Similar Polycrystalline Diamond Micron Powder for Polishing

Similar Polycrystalline Diamond Micron Powder
Brand: HNHONGXIANG Diamond Powder
Type: HDYP diamond micro powder for precision polishing
Size: 2um to 100um
Usage: diamond polishing powder for silicon wafers, sapphire, engineering ceramics, tungsten carbide, glass, lens, etc.

Brief Introduction

Product Description

Similar polycrystalline diamond micro powders are produced by using chemically corrode monocrystalline diamond powder so that the diamond particle surface has different porosity characteristics of slight corrosion. The purpose is to increase the specific surface area of diamonds, and cause rough surfaces and improve self-sharpening and grinding efficiency, and effectively reduce cutting damage and scratches, improve the surface polishing quality.

Features:

  1. High Purity
  2. Cost-effective
  3. Long working Life
  4. Uniform crystal size
  5. High grinding efficiency;
  6. High self-sharpening ability;
  7. Concentrated particle size distribution

Size: 2um to 100um
Hot sale sizes: 3um, 6um, 9um, 22um, 30um.

Product Application

Application:

HDYP diamond micron powder ( similar polycrystalline diamond micro powder) is suitable for various kinds of bonded abrasives, coated abrasives, diamond lapping pastes, diamond suspensions, and other products.
Diamond powder to make diamond slurry for sapphire wafer polishing.
HDYP diamond polishing powder is mainly used in monocrystalline silicon, polycrystalline silicon, silicon wafers, sapphire, engineering ceramics, cover glass, and other materials. 
It has the characteristics of high efficiency and high precision grinding processing. Compared with HDP blasting polycrystalline diamond micro powder, it can be effectively replaced and has a great cost advantage.

Workpieces:
1. Silicon wafers, monocrystalline and polycrystalline silicon, semiconductor wafers, photovoltaic wafers；
2. Sapphire phone screen, sapphire mobile phone screen saver, camera sapphire screen protective film
3. Sapphire mobile phone camera protective film, mobile phone cover glass, sapphire watch mirror;
4. Precision cemented carbide, precision ceramics, optical glass and lens, etc.

Production Process

Particle Size Analysis

1.What is Particle Size Distribution (PSD)?
   Most individual grains of a diamond micro powder batch is not the same size (or shape).  The powder consists of a distribution of particles of different sizes represented as a frequency distribution curve.

2. In a Particle Size Distribution (PSD) curve, what do the terms Median, Mode, and Mean represent?
A:Median: the size where 50% of the particles is below/above that size
Mode: the size with the highest frequency (i.e. the greatest number of particles with the largest size)
Mean: the average size of the entire particle population.
 
Storage note:
The diamond powder should be stored in a dry environment to avoid the formation of clumps due to moisture in the powder. If the agglomeration of the fine powder will cause uneven mixing, bubbles or cracks will appear during heating and sintering, and defective products will appear.
If there is agglomeration, it is recommended to use low-temperature drying in blends.
