Abstract

Микропористая керамическая фильтровальная пластина (22) капиллярного действия выполнена из рекристаллизованного карбида кремния, т.е. чистого карбида кремния. Карбид кремния (SiC), также известный как карборунд, представляет собой соединение кремния и углерода с химической формулой SiC. Зерна карбида кремния могут быть соединены друг с другом при повышенных температурах с образованием очень прочной керамики. В отличие от других типов материалов на основе карбида кремния, в которых используются добавки (связующие), чтобы помочь склеивать вместе частицы карбида кремния, керамика из рекристаллизованного карбида кремния изготовлена из чистого порошка из карбида кремния, имеющего бимодальное распределение частиц по размерам, например чрезвычайно мелкие и крупные зерна. Фильтровальная пластина на основе чистого кристаллизованного карбида кремния является чрезвычайно коррозионно-стойким материалом, который обеспечивает значительно более длительный срок службы фильтровальной пластины также при использовании при фильтрации, когда присутствует фтор.The microporous ceramic filter plate (22) of capillary action is made of recrystallized silicon carbide, i.e. pure silicon carbide. Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with the chemical formula SiC. Silicon carbide grains can be bonded together at elevated temperatures to form highly durable ceramics. Unlike other types of silicon carbide-based materials that use additives (binders) to help glue silicon carbide particles together, recrystallized silicon carbide ceramics are made from pure silicon carbide powder that has a bimodal particle size distribution, such as extremely small and large grains. A pure crystallized silicon carbide filter plate is an extremely corrosion-resistant material that provides a much longer service life of the filter plate also when used during filtration when fluoride is present.
