Saint-Gobain has developed a water-based alpha alumina and diamond slurry which has proven itself to be an excellent polishing agent for hard materials. It can be used to produce superior surface finishes on electronic components and wear parts made of tungsten carbide, silicon carbide and other advanced structural ceramic materials. Our Research and Development group determined that if fine polishing diamond is added to nanometer sized alpha alumina, there is a synergy between the two polishing agents. The result is Nortron Polishing Slurry that can polish hard materials efficiently. Nortron is highly recommended for lapping and polishing of ceramics, crystals and sapphire.

Physical Characteristics

Nortron Polishing Slurry is comprised of individual crystallites of nanometer sized alpha phase alumina in precise proportion with discreetly sized fine diamond powder. A pH of 10.0 - 10.5 is maintained for maximum performance.

The presence of the alumina material also permits effective recirculation of Nortron Polishing Slurry.

Designed for lapping and polishing ceramics and sapphire, Saint-Gobain Surface Conditioning's oil-based slurries are made from highly refined, precision-graded diamond powders. The O854 series provides aggressive cutting action during lapping, with lubricants to help reduce scratching and damage to the work piece. Safe to work with, Saint-Gobain’s oil-based slurries comply with EPA and OSHA requirements.

• O854BS Slurry

Saint-Gobain O854BS is a unique diamond suspension slurry that can suspend very coarse particles at a relatively low viscosity. It provides a fast material removal rate and controlled surface finish.
 

• O856LVS Slurry

Saint-Gobain O856LVS is a semi-suspension, oil-based diamond slurry that produces a superior surface finish when lapping and polishing ceramics and other hard materials. O856LVS can semi-suspend up to 50 µm diamond and works particularly well on harder plates such as cast iron.

• O854US Slurry

Saint-Gobain O854US is designed specifically for lapping of sapphire on copper plates. A low viscosity slurry, O854US earns rave reviews from customers for its unique suspension properties and aggressive cutting action.

• Benefits
  • Precision-graded and high surface purity diamond
  • Provides excellent wetting and spreading of slurry during lapping
  • Provides fast material removal rate and controlled surface finish
  • Unique low viscosity diamond suspension slurry
  • Field tested and industry approved
  • Knowledgeable application engineers available for technical support

• W768 Slurries

Saint-Gobain’s W768 slurry line features cut-rate enhancers for aggressive cutting action during lapping along with lubricants that help reduce scratching and sub-surface damage to the work piece.

• BLC40 Slurry

Saint-Gobain’s BLC 40 slurry features unique suspension additives that easily disperse diamond particles through electrostatic repulsion. BLC40 is specially formulated with environmentally friendly lubricants that produce a very smooth surface after lapping.

• W809 Slurries

Saint-Gobain Surface Conditioning's W809 series of water-based diamond suspension slurries feature additives that prevent agglomeration of particles which helps to minimize scratches, and cut-rate enhancers for aggressive cutting action. W809 slurries can achieve below 10 A surface roughness on single crystal substrates, making them ideal for use before the final CMP step.

• W809HNS

Is designed for pre-polishing wafers such as GaN and other hard crystals before CMP.

• Benefits
  • Provides excellent wetting and spreading of slurry during the lapping process
  • Reliable performance and user-friendly for high volume manufacturing processes
  • Keeps the plate running cool during lapping, making it ideal for high volume lapping operation
  • Provides fast material removal rate and controlled surface finish
  • Field tested and industry approved
  • Contains no petroleum distillates
  • Knowledgeable application engineers available for technical support
