Celmet is the porous metal whose frame has three-dimensional network structure like sponge.
Celmet has much larger porosity compared to sintered metals produced by metal powder or metal fiber.
"Because of this unique feature, Celmet is adopted widely in a variety of industrial fields.
For example, electrodes of Ni-Mh battery, oil mist separators, and carriers of industrial deodorizer catalyst."
