Optimum Toughness Grains Brown Fused Alumina, suite Ad Abrasives Et Refractorie

Aluminium oxydatum Brown
BFA
Brown corundum

Brevis Descriptio

Brown Fused Alumina gignitur ex excoquunti Bauxite Calcined in fornace electrico in temperaturis plus quam 2000°C. Processus solidificationis tarda sequitur fusionem, ut crystallus obtusus cedat. Auxilium liquefactio ad tollendum residua sulphuris et carbonis , moderatio stricta super Titania gradus in fusione processus optimam duritiem granorum efficit.

Tum crudus refrigeratus ulterius tusus, magneticae immunditiae purgatur in magno intensione separatorum magneticarum, et in fractiones angustas magnitudine indicatur ad finem usui accommodatum. Lineae dedicatae producta pro diversis applicationibus efficiunt.

Applicationem

Brown Fused Alumina lenta est, abrasiva acuta, quae valde apta est ad stridorem metallorum magnae distrahendi vires. Eius possessiones scelerisque praestantem materiam usui praestant in fabricando productorum refractariis. Haec materia etiam in aliis medicamentis adhibetur, sicut uredine et induratione superficiei.
