POROUS CERAMIC LIQUID-ABSORBING WICK

摘要

PROBLEM TO BE SOLVED: To inexpensively provide a porous ceramic liquid- absorbing wick capable of providing excellent transpiration performance and surely preventing leakage of a chemical by rise of inner pressure of a chemical container and leakage of the chemical by falling of the chemical container, excellent in mass production and e.g. suitably used as a liquid-absorbing wick for sucking type heat-transpiration devices. SOLUTION: The porous ceramic liquid-absorbing wick forms crease-like unevenness 1bb by shrinkage of pipe-like pores 1c on the surface of a porous ceramic formed product 1a mainly composed of silicic ceramic raw material powder.
