Immersion testing molten salts

Due to the wide range of condition for corrosion occurring, there are many tests to evaluate corrosion. These tests include the study of atmospheric corrosion, corrosion during episodic wet/dry conditions, corrosion under fully immersed conditions, corrosion in soil, corrosion in aqueous solutions and corrosion in non-aqueous solutions and in molten salts. Moreover, it is important to consider the in-service environment and the objectives of the tests being performed. 

Sensitivity to initiation (30 mm diam cartridges)-grams of MF to cause complete deton at density (d), 0. 30g at d 0.85, 0.40 at 1.20, 0.50 at 1.40 and 2.5g at d 1.57 g/cc. In these same cartridges, cast R-Salt at d 1.42 reqd a Brisk a detonator for complete detonation (See also Vol 1, p XXIII) Sensitivity to initiation (by heat) - when 0.02g sample in a lOmm test tube was immersed 10 min in a molten metal bath and heated at 5°/min, melt-ing began at 105°, decompn began at 150°, nitrous gases evolved at 160°, and the sample was entirely decompd at 170°. When the tube was plunged into a bath at 300°, decompn was immediate, at 250° decompn was in 40 sec, at 200° in 2 min, at 150° decompn proceeded very slowly, at 110° some bubbles appeared but no increase in decompn occurred in 20 mins (See also Vol 1, pp XXII - XXIII) Specific work - See Coefficient d utilisation pratique...
