PROCEDURE: _________ 4.1 PREPARATION: 4.1.1 Standards: Standards are prepared by grinding 3.1726 grams of titanium oxide (TiO2, SPEX 5-9's) with 0.1575 grams of SPEX MIX #1000 in an agate mortar to produce a 1000ppm standard oxide. Portions of this standard are diluted with TiO2 and ground to produce standard oxides with the concentrations of: 10, 25, 50, 100, 250, 500, & 1000ppm. Fifty mgs of each standard oxide is mixed with 50 mgs of Gallium oxide carrier (1:1 Ga2O3 and High purity graphite) in a wiggle-bug for one minute. Fifty mgs of each mixture is tamped into a crater electrode (001255-12). * For low boron in titanium, standard oxides are prepared as above to give the following concentrations: 5, 10, 25, 50, & 100 ppm. Forty mg of each standard oxide is mixed with twenty-five mg of boron carrier (1:1 BaF and high purity graphite) in a wiggle-bug for one minute. The entire mixture is tamped into a crater electrode (001255-12). ** For tungsten in titanium, standard oxides are prepared as above to give the following concentrations: Blank, 100, 200, 500, & 1000 ppm. Seventy-five mg of each standard oxide is mixed with twenty-five mg Zr carrier (4:2 AgCl and Ga2O3) in a wiggle-bug for one minute. The entire mixture is then tamped into a crater electrode (001255-12). 4.1.2 Samples: Five grams of sample are dissolved in 100 ml of concentrated HCl in a 400 ml PYREX beaker on a medium heat hot plate. If the five gram in 100 ml conc. HCl solution is not available, approximately 1/3 gram of sample may be dissolved with 5 ml of concentrated HCl in a covered TEFLON beaker. Dissolution takes about four hours on a medium hot plate. A two ml aliquot is taken from this solution placed in a platinum dish and dried on a high heat hot plate. The dish is placed in a 500 degree C muffle furnace for two hours. The sample oxide is then removed, cooled, ground and mixed with the appropriate carrier and placed in a crater electrode in the same manner as the standard oxides in 4.1.1.
