1Measured using Hg porosimetry method. 2Average for temperature range of RT - 800°C. 3Measured using 4-point bend method. 4Estimated at 70% of flexural strength. 5Temperature that results in 1% wt. loss in 24 hrs. Oxidation threshold increases by approximately 100°C if graphite is purified. Test sample size equals 0.5” x 0.5” x 1.0".
