Zirconium plate

"Zirconium plate" refers to a plate made of zirconium (Zr). Zirconium is a silver-white transition metal that belongs to Group IVB in the periodic table of elements. It has important applications in many industrial fields due to its excellent properties.

Zirconium plate details

Zirconium plates, zirconium sheets

Zirconium and zirconium alloys have a series of characteristics such as low density, high specific strength, corrosion resistance, radiation resistance, excellent wear resistance, excellent processing performance, non-toxic, non-magnetic, and small thermal neutron absorption cross-section.
In view of the fact that zirconium and zirconium alloys have the characteristics of low density, high specific strength, corrosion resistance, radiation resistance, excellent wear resistance, excellent processing performance, non-toxic, non-magnetic, etc., they are different from traditional stainless steel, copper, nickel, titanium and other metal alloys. , zirconium and zirconium alloys have excellent corrosion resistance and can withstand corrosion from most organic acids, inorganic acids, strong alkali and some molten salts. In the wastewater treatment, food processing, and strong acid production industries, it is mainly used in equipment and components with high corrosion resistance requirements, such as reactors, acid-resistant pumps, heat pumps, heat exchange pipes, soaking tanks, acid-resistant impellers, valves, etc., agitators, Spout and container lining.

Physical properties:
High melting point, about 1852°C.
Density is approximately 6.5 g/cm³.
Good corrosion resistance because zirconium can quickly form a stable oxide film in the air.
Low thermal conductivity.
Good mechanical properties, including strength and hardness at high temperatures.
Chemical Properties:

Excellent corrosion resistance to most acids and alkalis.
At normal temperatures, zirconium is resistant to a variety of corrosive environments, including seawater and many acidic solutions.
Unlike some metals, zirconium does not burn in air but forms an oxide film.

The main purpose:
Nuclear industry: Used as cladding material for nuclear fuel rods and structural components of reactors because of its small absorption cross-section for neutrons.
Chemical Equipment: Used to make heat exchangers, reactors, etc., especially when handling corrosive chemicals.
Aerospace: Used in jet engine components and spacecraft structures for its ability to maintain stability at high temperatures.
Medical devices: Biocompatible zirconium alloys can be used to make surgical implants such as artificial joints.
Marine engineering: Because of its ability to resist seawater corrosion, it can be used in ship parts and marine exploration equipment.
Metallurgical industry: used as corrosion-resistant crucible materials or containers when smelting precious metals.
