    摘要: A method for producing a high porosity ceramic material characterized by the steps of: (1) wetting a finely divided, non-crystalline, amorphous silica with a wetting agent; (2) combining the wetted silica with a ceramic slip to produce a mixture; and (3) removing the majority of the wetting agent to produce a solid, low-density, highly porous bisque. The bisque if preferably partially covered with an impermeable coating, and an aromatic fluid is applied to an exposed surface of the bisque for absorption into the body of the bisque.
