BORON NITRIDE PASTE 
 
Weight: 150 gr.  
 
Content: wurtzite boron nitride powder (10/7 micron), 40% in water/alcohol soluble composition.

Properties: high thermal resistance and conductivity, dielectric strength (eliminates the risk of shorting out).
According to Ioffe Institute, thermal expansion of wurtzite boron nitride is the lowest among other materials, read more.

Grain size:  10/7 micron (see particle  size distribution diagram of wurtzite boron nitride powder)
  
Available on stock 

Application
Mold release, detaching and protective for high temperatures (up to 2000 °C), thermal  conductor. 

How it works: apply uniform layer; composition will evaporate under high temperature, leaving boron nitride on the surface; to some extent it's also stress resistant.

Why it's better:
- Thermal expansion of wurtzite boron nitride (according to Ioffe Institute) is approx. 1.5 lower than that of hexagonal boron nitride and consequently of other materials. Which means higher stability of coating layer under high temperatures.
-  Thermal conductivities of wurtzite crystal, parallel and perpendicular to the axis, are identical. Which means higher stability of thermal properties in comparison to hexagonal boron nitride.

DIAMOND POLISHING, LAPPING PASTE, CONCENTRATION 15%
 
Weight: 40 gr.  

Soluble in organic solvents.
 
Grain size: Please select from the list 

Diamond concentration: 15% by weight, or 30 ct. (6 gr.) of diamond in 40 gr. bottle. This is the highest concentration, which can be manufactured. 
If you need higher concentration, simply mix required quantity of diamond powder with any lubricant (oil, glycerol, etc.) 

Comparison of diamond weight in this paste and extra high concentration paste per 1 kg of product. 

0.25/0 Extra high 10% - 500 cts
0.25/0  15%                - 750 cts
0.5/0 Extra high 10%   - 500 cts  
0.5/0 15%                   - 750 cts  
1/0 Extra high 10%      - 500 cts  
1/0 15%                      - 750 cts   
 
Monocrystalline diamond powder.
   Micron diamond powders (grain size below 40 micron)  are monocrystalline by default. Yes. they may be obtained by milling of polycrystalline diamonds, but this hardy makes their crystal structure "poly", read more below. 
   Synthesis of polycrystalline diamonds: monocrystalline powders are pressed in a capsule, which then is exposed to high temperature and high pressure (HTHP synthesis), resulting, for example, in cutting inserts.
   Synthesis of monocrystalline diamonds: graphite powder and catalyst are pressed in a capsule, which then is exposed to high temperature and high pressure (HTHP synthesis). 
   To receive really polycrystalline diamonds  you need to use ultrafine micron powders (0.1/0 micron), obtained on super centrifuges in small amounts, because of high cost and comparatively low demand (e.g. for polishing of mirrors in space industry), so resulting crystals will be real agglomerates. But if you use powder 40 micron to make  polycrystal and then mill it, you will receive powder containing monocrystals 40 micron and finer, but not polycrystalline powder. 
   Milling of polycrystalline diamonds for pastes  does not make sense considering extra work and no benefits. Although defective diamond polycrystals are definitely milled.  Fairy tales about "more cutting surfaces per particle" of  diamond  "micron polycrystal"  were true about spiky diamond mono crystals synthesized on soviet presses long ago in a country far away. Presses, utilized now (American belt presses in South African E6 and Chinese cubic presses elsewhere) do not deploy synthesis profiles to make similar crystals. (Of course there are expensive exceptions :) )

DIAMONDSMILE DENTAL DIAMOND POLISHING PASTE, DIAMOND PASTE FOR DENTISTRY
 
Application
Smooth and high gloss polishing of any dental material (porcelain, composite materials, amalgam lithium-disilicate, zirconium oxide, veneering and hybrid ceramics, etc), for dental lab or clinic use.
Using a rubber cup, stiff bristle, or felt wheel, the pastes are used to polish the surface until an enamel-like finish is achieved.
 
Content: food grade glycerol, mint flavor, diamond powder, water. 
These water based pastes clean up with a quick water rinse.

Because the pastes contain insoluble content (diamond powder), which may enter the gastrointestinal tract, they are NOT recommended for work directly in patient's mouth.  

Weight: 10 gr.

Application
  The best cost/productivity ratio for finishing and polishing  of  ferrous, non-ferrous metals, stainless steel, hardened and alloyed steels.  

CBN (cubic boron nitride) is a generic name, there are other trade marks of this material: elbor, borazon, cubonite, etc. 
CBN is softer comparing to diamond, the reason is shape of crystal: 
- CBN has crystal structure   of an octahedron - the number of cutting edges are larger with less sharper corners, while
- diamond has   crystal structure of a tetrahedron - there  are fewer cutting edges with sharper corners.
