Micro Metallic'' filters with pore sizes of 5, 20, 35, and 65 microns were tested for their effectiveness in removing carbon from sodium. Carbon was added to sodium, held at 1200 deg F for solution of carbon, and subsequently filtered at either 1200 or 300 deg F. Vacuum filtering was necessary to effect the flow of sodium through the filters. The carbon content of sodium filtered at 1200 deg F was below the reported solubility of carbon in sodium containing 40ppm oxygen at the solution temperature. The carbon content of sodium filtered at 300 deg F was approximately the same as the reported solubility of carbon in sodium containing 40ppm oxygen at the precipitation temperature. The 5, 20, and 35 micron filters appeared to be equivalent in ability to remove carbon at 300 deg F. The 65 micron filter was relatively ineffective. Although the tests were not sufficiently controlled to establish quantitative evaluation of filtering for carbon removal, the results indicate the feasibility of the method. (auth)
