Acid-Resistant Ceramic Bricks and Tiles for Corrosion Protection

Acid-resistant ceramic bricks and tiles line surfaces that would otherwise be eaten away by acids and other corrosive chemicals. They go down as flooring, wall cladding and lining in chemical plants, electroplating and pickling shops, fertiliser and dye works, storage tanks, trenches and reaction vessels, where spills, fumes and immersion attack ordinary concrete or steel. Fired dense and almost non-absorbent, they hold up to strong acids for years and protect the structure beneath.

Very — their acid resistance is above 99 percent, so almost nothing is lost when the ceramic meets strong acid. They resist most acids across a range of concentrations, along with many salts and solvents, which is why they are the standard lining for acid-handling floors and tanks. They are strongest against acids in particular; for heavy alkaline or hydrofluoric service the material should be confirmed for the specific chemical.

We supply both thicker bricks and thinner tiles, or porcelain plates, in a range of standard sizes, and we make custom sizes to order. Bricks run to around 230 by 113 by 65 millimetres for heavy-duty flooring and lining, while the plates come in sizes such as 150 by 150 and 300 by 300 millimetres in thinner sections for cladding. Tell us the surface and the duty and we will advise the size and thickness.

They are bedded and jointed with an acid-resistant mortar or resin, laid over a prepared and often membrane-protected base, so that both the ceramic and the joints resist the chemical. The bricks take the wear and the chemical attack while the mortar seals the gaps and the membrane backs them up, giving a lining that keeps acid off the structure. Correct bedding and jointing matter as much as the brick itself.

It is mostly thickness and use. Acid-resistant bricks are thicker and stronger, made for floors, trenches and heavy lining that must carry load and take impact as well as resist chemicals. Acid-resistant tiles or porcelain plates are thinner, for wall cladding and lighter-duty surfaces. Both are the same acid-resistant ceramic; the form is chosen for where it goes.
