General description

Anhydride can be obtained by heating boric acid at temperatures higher than 160oC.1

Application

Reducing boron anhydride in the presence of sodium yields amorphous boron. Whereas reducing in the presence of aluminum at high temperatures affords crystalline boron. 1

CaO-SiO(2)-P(2)O(5)-B(2)O(3) glass ceramics directly bond to bone and have potential use as a bone substitute material. The present study evaluated the toxicity from subchronic intravenous administration of CaO-SiO(2)-P(2)O(5)-B(2)O(3) glass ceramics to male and female Sprague-Dawley rats. The rats were divided
