Industrial Synthetic Resin Bond Diamond Micron Powder Grade BRM

0.5-60um Light Gray Industrial Diamond Powder ISO9001

Description:

Diamond is a mineral composed of carbon. It is an allotrope of graphite with a chemical formula of C. It is also the original body of common diamonds. Diamond is the hardest substance naturally occurring in nature. Graphite can form synthetic diamonds under high temperature and high pressure. Diamond has a wide range of uses, such as handicrafts, cutting tools in industry, and it is also a precious gemstone.
Diamonds come in various colors, from colorless to black, with colorless ones being particularly preferred. They can be transparent, translucent or opaque. Many diamonds are yellowish, which is mainly due to impurities in the diamonds. The refractive index of diamond is very high, and the dispersion performance is also very strong, which is why the diamond reflects colorful flashes. Diamond will emit blue-green fluorescence under X-ray irradiation. The primary diamond ore is only produced in the Kimberlite tube or a few lamprophyre rocks. Kimberlite is their parent rock, and diamonds in other places are transported by rivers and glaciers. Diamond is generally granular. If the diamond is heated to 1000°C, it will slowly turn into graphite.

There are two main methods of synthetic diamond, high temperature and high pressure method and chemical vapor deposition method.
The high temperature and high pressure method technology has been very mature and has formed an industry. The domestic output is extremely high, the highest in the world. The chemical vapor deposition method still mainly exists in the laboratory.

Optical Properties of Diamond:
1) Brilliance diamond has extremely high reflectivity, its reflection critical angle is small, the range of total reflection is wide, light is prone to total reflection, and the amount of reflected light is large, thus producing high brightness.
(2) Scintillation: The flicker of diamond is flash, that is, the reflection and flash of white light on its surface when the diamond or the light source and the observer move relatively. Colorless, transparent, well-crystallized octahedron or curved poly-shaped diamond, even without cutting and grinding, it can show good flashing light.
(3) Dispersion or fire: Diamond's diverse crystal faces are like a prism, which can decompose the white light that enters the crystal through refraction, reflection and total reflection into the constituent colors of white light-red, orange, yellow, green, Blue, indigo, purple and other shades.
(4) Luster: The outstandingly hard, smooth and shiny crystal surface or cleavage surface of corundum has a particularly strong reflection effect on white light, and this very characteristic reflection effect is called diamond luster.

Series of Harmony Resin Bond Diamond Powder

-Resin Bond Diamond Micron Powder Grade BRM

Description: Resin bond diamond micron powder with light gray color, blocky shape, friable, multicrystalline struture. Size distribution and shape are controlled tightly. RBM offers excellent performances in polishing and lapping glass, ceramics etc.

Characteristics:

Strong cutting force: There are a large number of sharp cutting edges on the surface of particles, and the cutting force can reach 2-4 times that of single crystal diamond powder.
High polishing accuracy: The cutting edge of single crystal diamond powder is large and hard, which is prone to deep scratches. The cutting edge of polycrystal-like diamond powder is small and its hardness is low. The Ra value of workpiece surface after polishing decreases significantly.
Strong grip strength: rough surface of particles and stronger bonding with binder can significantly improve grip strength of abrasives in various diamond products and improve service life.
