The price of aluminum silicate ceramic fiber special-shaped parts is higher mainly for the following reasons:

1. High cost of raw materials: aluminum silicate ceramic fiber is a high-performance ceramic material, its preparation requires the use of high-purity raw materials, and through multi-process processing, high cost of raw materials.

2. Complex manufacturing process: The manufacturing process of aluminum silicate ceramic fiber shaped parts needs to go through multiple processes, including fiber preparation, molding, sintering and other links need to strictly control the process parameters and quality requirements, the process complexity is high, and the manufacturing cost is relatively high.

3. High performance and special requirements: aluminum silicate ceramic fiber special-shaped parts are usually used in high temperature, corrosion and other special environments, requiring excellent heat resistance, corrosion resistance, insulation and other properties, which requires special optimization in material selection and manufacturing process, increasing the cost and manufacturing difficulty.

4. The market demand is relatively small: aluminum silicate ceramic fiber shaped parts are mainly used in some special industries, such as aerospace, metallurgy, chemical industry, etc., the market demand is relatively small, the production scale is relatively small, but also led to the relatively high product prices.
