Title:
バレル研磨用無機質メディア
Document Type and Number:
Japanese Patent JP5720903
Kind Code:
B2
Abstract:
Provided is an inorganic medium for barrel polishing, said inorganic medium enabling coarse finishing while exhibiting superior abrasion resistance. The inorganic medium for barrel polishing has a significant effect on costs and environmental impact because the sludge generated during barrel polishing is treated as industrial waste, as well as enabling coarse finishing and exhibiting superior abrasion resistance. In order to obtain the inorganic medium, a mixed material of argillaceous particulates and polishing particles is sintered. The inorganic medium contains at least 60-80wt% aluminium oxide, 10-30wt% silicon dioxide, 4-8wt% zirconium oxide, and 1-3wt% calcium oxide.
