Boron Carbide is one of the hardest materials known, ranking third behind diamond and cubic boron nitride.
- Extreme hardness, (Knoop 100g: 2900-3580 kg/mm2)
- Good chemical resistance
- Good nuclear properties
- Low density (2.52 g/cm2)
Due to the hardness, boron carbide powder is used as an abrasive in polishing and lapping applications.

As an acidic dispersion, Colloidal Alumina is a chemical-mechanical action, that provides superior surfaces on germanium, silicon, gallium arsenide, zinc sulphide, fluorides, sapphire, ferrite's and silicon carbide. Low scatter finishes can be obtained on pure metals such as nickel, tungsten, copper, beryllium, steel and aluminum. Epoxy resin materials and plastics have also been successfully polished with this versatile colloidal dispersion.
Properties: pH: 3 - 3.5; solids: 20%; viscosity: thixotropic.
Application: Depending upon the application, Colloidal Alumina can be used full strength or diluted. Dilution up to 1:1 or higher with deionized water is recommended. Polyurethane and short nap cloths are recommended. However, most commonly used laps and pads are compatible with colloidal alumina.

With great experience, technical knowledge, and modern facilities, we are able to manufacture superior diamond compounds and provide reliable service to every one.
Glennel® diamond products are specially formulated to help you prepare surfaces that are usually difficult to polish and require precision finish. To satisfy today's demand the diamond compounds must be complex with near perfect tolerances as is ours.
Types of Diamond:
We use three basic types of diamonds: natural monocrystalline, synthetic
synthetic polycrystalline. Typical sizes rangiefrom 1/10µm to 60µm
MONOCRYSTALLINE diamonds provide a cost effective means for good stock removal and finish. The natural form has a blocky shape with a smooth surface. Synthetic diamonds have a slightly irregular shape with multiple edges. Precision grading and high quality standards guarantee consistent shape and size. This consistency and unique shape make this a popular diamond for many production-lapping applications.
POLYCRYSTALLINE diamonds are recommended for microscopy, materialography, and where surface finish is extremely critical. We use the highest quality polycrystalline diamonds, Dupont Mypolex(r). It has a uniform blocky shape with a rough surface. Precision microfractures built into each particle provide uniform and consistent fracturing under stress.
Glennel® UB Formulation is excellent for most applications where a diamond compound is desired. It is soluble in either water or oil and works with all common extenders. UB compound is recommended for polishing laboratory specimens and lapping of materials such as carbide, ceramic, sapphire, composites, ferrite, and silicon.
Glennel® UC Formulation is an oil soluble compound recommended for finishing wire dies, molds, cold heading dies, and general shop applications where diamond compounds are required. UC provides fast cutting action and superior finish. Meant to be used with our Formula C extender for maximum efficiency.
Glennel® OS Formulation is an oil soluble compound designed for lapping large areas of hard material. Use alone or with an extender it cleans up easily, provides aggressive stock removal and an outstanding finish.
|Recommendations For Use||
|Finest finishes for work of the
highest precision. Used for optical,
metallographic, ferrite, laser rod,
and semiconductor finishing.
|Final finish for most applications: molds, dies, general flat lapping. Preparatory lapping. Intermediate finish to achieve dimensions.||3||2-4||8,000|
|Fast stock removal and roughing on hardest materials||45||36-54||325|
