| Physical and Chemical Properties | Physical and chemical properties of diamond primary ore is only produced in the Hilbert tube or a small number of potassium magnesium lamprophyre. These are the parent rocks, and diamonds elsewhere are carried by rivers, glaciers, etc. Diamond is generally granular. If the diamond is heated to 1000 ° C., it slowly changes into graphite. The refractive index of diamond is very high, and the dispersion performance is also very strong, which is why the Diamond reflects a colorful flash. Diamond under X-ray irradiation will emit blue-green fluorescence. |
| Use | Use for enamel, etc. |

DIAMOND POWDER - Uses and methods of synthesis
Introduction
Diamond commonly known as "Diamond", that is, we often say that the diamond's original body, it is a mineral composed of carbon elements, is an allotrope of carbon elements. Diamond is the hardest substance naturally found in nature. Diamond has a variety of colors, from colorless to black, with colorless as the best. They may be transparent, or may be translucent or opaque.
nanodiamond
Nano Diamond, with the dual characteristics of Diamond and nano materials, not only has the ultra high hardness of diamond, good chemical stability and wear resistance, it also has a variety of characteristics, such as small size effect and macroscopic quantum tunneling effect, which are common to Nanomaterials. Its thermal, magnetic, optical and electrical characteristics are also different from those of normal particles, so that it can be used in machining, optics, biology, medicine and other fields have a wide range of applications, has become one of the hot spots in the world.
nanodiamond applications
nano-diamond not only has the comprehensive excellent characteristics of diamond, but also has good biological compatibility that is harmless to human body. It has great transmittance and absorption rate for radar wave and infrared light, excellent cold cathode field emission effect, there are many carboxyl, hydroxyl, carbonyl and other functional groups on the surface, it is easy to be closely combined with metal, rubber, plastic polymer surface and so on.
at present, Nano Diamond is mainly used in the following aspects:
① micro-Diamond CVD method synthesized by detonation is used to prepare diamond film; ② micro-Diamond is used to study chemical composite plating; ③ is used for lubricating oil, solid lubricant and lubricating coolant; ④ sintered body; (5) the possibility of being used in infrared and microwave absorbing materials; (6) being used in magnetic recording system; (7) being used in the catalysis of stealth materials; (8) adding nano-diamond to rubber and polymer can improve the performance; the addition of nano-diamond to the explosive can improve the explosive power.
synthesis method
at present, the methods of synthesizing nano-diamond mainly include: high temperature and high pressure method, solvothermal vapor deposition method, energetic particle irradiation method and detonation method.
among them, the detonation method is the most commonly used method. Compared with other synthesis methods, the personality is obviously more distinct and more suitable for modern industrial production, the preparation method is usually based on the explosive as the precursor (using TNT and RDX explosives as raw materials), that is, under the conditions of high temperature and high pressure at the instant of detonation, the use of negative oxygen balance explosive in detonation without oxidation of carbon atoms, through aggregation, crystallization and a series of physical and chemical processes, the formation of nano-scale carbon particle groups, including diamond phase, graphite Phase and amorphous carbon. The non-diamond carbon phase is removed with an oxidizing agent to obtain nano-diamond.
