[0032] Embodiment 1-21: Preparation of gallium ink
[0033] Gallium inks were prepared according to the materials and amounts shown in Table 1. Specifically, for each of the examples shown in Table 1, gallium metal was weighed and added to the reactor equipped with a stirrer. The liquid carrier was then added to the reactor followed by any other solid materials listed in Table 1 (ie, pyrazines). The reactor was then assembled in a glove box and the reactor was sealed under nitrogen. The reactor was then transferred to a fume hood and a positive nitrogen pressure was maintained in the reactor with a nitrogen manifold. The remaining liquid material was then added through the septum on the reactor using an inert syringe. Then, under the reaction conditions shown in Table 1, the materials in the reaction vessel were processed. With cooling, the reactor was transferred to a glove box for unloading of materials. The product ink was then decanted from the reactor to remove any ...

[0042] Example 22-25 gallium ink analysis
[0043] The decanted product gallium inks from Examples 10, 12, and 14-15 were placed in separate round bottom flasks under a nitrogen atmosphere. Volatile materials were removed from product samples under reduced pressure. For Example 22, volatiles were removed by first rotary evaporation at 2.67 kPa and a temperature of 80-85°C. For Examples 23-25, volatiles were removed by first performing a short path distillation at 0.13 kPa and a temperature of 80-85°C. All samples were then placed under a house vacuum of 2.67 kPa for two days to remove any remaining volatiles. The remaining sample material in the round bottom flask was analyzed by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). The results of these analyzes are listed in Table 2.
