Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines kristallinen Metallborids, bei dem ein Reaktionsgemisch hergestellt oder bereitgestellt wird, wobei wenigstens eine erste Komponente des Reaktionsgemisches das Metall (Me) enthält oder das elementare Metall ist und wenigstens eine zweite Komponente des Reaktionsgemisches Bor (B) enthält oder elementares Bor ist und wenigstens eine dritte Komponente des Reaktionsgemisches ein Hilfskomponente, insbesondere zum Lösen der wenigstens einen ersten Komponente und der wenigstens einen zweiten Komponente einerseits und zur Reduzierung des Sättigungsdampfdrucks der einzelnen Komponenten des Reaktionsgemisches andererseits, ist, bei dem das Reaktionsgemisch auf wenigstens eine vorgegebene oder vorgebbare Prozesstemperatur erwärmt wird, wobei das Reaktionsgemisch in eine Reaktionsschmelze überführt wird, und bei dem während einer vorgegebenen oder vorgebbaren Prozessdauer aus der Reaktionsschmelze als Produkt wenigstens ein Metallborid(Mg¶x¶B¶y¶)-Kristall mit einem stöchiometrischen B : Me-Verhältnis x¶B¶ : x¶Me¶ von wenigstens 11 : 1 erzeugt wird. Die Erfindung betrifft weiterhin ein kristallines Metallborid, insbesondere hergestellt nach dem Verfahren.
