Usage

Chemical Properties

Crystals or powder. Soluble in water.

Uses

Intermediate for boron chemicals; as a powerlevel control in atomic submarines.

Air & Water Reactions

Water soluble.

Reactivity Profile

Salts, basic, such as AMMONIUM PENTABORATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

Health Hazard

Inhalation of dust may result in non-specific irritation of upper respiratory tract. Ingestion of large quantities may produce symptoms of non-specific irritation of the gastrointestinal tract, nausea, vomiting, cramps, diarrhea. Contact with dust causes moderate eye irritation and minor skin irritation.

Fire Hazard

Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fire.

Flammability and Explosibility

Nonflammable
