Types of Aluminum Silicate Fiber Products
Aluminum silicate fibers are primarily composed of alumina and silica that are melted together, with alumina making up a significant portion. Since alumina is a major component of ceramics, these fibers are also referred to as ceramic fibers. These products are manufactured through processes such as blowing and spinning. See the main types of ceramic fiber products.
