   Description
 
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 which can polish hard materials efficiently.  Nortron is also highly recommended for lapping of ceramics 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.
