“…Multiple reports on diamond machining using reactions with metals include examples of reactions with molten rare-earth metals and reactions with water vapor catalyzed by Ni deposited films; however, high reaction temperature was a problem. [2][3][4][5] On the other hand, reaction with Li begins around 600 • C, thus promising a new technology.…”

“…This paper presents new calculation results concerning diamond etching with Li considered in the previous paper, 1 and reports on experimental results obtained by applying alkali metal salt solutions to discharge machining. As regards diamond etching through reactions with metals, there are studies on reactions with rare‐earth metals 2 and with water vapor under Ni catalytic action, 3 or at interfaces with KNO 3 catalyst 4 and KOH + KCl catalyst, 5 but the mentioned paper 1 was the first one exploring reactions with alkali metals.…”

“…We examined the temperature using the following procedure: The Nb tube containing the Li-diamond mixture was The etching of a diamond surface has been studied regarding the catalytic oxidation with a Ni film [36], at the melt interfaces with KNO 3 [40] or in an aqueous solution (KCl + KOH) [48] but no reports are found about the reducing conditions. We noted that the etching reaction by Li occurs at a much lower temperature compared to that by oxidation or by dissolution in lanthanoid metals [49].…”

“…Im Vergleich zu Reduktionsprozessen ist Oxidation bei niedrigeren Temperaturen möglich [111]. Oxidation von Diamant wurden für verschiedenen Ätzverfahren beobachtet, darunter Gasphasenätzen mit Sauerstoff, Wasserstoff und Wasserdampf, Plasmaätzen mit Sauerstoff und Nassätzen [112][113][114][115][116], wobei Nassätzen mit flüssigem KNO 3 bei Temperaturen oberhalb von 798 K eine gängige Methode zum Ätzen von Diamant ist [111].…”

“…Yao et al [116] haben Ätzversuche an Diamant {100} Flächen mit flüssigem KCL + KOH für 5 Stunden bei 1373 K durchgeführt und die Rate der Materialabtragung an der Oberfläche bestimmt. Die Probendicke war nach dem Ätzen um 10 % verringert, woraus eine Ätzrate von 2 ➭m h −1 für die {100} Flächen errechnet wurde.…”
