Aluminum silicon series refractory bricks

Aluminum silicon refractory brick, also known as aluminum silicon refractory brick, is a series of refractory materials containing Al2O3 and SiO2. Aluminum silicon refractory bricks have a wide range of applications and occupy a very important position in the refractory material application industry, accounting for more than 40% of the total refractory material products.
From a definition perspective, aluminum silicon refractory bricks are a series that includes multiple types of refractory bricks. Aluminum silicon refractory bricks are classified in order of increasing composition from SiO2 content to Al2O3 content: (1) Silicon bricks: SiO2 content ≥ 93%; (2) Half silica brick: Al2O3 content of 15% -30%; (3) Clay brick: Al2O3 content is 30% -48%; (4) High alumina brick: Al2O3 content ≥ 48%; (5) Molestone bricks: Al2O3 content ≥ 72%, SiO2 content ≥ 28%; (6) Corundum brick: Al2O3 content ≥ 90%. From the classification, it can be seen that silica bricks, clay bricks, and high alumina bricks are commonly used refractory bricks in kilns, often used for laying kiln working layers, permanent layers, etc.
