This completes my set of titanium, zirconium, and hafnium crystal bars (a complete column). All three of these metals are, or used to be, refined using a similar iodic decomposition process, so all can be found in roughly this crystal form. Although I have many favorite samples, the combination of these three crystal bar samples is without doubt my favorite column in the table.
I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
