1. Scientific research and experimental fields:• Material synthesis and analysis: In laboratories of universities and scientific research institutions, niobium crucibles are often used in synthesis experiments of various materials, such as the synthesis of new ceramic materials, intermetallic compou

1. Aerospace:• Manufacture of engine parts, such as structural materials of aircraft engines, rocket nozzles, combustion chambers, combustion ducts, turbo pumps, etc. Because niobium has a high melting point, good oxidation resistance and strength, it can maintain stable performance in extreme envir

Uses of niobium plates:• Superconductivity: Niobium will show superconductivity at low temperatures, so niobium plates can be used to make superconducting magnets. For example, in magnetic resonance imaging (MRI) equipment, superconducting magnets can generate stable and strong magnetic fields. Niob

Tantalum has the characteristics of high melting point and good chemical stability. In the smelting process of sapphire (the main component is alumina), it can withstand high temperature environment and has a low possibility of contaminating sapphire raw materials, which can ensure a relatively pure

1. ScarcityHafnium has relatively small reserves in nature. It usually coexists with zirconium and is difficult to separate and extract, which limits its production and prevents it from being mass-produced like some common metals. Scarcity directly leads to higher prices.2. Special uses1. Nuclear in

1. Aerospace field: Engine components: Niobium hafnium alloy has excellent high temperature strength, creep resistance and oxidation resistance, can be used to manufacture aircraft engine turbine blade, combustion chamber, afterburner and other key components. These components need to withstand the
