| abstract |
The present invention relates to a process for producing inorganic porous materials, mainly composed of glass or glass-ceramic components. The glass or glass-ceramic components can have interconnected continuous macropores with a median diameter larger than 0.1 μm, and mesopores in the walls of said macropores, said mesopores having a median diameter between 2 and 100 nm. The process can include dissolving a water-soluble polymer or some other pore forming agent and a precursor for a matrix dissolving agent in a medium for mixing with a metalorganic compound. |
