Abstract:It is important to elect a suitable measurement method and an apparatus of pore structure parameters for fiber porous ceramics, whose filter performances depend on it's pore structure. A test apparatus based on the principle of liquid displacement porometry is established for determining pore structure parameters of fiber porous ceramics. The measuring principle and method of pore structure parameters are discussed in the article. BP neural networks are adopted to treat measured data in the computer programs. The results provide direct reference for optimization of preparation process.

Keywords:fiber porous ceramics, pore structure parameters, measurement apparatus, liquid displacement method, BP neural networks
