Oxygen Behaviour In The Process Of Float Glass Manufacturing

By means of solid electrolyte probes the oxygen content was determined in inert gas atmosphere and in the tin melt. The probes can be used within a temperature range of 500 deg C for tin melt and 600 deg C for inert gas atmosphere up to 1100 deg C. A higher emf value causes an oxygen decrease, a lower emf value leads to an oxygen increase in the system. From the measured emf values, the oxygen partial pressures in the inert gas atmosphere and the oxygen contents in the tin melt can be calculated by means of the respective mathematical relations.
