The Van Arkel-de Boer Process is used to produce ultrapure and ductile Titanium, Zirconium, Hafnium, Vanadium, Thorium, or Protactinium.
It is also known as the Iodide Process or Crystal Bar Process.
Products
Main Product: Ultrapure Ti, Zr, Hf, V, Th, or Pa
Side Product(s): None
Steps
1 Metal Dust (s) + 4 Iodine Dust (s) -> 5 Metal Tetraiodide Dust (s)
For Example: Ti (s) + 4I (s) -> TiI4 (s)
This is done at around 698K for Titanium.
5 Metal Tetraiodide Dust (s) -> 1000L Metal Tetraiodide Gas (g)
For Example: TiI4 (s) -> TiI4 (g)
The solid metal iodides are then boiled into gaseous forms at low pressures.
1000L Metal Tetraiodide Gas (g) -> 1 Ultrapure Metal Dust (s) + 4 Iodine Dust (s)
For Example: TiI4 (g) -> Ti (s) + 4I (s)
They are then decomposed with a 1673K tungsten filament. As they decompose, metal is deposited onto the filament, which increases conductivity. This means more energy is required to maintain the same temperature as the recipe goes on.
This behavior could be a new automation mechanic/challenge. As recipe progress increases, so would the required voltage.
Yield
1 Metal Dust -> 1 Ultrapure Metal Dust (ratios are easily adjustable).
