Boric trioxide

WebBoron FRs accelerate the reactions of dehydration [250], decarboxylation and charring during pyrolysis [251]. The boric acid is seen to undergo endothermic water-losing reactions. These latter occur in two steps to produce metaboric acid (HBO 2) and water-free boron trioxide (B 2 O 3), respectively [249, 252].
