Ceramic Raschig Ring, is the first development of a random packing.
Simple shape, it is the same height and diameter of the ring.
It is the oldest type of chemical packing as a mass transfer media, is widely used as catalyst support.
Ceramic Raschig Ring, has excellent acid resistance and heat resistance,
can be used in high or low temperature conditions.
It can resist to corrosion of various inorganic acids, organic acids and
organic solvents except hydrofluoric acid.
