IBI Diamonds manufacturing process controls the micron diamond powder from beginning to end: adequate raw material selection, crushing and processing, purification, pre-grading and precision grading by means of automated equipment. This results in perfect size distribution consistency. Particle shape deserves particular attention: it has to be consistently blocky, whilst retaining sharp cutting edges and rough particle surfaces for good retention. You will notice no difference between one delivery and the next.

With our latest advanced technology we are able to produce different grades of diamonds which suit most applications. Very strict process controls lead to a consistent premium quality of synthetic diamond powder. Our diamonds which are manufactured by the resin metal bond system are available in various grades and sizes. Along with the mesh sized diamonds of different hardness they are all in compliance with the US-Standards. The metal-bond diamonds are also available with copper or nickel coating

Polycrystalline diamond is highly friable diamond with multi edge system of hundreds of crystals, It is recommended for applications when material removal rate and/or surface finish are more important than processing costs, and if it is impossible to achieve good quality in any other way. The table below gives an overall picture of the composition of the structure and its characteristics.
IBI Polycrystalline Diamond Powder
Appearance
Dark grey to black in colour.

Particle structure
Formed by explosion synthesis. Each diamond particle consists of countless microcrystallites, about 20 nanometers in size. Polycrystalline diamond features no cleavage planes, which makes the particles tougher, compared to monocrystalline particles.

Characteristics
Polycrystaline diamond is particularly suited for high-performance lapping applications.
Thanks to its polycrystalline structure without cleavage planes, it is considerably stronger than monocrystalline diamond. This allows for higher process pressures and thus increased material removal rates in lapping applications.



Typical applications
Lapping of:
   - sapphire
   - ceramic oxides
   - tungsten carbide
   - composite materials

In certain applications, natural diamond.offers a useful option, despite the higher cost. Natural diamond shares the monocrystalline structure of its synthetic equivalent, but the absence of the metallic catalyst used for synthetic diamond production gives it some particular properties: better defined cleavage planes and a reduced electric conductivity. It is therefore preferred in selected applications requiring very free cutting properties. It is also used in the manufacture of some electrometallic tools and wheels.
IBI Natural Diamond Powder
Appearance
Natural diamond is white to light grey and beige.

Particle structure
Natural diamond has a monocrystalline particle structure, created by high pressures and temperatures underground. Like synthetic monocrystalline diamond, it features major cleavage planes, which are oriented parallel to the optical axis. Natural diamond particles break relatively easy parallel to the cleavage planes.

Characteristics
Natural diamond is precision graded and has a blocky, sharp-edged particle shape. It is free of catalyst metals, which makes it the preferred choice for plated tools and other applications requiring maximum cleanliness. Natural diamond is also used in lapping and polishing processes with special requirements.


Typical applications
Tools and surface applications:
   - plated diamond tools
   - grinding wheels
   - dental tools
   - pellets

Lapping and polishing of:
   - wire drawing dies
   - special applications

Boron Carbide is a high performance abrasive material with chemical and physical properties similar to diamonds, such as, chemical resistance and hardness. Boron carbides extra hardness gives it the nickname "Black Diamond" (It ranks third after diamond and boron nitride) and is one of the leading grinding materials.
IBI Boron Carbide
Application examples
   - Grinding, lapping and polishing tungsten carbide and other hard materials such as different types of ceramics,
     minerals, glasses, etc
   - Hot pressing and sintering of the hard and abrasion resistant parts with super light weight.
   - Metallurgical refractory with high corrosion and oxygen resistance.
   - Neutron absorbing materials for nuclear technology.
   - Additive for sintering silicon carbide parts and diamond tools.
   - Steel modification component with high boron content.
