Polished Substrates
 

We can provide various products design adapted to the polishing process of our customer: powder, slurry, paste, formulation. In the powders, we control the agglomerates to offer the best efficiency (integration of spray-dried products, fine alpha particles blended with gamma, agglomerates of alpha particles, isolated alpha particles…).

 

Especially for alumina, we can play on the size of the particles and the particle size distribution in order to fit the most closely with the required surface finish. We can also intervene on the alpha alumina rate into a gamma alumina matrix. In the case of formulations, we can play on other important parameters for polishing, such as viscosity, complementary to the abrasive efficiency.
 

For various substrates, we will play on abrasive properties of particles, choosing the nature of the abrasive (Zirconia, Ceria, Spinel…). JR delivers products to polish substrates such as:

*Ceramic. We can polish various ceramic substrates such as spinel pieces (see transparent ceramics).

Polished and unpolished sapphire for watch made with high purity alumina
*Crystal. For example, the sapphire: we can adapt the products according to the crystallographic face to polish. This substrate can be found in watchmaking and semiconductor industries.

*Glass. High performance glass parts can be polished with ceria-based slurries.

*Metal. Fine pieces for watchmaking, low thickness, requiring highly fine surface finish.

*Varnish & lacquer. Car polish is a well-known application, which requires pastes-type formulations, or at least high-viscosity products.
