Lithium borohydride crystallizes
Web1 jul. 2024 · Properties of hydride sources. Two practical sources of hydride-like reactivity are the complex metal hydrides lithium aluminium hydride (LiAlH 4) and sodium borohydride (NaBH 4).These are both white (or near white) solids, which are prepared from lithium or sodium hydrides by reaction with aluminum or boron halides and esters. http://www.axiomchemicals.in/lithium-borohydride-supplier.htm
