The rough with the smooth

Abstract

"Therefore, all the countries that have a strong durable goods industry will demand more abrasives. Coated abrasives demand is also driven by repairs and maintenance besides durable goods," he added. "SiC is priced higher than BFA and typically higher than WFA and other white aluminas," Curimbaba explained, although other market sources said that SiC sits between BFA and WFA, with BFA being the lowest-price grade (see pp47-54). "This means countries rightly continue to ban the use of silica sand and are also making it difficult to cost-effectively dump the mineral's slag abrasives, which form the bulk of loose disposal abrasives, after use," the source added.
