Das Haupteinsatzgebiet ist die Kerntechnik, in der Hafnium als <a href="/wiki/Steuerstab" title="Steuerstab">Steuerstab</a> zur Regulierung der <a href="/wiki/Kettenreaktion_(Kernphysik)" class="mw-redirect" title="Kettenreaktion (Kernphysik)">Kettenreaktion</a> in <a href="/wiki/Kernreaktor" title="Kernreaktor">Kernreaktoren</a> eingesetzt wird. Die Verwendung von Hafnium hat gegenüber anderen möglichen neutronenabsorbierenden Substanzen einige Vorteile. So ist das Element sehr korrosionsbeständig und bei der Kernreaktion mit den Neutronen entstehen Hafniumisotope, die ebenfalls hohe <a href="/wiki/Absorptionsquerschnitt" class="mw-redirect" title="Absorptionsquerschnitt">Absorptionsquerschnitte</a> besitzen.<sup id="cite_ref-28" class="reference"><a href="#cite_note-28"><span class="cite-bracket">[</span>28<span class="cite-bracket">]</span></a></sup> Auf Grund des hohen Preises kommt es häufig nur für militärische Anwendungen in Frage, beispielsweise für Reaktoren in <a href="/wiki/Atom-U-Boot" title="Atom-U-Boot">Atom-U-Booten</a>. </p><p>Es existieren noch einige weitere Verwendungsmöglichkeiten. So reagiert Hafnium schnell mit geringen Mengen Sauerstoff und Stickstoff und kann darum als <a href="/wiki/Getter" title="Getter">Gettersubstanz</a> eingesetzt werden, um kleinste Mengen dieser Stoffe aus <a href="/wiki/Vakuum" title="Vakuum">Ultrahochvakuum</a>-Anlagen zu entfernen. Beim <a href="/wiki/Verbrennung_(Chemie)" title="Verbrennung (Chemie)">Verbrennen</a> sendet das Metall ein sehr helles Licht aus. Deshalb ist es möglich, Hafnium in <a href="/wiki/Blitzlicht" title="Blitzlicht">Blitzlichtlampen</a> mit einer besonders hohen Lichtausbeute einzusetzen. Darüber hinaus kann es zur Herstellung sehr stabiler und hochschmelzender Verbindungen verwendet werden, insbesondere <a href="/wiki/Hafniumnitrid" title="Hafniumnitrid">Hafniumnitrid</a> und <a href="/wiki/Hafniumcarbid" title="Hafniumcarbid">Hafniumcarbid</a>. </p><p>In Legierungen mit Metallen wie <a href="/wiki/Niob" title="Niob">Niob</a>, <a href="/wiki/Tantal" title="Tantal">Tantal</a>, <a href="/wiki/Molybd%C3%A4n" title="Molybdän">Molybdän</a> und <a href="/wiki/Wolfram" title="Wolfram">Wolfram</a> wirkt ein Zusatz von 2 % Hafnium festigkeitssteigernd. Es entstehen besonders stabile, hochschmelzende und hitzebeständige Werkstoffe. </p><p>Aus Hafnium wurde eine einzige Gedenkmünze geprägt: 2002 eine 5 Kronen-Münze der <a href="/wiki/Turks-_und_Caicosinseln" title="Turks- und Caicosinseln">Turks- und Caicosinseln</a>.<sup id="cite_ref-29" class="reference"><a href="#cite_note-29"><span class="cite-bracket">[</span>29<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Sicherheitshinweise">Sicherheitshinweise</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hafnium&veaction=edit&section=9" title="Abschnitt bearbeiten: Sicherheitshinweise" class="mw-editsection-visualeditor"><span>Bearbeiten</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Hafnium&action=edit&section=9" title="Quellcode des Abschnitts bearbeiten: Sicherheitshinweise"><span>Quelltext bearbeiten</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Wie viele andere Metalle ist Hafnium in feinverteiltem Zustand <a href="/wiki/Leichtentz%C3%BCndlich" class="mw-redirect" title="Leichtentzündlich">leichtentzündlich</a> und <a href="/wiki/Pyrophor" title="Pyrophor">pyrophor</a>.
