Production Details
Xintai Refractory’s Standard Size Acid Resistant Bricks are manufactured using superior-grade fireclay, silica, and other acid-resistant raw materials. These bricks are formed through high-pressure molding and fired at high temperatures in a tunnel kiln to ensure excellent density, mechanical strength, and chemical stability.
Our production process follows strict quality control protocols at every stage—from raw material selection and grinding to shaping, drying, and final firing. This ensures uniform size, low porosity, and consistent performance even under harsh chemical environments. The standard size is typically 230×114×65mm, though customized dimensions are also available upon request to suit various lining requirements.

Frequently Asked Questions (FAQ)
Q1: What are acid resistant bricks used for?
Acid resistant bricks are primarily used for lining chemical plants, chimneys, tanks, reactors, flooring in chemical processing areas, and other structures exposed to acidic environments. They provide excellent protection against corrosion from acids and other aggressive chemicals.
Q2: What is the standard size of acid resistant bricks?
The most common standard size is 230mm x 114mm x 65mm. However, other sizes such as 200 x 100 x 38mm or 300 x 150 x 75mm can also be customized based on specific requirements.
Q3. What materials are used in acid resistant bricks?
These bricks are generally made from high-quality raw materials like fire clay, feldspar, and quartz. The material composition ensures low water absorption and high resistance to acids and alkalis.
Q4: What types of acids can these bricks resist?
Xintai Refractory’s acid resistant bricks are effective against a wide range of acids, including sulfuric acid, nitric acid, hydrochloric acid, and organic acids (except hydrofluoric acid and strong alkalis).
Q5: Do you offer custom sizes or shapes?
Yes. As a professional manufacturer, Xintai Refractory can provide custom sizes, shapes, and even pre-engineered lining systems to meet your specific design needs.
