Question:

Are insulating fire bricks resistant to phosphoric acid?

Answer:

Phosphoric acid, being a strong acid, has the potential to react with and corrode various materials, including fire bricks. Although certain fire bricks may possess a degree of resistance to acidic conditions, insulating fire bricks are generally not equipped to endure prolonged exposure to phosphoric acid without experiencing notable deterioration. As a result, it is advisable to employ acid-resistant materials like acid-resistant bricks or linings when handling phosphoric acid or other potent acids.
Insulating fire bricks are generally not resistant to phosphoric acid. Phosphoric acid is a strong acid that can react with and corrode many materials, including fire bricks. While some fire bricks may have a certain level of resistance to acidic environments, it is unlikely that insulating fire bricks would be able to withstand prolonged exposure to phosphoric acid without significant deterioration. It is therefore recommended to use acid-resistant materials, such as acid-resistant bricks or linings, when dealing with phosphoric acid or other strong acids.
Yes, insulating fire bricks are resistant to phosphoric acid.
