Aluminum Silicate Fiberboard

Brief Introduction of Aluminum silicate fiberboard

 

Aluminum silicate fiberboard, also known as ceramic fiberboard, is a board with good fire resistance, high compressive strength and long service life; small heat capacity and low thermal conductivity; non-brittle material with good toughness; precise size and good flatness; easy to cut and install, convenient construction; excellent wind erosion resistance; continuous production, uniform fiber distribution, stable performance; and excellent sound absorption and noise reduction performance.

 

Chemical composition of Aluminum silicate fiberboard

 

Element	content
SiO2	48~52%
Al2O3	43~49%
Fe2O3	0.9~0.13%
CaO	＜1%
MgO	Trace

 

These ingredients give aluminum silicate fiberboard the advantages of high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity, good resistance to mechanical vibration, small thermal expansion, and good thermal insulation performance.

 

Ceramic Fiberboard vs Aluminum Silicate Fiberboard

 

Ingredients and Manufacturing Process

 

Ingredients: The main component of ceramic fiberboard is aluminum silicate, a compound composed of siloxane and aluminoxane.
Manufacturing Process: Aluminum silicate fibers (i.e. ceramic fibers) are made by melting hard clay clinker at high temperatures and then blowing or spinning them into fibers. These fibers can then be used to make ceramic fiberboard.

 

Origin of the name

 

Ceramic fiberboard: Since its main component is ceramic fiber, it is called ceramic fiberboard.
Aluminum silicate fiberboard: Since its main chemical component is aluminum silicate, it can also be called aluminum silicate fiberboard.
