Abstract

L'invention décrit des charges ignifuges améliorées destinées à des matériaux plastiques, qui sont constituées par des particules d'hydroxyde de magnésium à surface moyenne réduite. On produit ces particules en mettant en contact des particules d'hydroxyde de magnésium de surface moyenne relativement élevée, avec une solution d'attaque pendant une durée suffisante pour dissoudre au moins quelques unes des particules et laisser les particules à surface moyenne réduite.
