Ceramic Honeycombs
With high achievable surface per unit volume and low thermal expansion,ceramic honeycombs are utilized in catalyst carriers, active catalysist and air flow distributors, also used for heat exchanger processes, electro-chemical applications and carrier bodies for biologial applications and still utilized in catalytic converters for purifying vehicle exhaust gas ,reducing carbon monoxide ,smog etc.
