Can a high alumina brick resist sulphuric acid?

　　High alumina bricks generally have good resistance to acid corrosion, including resistance to sulfuric acid. The high alumina content in these bricks provides them with excellent chemical resistance against acidic environments, including sulfuric acid.

　　Sulfuric acid is a strong mineral acid commonly used in various industrial processes. High alumina bricks typically have an alumina (aluminum oxide) content of 50% or higher, which imparts exceptional resistance to acidic conditions. The dense and non-reactive nature of alumina helps protect the brick from the corrosive effects of sulfuric acid.

　　However, it's important to note that the resistance of high alumina bricks to sulfuric acid can depend on factors such as concentration, temperature, and contact time. Extremely concentrated or hot sulfuric acid may still have some corrosive effect on the bricks over extended periods.

　　For applications where sulfuric acid exposure is expected, it is advisable to consult with refractory experts or manufacturers who can provide specific recommendations based on the concentration, temperature, and duration of exposure to ensure the selection of the most suitable brick composition.
