The particlesproduced by the process are flat and tend to lie parallel with thesurface being worked; the working pressure is thus more evenlyspread. Breakdown of the abrasive is reduced and abrasiveness is retained for a longer period.

2 The close gradingof Logitech Calcined Aluminium Oxide Powders provides theoptimum combination of cutting rate and surface following advantages can be obtained using LogitechCalcined Aluminium Oxide Powders:Faster Lapping & Polishing- Experience has shown that thesepowders can usually reduce lapping and polishing times by atleast 20% and are particularly effective on hard materials, , silicon and hardened steel (other abrasives have atendency to be crushed and break down too quickly). In someinstances 50% reductions in time have been achieved overconventional powders because a larger particle size may beused without loss of surface in Concentration of Abrasive Slurry - Normally theconcentration of abrasive in a slurry may be reduced by at least25% when changing to Logitech Calcined Aluminium OxideAbrasive Powder from regular alumina Pressure and Plate Speed can be increased - Pressureand plate speed used for lapping can, in most cases, beincreased by up to 10% after changing to Logitech, CalcinedAluminium Oxide Abrasive Powder from regular aluminaabrasives.

3 Thus reducing lapping take full advantage of Logitech Calcined Aluminium OxidePowder, reference should be made to the particle distributioncurves overleaf, thus enabling a Powder which has a larger aver-age particle size than the abrasive currently in use to be example, if a 500 grit (12 micron mean) regular aluminiumoxide Powder is currently used, then it should be replaced with20 micron Logitech Calcined Aluminium Oxide Powder . In eachof the instances noted, surface finish will be relativelyunchanged, due to the lower apparent particle size of theCalcined Aluminium Oxide , resulting from their flatter shapewhen compared to conventional regular Aluminium Oxide abra-sive properties:Hardness, MohProduct typeColourShapeSpecific g/ccAluminium Oxide PowderooLogitech LimitedErskine Ferry Road, Old Kilpatrick, Glasgow G60 5EU, Scotland, : +44 (0) 1389 875444 Fax: +44 (0) 1389 890956e-mail: by:Certificate 12025 Typical Chemical Analysis (3 micron) < on products:Ethane DiolOrdering Data.
