Lithium in bentonites
WebThe evidence of α-cristobalite in bentonites is hazardous for the human health and reduces their marketing. To distinguish the opal-C and opal-CT from α-cristobalite, the XRD-patterns of bentonites before and after H 3 PO 4 -digestion (240 °C, 15 min) and heat treatment (1050 °C, 24 h) were evaluated in details.

Web5 apr. 2024 · Lithium metal is produced by electrolysis of a fused mixture of lithium and potassium chlorides. The lower melting point of the mixture (400–420 °C, or 750–790 °F) compared with that of pure lithium chloride (610 °C, or 1,130 °F) permits lower-temperature operation of the electrolysis.
