Combustion Boat Ceramic

Combustion Boats are used in the estimation of carbon in steel samples. The sample of steel drilling is taken in a combustion boat and placed inside a tube furnace maintained at 1300 deg to 1400 deg & oxygen is passed over it which combines with carbon of the steel & CO2 is estimated. Propirties of combustion Boats are High thermal shock resistance, High softening temperature & high resistance to corrosive action to molten steel. Combustion boats are made either by slip casting in plaster of paris moulds or by mechanical pressing.
