  Diamond Micron Powder / Nano Diamond Powder
Diamond micron powder is the fine size synthetic diamond powder,also called diamond polishing powder or diamond lapping powder,it used in lapping,polishing,finishing,super finishing for sapphire, gemstone polishing,quartz polishing,ceramic polishing, glass, natural diamond, electronic components and other hard materials polishing etc,our diamond micron powder also suitable for making polishing pads, polishing discs, diamond /PCD wire drawing dies, polishing paste, precision grinding disc, PCD&PDC composites.

We control the diamond powders by several type of particle size analyzers, this will guarantee our factory to supply our customer the micron powder of precise particle size distrubution.We can supply micron powder sizes according to cusomters' request or sample.

We continuously seeking innovations for diamond micron powder and diamond polishing powder products ,currently our diamond micron powders / diamond polishing powder products exported to foreign countries and areas with excellent polishing results from factories and workshops.Our diamond micron powders welcome by customers from Germany,USA,India,UK ,Belgium,Thailand,Korea,Japan etc.As a supplier and manufacturer diamond micron powder (diamond polishing powder) ,our products are of the following grain sizes: W0.5 (0-0.5 micron), W1.0 (0-1micron), W1.5 W2.5 W3.5 W5 W7 W10 W14 W20 W28 W40 W50 W60 / (M1,M1.6,~,M40) ,it also called 0-0.25,0-0.5,0-1,0.5-1,0.5-1.5,0-2,1-2,0.5-3,1-3,1.5-3,2-3,2-4,2-5,3-6,3-7,4-8,4-9,5-10,5-12,6-12,7-14,8-16,8-20,10-20,12-22,12-25,15-25,20-30,22-36,30-40,30-50,36-54,40-60,50-70,54-80 other wide range or narrow range size of diamond powder is available up on user's request.

Nano diamond powders, our nano grade diamond polishing powder / lapping powder / finishing powder is produced from the dissociative carbon in super high pressure and temperature during the detonation by the oxygen-negative explosive. The nano diamonds, with 5 - 20 nanometer basic sizes, have sphere shape and functional group of oxygen and nitrogen on the surface. It possesses characteristics of both diamond and nano functional material.
nanometer diamond is achieved from the dissociative carbon in super high pressure and temperature during the detonation by the Oxygen-deficient explosive. The nanometer diamonds, with 5 - 20 nanometer basic sizes, have sphere shape and functional group of oxygen and nitrogen on the surface. Specific surface area of nanometer diamond improves an order of magnitude more than common diamond. It possesses characteristics of both diamond and nanometer functional materials. 
Depending on requirements of different applications, nanometer diamond primary products should pass procedure of purification, surface modification and precise grading treatment, which are our exclusive technology. Different post-processing can separately achieve black powder products (containing graphite carbon layer on the surface) and pure grey nanometer diamond powder products; therefore, we can provide all series of nanometer diamond products with full specifications and types.
Nano diamond powders characteristics for Super finish polishing :
1. Stable high dispersibility
2. Various dispersible products
3. Characteristic anti-causticity.
4. High specific surface area,porous structure.
5. Superhigh purity, main element impurity below 30 ppm
6. Super polishing effect with minus 0.8 nm surface roughness
7. Characteristic surface modification treatment makes stable dispersion in both water & oil medium.
8. High electrical & thermal conductivity. Outstanding wearability, anti-causticity and thermal conductivity
9. Mature stable grading technics make our products suitable for all fields that ask for strict requirements of PSD.
10. Superhigh purity, main metal impurity below ppm, purification and surface modification treatment for different needs make surface functional group controllable.
11. Basic particles are sphere shape diamond crystal grains, which form stable specifications through secondary aggregation due to the features of nanoscale products and also possess the resistance & hardness of diamond.

Nano diamond polishing powders, TTD divided in hydrophilic and hydrophobic powder series, Water and Oil suspensions.
TTD

TTD nano diamond powders application field:
1. Precise polishing to achieve superfine surface smoothness;
2. Superfine surface treatment for the good texturing effect;
3. Precise grading for high removal rate of fine materials;
4. Widely used in the treatment of HDD, magnetic heads, semiconductors, gems, diamond, ceramics and exquisite industrial parts.

TTD nano diamond powders characteristics:
1. Good self-sharpness, which is similar to polycrystal diamond synthesized through conventional detonation impact;
2. Edgeless particles can effectively avoid scratches on workpieces;
3. Superpure without clusters;
4. Precisely graded with accurate PSD;
5. High removal rate, better finishes and less residual particles on workpieces.
