Zirconium sponge 

chemical formula: Zr 

Melting point: 1852 ℃ 

Boiling point: 4377 

Density: 6.49 

Particle size: 3-25mm 

Appearance: Zirconium sponge, also known as porous zirconium, is a material with a high surface porosity, a macroscopic network like morphology, and a loose structure. 

Product features: Zirconium metal has very strong corrosion resistance, ultra-high hardness and strength. Zirconium easily absorbs hydrogen, nitrogen, and oxygen; Zirconium has a strong affinity for oxygen, and oxygen dissolved in zirconium at 1000 ℃ can significantly increase its volume. Zirconium is relatively stable in air; Powdered zirconium is prone to combustion. 

Production process: Refined ZrCl4 is reduced by magnesiothermic reduction and vacuum distillation. 

Application areas: 

1) Zirconium sponge is a key material used in nuclear reactors to manufacture cladding for nuclear fuel elements, as well as structural materials for nuclear powered aircraft carriers and reactors. In addition, nuclear grade zirconium sponge is also used as cladding material for nuclear reactors to ensure the safe and efficient operation of nuclear energy facilities. 

2) Aerospace: Zirconium sponge is widely used in the manufacturing of key components such as aircraft engine parts and rocket engine nozzles due to its high strength, high hardness, and good corrosion resistance. These characteristics make it an indispensable material in the aerospace field. 

3) Metallurgical and chemical industry: Zirconium sponge is used to produce acid and alkali resistant equipment, special high-strength and high-temperature alloy materials, vacuum and lighting bulb industry absorbers, etc. It has excellent corrosion resistance and can work stably in harsh chemical environments. 

4) Electronics industry: In the electronics industry, zirconium sponge is used to make key components of electronic devices. Due to its non-magnetic, high-precision, and good conductivity, it ensures the stable operation of electronic devices. 

5) In the military industry, zirconium sponge also has important applications, such as the production of bulletproof alloy steel and special high-strength and high-temperature alloy materials, to enhance the performance of weapons and equipment. 

6) Medical field: Although the search results did not directly mention its applications in the medical field, the corrosion resistance and biocompatibility of zirconium sponge make it potentially valuable for use in medical devices. 

Storage conditions: 

1. Keep dry: The shelf life of zirconium sponge is greatly affected by moisture, and it needs to be stored in a dry environment to prevent moisture absorption. 

2. Avoid direct sunlight: Zirconium sponge materials should be kept away from direct sunlight to prevent changes due to UV reactions. 

3. Reasonable sealing: Before using zirconium sponge, the sealing of the material should be checked first. If it is found that the sealing of the material has been damaged, the material should be replaced in a timely manner. 

4. Pay attention to the storage environment: Zirconium sponge should be stored in a dry, ventilated place and kept away from all harmful gases, odors, and chemicals.
