Das silbergraue Metall der seltenen Erden ist sehr weich, gut dehnbar und schmiedbar.
In trockener Luft ist Thulium recht beständig, in feuchter Luft läuft es grau an. Bei höheren Temperaturen verbrennt es zum Sesquioxid.Mit Wasser reagiert es unter Wasserstoffentwicklung zum Hydroxid. In Mineralsäuren löst es sich unter Bildung von Wasserstoff auf.
In seinen Verbindungen liegt es in der Oxidationsstufe +3 vor, die Tm3+-Kationen bilden in Wasser pastell-bläulich-grüne Lösungen.

Verwendung

Verwendung in Fernsehgeräten (zur Aktivierung der Leuchtstoffe auf der Bildschirmfläche) gibt es nur wenige kommerzielle Anwendungen:
Aus Nuklearreaktoren ausgelagertes 170Tm dient als Röntgenstrahlungsquelle (Gammastrahler in der Materialprüfung)
Thuliumdotiertes Yttriumtantalat oder Lanthanoxybromid (LaOBr) dient als Szintillator in Röntgenverstärkerfolien oder Leuchtschirmen in der Röntgentechnik
Thuliumdotiertes Calciumsulfat dient als Detektor in Personendosimetern zur Messung niedriger Strahlendosen
Thuliumkristalle können als aktives Medium in diodengepumpten Festkörperlasern (Wellenlänge 2 µm) mit einem Gesamtwirkungsgrad von bis zu 10 % bei maximal 60 W Lichtleistung verwendet werden.
Thuliumdotiertes Kieselglas als aktives Medium in Faserlasern (Wellenlänge 2 µm) wurde mit einem differentiellen Wirkungsgrad von 53,2 % bei einer Leistung > 1000 W betrieben.
Thulium und Thuliumverbindungen sind gering toxisch. Thuliumstäube sind feuer- und explosionsgefährlich.

Gewinnung

Nach einer aufwändigen Abtrennung der anderen Thuliumbegleiter wird das Oxid mit Lanthan zum metallischen Thulium reduziert. Anschließend wird das Thulium absublimiert
