Method of Analysis

Determination of ignition gain, particle size distribution, average particle size, specific surface area and combustion properties; gravimetric analysis of zirconium; verification of nitrogen content and accompanying impurities by special analytical methods.

Handling Instructions

Highly flammable solid. Dust explosion hazard. A pure zirconium powder with a high metal content, easily ignitable; rapidly burning off at white heat. Keep away from flames, sparks and heat sources; use ground-connected metallic apparatus to avoid sudden ignition by electrostatic discharge; self-ignition is possible; vacuum- drying of suspensions not recommended; wear gloves, a face shield or goggles; in case of fire, cover only with sand, limestone or with a dry extinguishing powder suitable for metal fires class D; DO NOT USE WATER!
