Abstract

The invention relates to a metallurgical slag oxygen-ion conduction pool for measuring the conductivity rate of oxygen-ion in metallurgical slag under high temperature. The conduction pool employs Y2O3 to steady ZrO2, on the two sides of the conduction pool being pasted with porous platinum electrode to form the positive and negative electrodes of the conduction pool, in the conduction pool containing slag, two platinum chips being inserted in the slag as electrodes for measuring voltage, on the upper space of the conduction pool being provided with a fixation device for fixing the platinum chips.

Description

1. Technical field: [0001] The invention relates to a metallurgical slag oxygen ion conductivity cell, which is used for measuring the conductivity of oxygen ions in the metallurgical slag at high temperature and belongs to the field of metallurgy. 2. Background technology: [0002] At high temperature, oxides in metallurgical slag mainly exist in the state of cations and anions (mainly oxygen ions), so the conductivity of metallurgical slag is the sum of the conductivity of electrons, cations and anions (oxygen ions). At present, the conductivity cell for measuring the conductivity of metallurgical slag can only measure the total conductivity. The electrode is improved, and the electronic conductivity of the slag can be measured by using an ion-blocking electrode. However, there is no separate conductivity cell for measuring the conductivity of oxygen ions in metallurgical slag. 3. Contents of the invention: [0003] The technical problem solved by the invention is: the...
