Abstract

resumo produtos de terras diatomáceas de sílica cristalina reduzida e métodos de fabricação dos mesmos produtos de terras de diatomáceas com quantidades reduzidas de cristobalita e valores de y mais elevados são divulgados. os produtos de terras de diatomáceas são preparados de uma maneira convencional para produzir uma terra de diatomáceas calcinada por fundente. a terra de diatomáceas calcinada por fundente é misturada com hidróxido de potássio e a mistura é, em seguida, aquecida. a combinação do hidróxido de potássio e tratamento térmico pós-calcinação resulta em um produto de terra de diatomáceas com quantidades reduzidas de cristobalita e uma aparência mais branca, mais brilhante.
