Abstract
Lower phosphates, such as phosphites and hypo-phosphites, are known to have a characteristic of particularly strong reducibility. We researched on phosphite compounds and found out that aluminum phosphite had an excellent property. Aluminum phosphite, the product name of ‘APA-100’, was investigated in this study. Since APA-100 has a characteristic of hardened foam material by heating, this material is effective as a flame retardant. As a result of corrosion-resistant evaluation using the copper foil, the control of the corrosion by the effect of APA-100 was found out. Furthermore, we succeeded in the development of the fine particle type of APA-100. The details on aluminum phosphite (APA-100) for various uses were reported.
