A method of measuring the concentration of a molten bath component comprises the steps of placing a test sample in contact with the molten bath sample, measuring a change in temperature of that sample due to dissolution of the test sample, and determining the concentration of the component in that molten bath based on the change in sample temperature. The test sample can comprise alumina, and the molten bath can comprise a cryolite bath. The test sample can be placed in a probe chamber, which is then immersed in the molten bath, opened to permit the sample of the molten bath to enter the probe chamber, and closed prior to the step of measuring a change in temperature of the sample of the molten bath. An apparatus for measuring the concentration of the component in a molten bath is also disclosed.
A method of measuring a concentration of a component in a molten bath comprising the steps of:
The method of clam 1, wherein the test sample comprises alumina, and wherein the molten bath comprises a cryolite bath.
The method of clam 1, wherein the step of placing a test sample in contact with the sample of the molten bath comprises the steps of:
The method of clam 1, wherein the step of measuring a change in temperature of the sample of the molten bath due to dissolution of the test sample comprises the steps of:
The method of clam 4, wherein the step of measuring the difference in temperature between the sample of molten bath and a reference sample of the molten bath comprises the steps of:
The method of clam 1, wherein the step of measuring a change in temperature of the sample of the molten bath due to dissolution of the test sample comprises the step of measuring a difference in temperature between the temperature of the first sample of the molten bath and the temperature of a second sample of the molten bath;
The method of clam 1, wherein the step of measuring a change in temperature of the sample of the molten bath due to dissolution of the test sample comprises the step of measuring a difference in temperature between the temperature of the first sample of the molten bath and the temperature of a second sample of the cryolite bath;
An apparatus for measuring a concentration of a component in a molten bath comprising:
