摘要

The present invention provides fire resistant compositions comprising an iron containing composition having fire retardant properties selected from the group consisting of iron (II) carbonate, iron carbonate hydroxide, iron (II) hydroxide, iron (III) hydroxide and a combination thereof and a method to manufacture the iron containing composition from a metal chloride stream. The iron containing composition can also be used as a sound suppressant or an electrical insulator.
