AUTO and Motor Catalyst Support

CO,HC,and NOx go through purifier made of multi-hole cordierite catalyst honeycomb carrier, it make the gases more active and do oxide-reducing chemical reaction. CO is oxidized into no color and no poison CO2 under high temperature. HC chemical compound is oxidized into H2O and CO2. NOx is restored into nitrogen gas. The poisonous gases are made into unpoisonous gas to make them pure.

10) Structural Integrity to Thermal Shock

(Cooling with water)
Cracks start at approx. 800C 
No destruction of ceramic bodies until approx. 1180C

11) Softening temperature

Definition: temperature, at which the instantaneous rate of thermal expansion is zero.
Procedure: analogous to coefficient of thermal expansion; determination with extrapolation.

Minimum: 1380C
