You can prepare/regenerate some excellent desiccating agents - calcium oxide (600 °C), magnesium oxide (800 °C), and barium oxide (800-1000 °C).
You can prepare potassium cyanide by the Wagner process (650 °C):
K4[Fe(CN)6] + K2CO3 + C => 6KCN + Fe + CO2 + CO
You melt a whole bunch of elements (up to iron, maybe even titanium) and thus can prepare mixtures of same (alloys, etc.) or cast them into
useful shapes. |
