Diamond micro-powder is mainly divided into polycrystalline diamond micro-powder, single crystal diamond micro-powder, and nano diamond micro-powder. This article will delve into the types and applications of these three kinds of diamond micro-powder.
Polycrystalline diamond micro-powder is synthesized under the strong impact wave generated by an explosion using nano crystals. This type of diamond micro-powder mainly exists in micrometer and submicron polycrystalline structures, featuring isotropy, no cleavage planes, and exhibiting excellent impact resistance and flexural strength. Due to its unique physical properties, polycrystalline diamond micro-powder is widely used in high-tech industries and traditional pillar industries.
In the field of high-precision processing, polycrystalline diamond micro-powder is mainly used for ultra-fine processing of chip learning crystals, ultra-precision polishing of large silicon wafers, and surface modification. Its grey-black spherical appearance with a slight metallic sheen not only provides strong functionality in industrial applications but also possesses a unique aesthetic appeal. Its high hardness and high toughness make polycrystalline diamond micro-powder perform excellently in these applications, significantly improving processing accuracy and surface smoothness of materials.
Single crystal diamond micro-powder has regular crystal shapes, usually cubic or octahedral, with very high strength and toughness, excellent thermal stability, and impact resistance. Thanks to these superior physical properties, single crystal diamond micro-powder is widely used in manufacturing electroplated products, grinding wheels, and abrasive wheels.
Additionally, single crystal diamond micro-powder is extensively used in the polishing and carving of high-end stone materials, as well as in the processing of automotive glass, high-end furniture, ceramics, hard alloys, and magnetic materials. These application fields require very high hardness and precision of materials, and single crystal diamond micro-powder can meet these demands. Its outstanding wear resistance and stability make it perform excellently in various high-demand processing tasks, providing strong support for high-quality processing.
Nano diamond micro-powder is a new material synthesized using explosive techniques in recent years. It is nano-sized, typically one billionth of a meter, with small size effects, large specific surface area effects, and quantum size effects. These properties make nano diamond micro-powder perform excellently in various high-tech fields.
Firstly, nano diamond micro-powder plays an important role in the preparation of advanced polishing pastes and polishing fluids. It is used for ultra-precision machining of quartz, optical glass, semiconductors, alloy and metal surfaces, significantly improving processing precision and meeting high-end industrial demands. Secondly, nano diamond micro-powder is also used in the preparation of catalysts. Its large specific surface area and diverse surface functional groups make it perform excellently in catalytic reactions, promoting the reaction of organic compounds and improving catalytic activity.
Moreover, nano diamond micro-powder also has important applications in the preparation of nano-composite structural materials. By combining nano diamond with nano silicon powder, nano ceramics, and various nano metals, new types of nano-structure materials can be manufactured. These materials are widely used in semiconductor devices, integrated circuit components, and microcomputer parts, promoting advancements in related technologies due to their unique properties.
