Method of Analysis

Determination of oxidation value, particle distribution, average particle size, specific surface area and combustion characteristics; gravimetric analysis of zirconium, determination of hydrogen content and impurities. For specific information on Albemarle standard determination methods see our delivery program.

Handling Instructions

Highly flammable solid. Dust explosion hazard. A zirconium powder with maximum metal content, which burns at white heat. Compared with its relative coarse particle size it burns very fast. 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 dry sand, limestone or with a dry extinguishing powder suitable for metal fires class D; DO NOT USE WATER!
