyTransparent to most wavelengths of light while having a very high index of refraction.Plays an important role in the manufacture of optical applications such as lenses, cylinders and windows.
Chemical StabilityHigh stability and corrosion resistance to most chemical substances, less affected by acids and alkalis.Chemical processing.

Type

TypeDiamond DADiamond BA
Raw MaterialMade of diamond powder as raw material.Made from cubic boron nitride (CBN) powder.
Feature1. Has extremely high hardness and wear resistance.
2. Ideal for cutting tools, molds and precision parts that require high hardness and durability.
1. Hardness and wear resistance are slightly lower than diamond.
2. Compared with traditional abrasive materials, the hardness still has superior performance.
Apply toMetal processing, glass processing and other precision processing.1. Hard and brittle materials such as ceramics, glass, semiconductors, etc.
2. Difficult-to-machine metals such as high-speed steel and hardened steel.

Chemical Properties

1. Brilliance

It has extremely high reflectivity, its critical angle of reflection is small, the range of total reflection is wide, light is prone to total reflection, and the amount of reflected light is large, resulting in high brightness.

2. Scintillation

The reflection and glint of white light on the surface of the diamond or the light source and the observer as they move relative to each other. A colorless, transparent, well-crystallized octahedral or polyhedral diamond that exhibits good scintillation even without cutting.

3. Dispersionorfire

The crystal face, like the three enamels, can decompose the white light entering the crystal through refraction, reflection and total reflection into the constituent colors of white light-red, orange, yellow, green, blue, indigo, purple and other colored lights.

4. Luster

The eminently hard, flat and bright crystal face or cleavage face of corundum has a particularly strong reflection effect on white light.

Application

1. Cutting and grinding tools

Its extreme hardness makes it an ideal tool for cutting and grinding, and it is widely used in jewelry, industrial materials and semiconductor manufacturing. Diamond cutting and grinding tools perform tasks more efficiently and precisely, reducing production costs and waste.

2. Abrasive processing

It is widely used for grinding, polishing and dressing the surface of materials, and can process materials of various hardness with extremely high efficiency and precision.

3. Optical components

Is a transparent material used to make optical components such as laser windows, fiber couplers and optical amplifiers.

4. Electronic devices

High thermal conductivity and high insulation make it an ideal material for electronic devices such as transistors, diodes and photosensors.

5. Biomedical

With good biocompatibility and chemical stability, it is used in the field of biomedicine, and can be used to manufacture artificial joints, artificial heart valves and dental implants.

6. Energy mining

It can be used for drilling and workover in oil, natural gas and geothermal exploitation, which can improve production efficiency and reduce drilling cost.

Conclusion

Diamond is a material with a very wide range of applications. Its high hardness and excellent thermal conductivity make it play a vital role in industrial and technological fields, such as cutting tools, electronic devices, etc. Diamond is also an extremely popular gemstone for jewelry, and its extreme hardness and optical properties make it ideal for high-quality jewelry. Although diamond has many excellent properties, it also faces some challenges, such as high cost and complicated manufacturing process. In the future, with the development of new technologies and materials, diamonds will continue to play an important role in various fields and bring more innovations and breakthroughs to mankind.
