Zirconia Containing Aluminum Silicate Fiber Board

Zirconia Containing Aluminum Silicate Fiber Board is manufactured using a wet vacuum filtration and pressure molding process, with loose cotton fibers as the base material and added organic and inorganic binders. The product is hard, high-strength, erosion-resistant, and easy to process.  The refractory fiber raw materials have stable chemical properties and offer the advantages of being lightweight and providing thermal insulation. It can be directly used on the hot face of furnace linings to withstand flames and high-temperature gas flow.

一.Physical And Chemical Indicators of Zirconia Containing Aluminum Silicate Fiber Board

二.Zirconia-containing ceramic fiber board is an inorganic non-metallic material with zirconia (ZrO₂) as the reinforcing phase. Its density is a key parameter for measuring the mass per unit volume. According to the international standard ISO 10635, the typical density range is 1.8-2.5 g/cm³, with the specific value affected by the following factors:

1. Zirconia content: The higher the proportion of zirconia, the greater the density. For example, a fiberboard with 10% zirconia has a density of approximately 2.1 g/cm³, while one with 15% zirconia can reach 2.4 g/cm³.

2. Porosity: The porous structure inside the fiberboard reduces the density; for example, a porosity of 30% can reduce the density to below 1.9 g/cm³.

3. Molding process: Dry pressing results in a product density approximately 0.2 g/cm³ higher than wet molding (Reference: "Handbook of Advanced Ceramic Materials").
