Zirconium Powder Description
Micro Zirconium Powder consists of finely divided zirconium particles, typically ranging from a few to several tens of micrometers in size. This powder is known for its high melting point, excellent corrosion resistance, and strong affinity for oxygen, which makes it an effective getter material in vacuum systems. Additionally, Micro Zirconium Powder exhibits excellent mechanical strength and stability at high temperatures, making it suitable for use in extreme environments.
The powder's unique properties include its low neutron absorption cross-section, which is particularly valuable in nuclear applications. It is also highly reactive, especially in finely divided form, and can be used in pyrotechnics and as a fuel in solid rocket propellants. Furthermore, Micro Zirconium Powder has excellent thermal and electrical conductivity, making it useful in electronics and advanced material applications. Overall, the combination of chemical reactivity, high-temperature stability, and resistance to corrosion makes Micro Zirconium Powder a versatile material for a wide range of industrial applications.
