Rath Acrath - Acid-Resistant Stones

Acrath bricks are acid-resistant, classified as either Class 1 (Acrath S1-t) or Class 3 (Acrath S3-t).
These bricks are resistant to many chemical attack types, especially acidic furnace exhaust gases and sulfur compounds, even when the dew point is reached. They are therefore used for acid-resistant linings. Their high abrasion and chlorine resistance make them ideal for use in fluidized bed systems and preheaters in the cement industry, where raw materials or fuels contain such substances.
