Overview of Niobium 99.95% Pure Niobium Bar / Ingot / Metal / Block / Rods Per Kg
Niobium, often found in conjunction with tantalum minerals, is primarily extracted as a byproduct of tin and tantalum mining. Its chief ores include pyrochlore and columbite. Once refined, niobium becomes highly versatile, finding application in alloys, superconductors, and various high-tech materials.
Feature of Niobium 99.95% Pure Niobium Bar / Ingot / Metal / Block / Rods Per Kg
-
Superior Strength and Lightness: When added to steel in small quantities (typically less than 1%), niobium significantly enhances the strength and toughness of the alloy while reducing its weight, making it ideal for aerospace and automotive applications.
-
Corrosion Resistance: Like tantalum, niobium forms a passive oxide layer that protects it from corrosion, making niobium-based alloys suitable for use in harsh environments.
-
Superconductivity: Niobium exhibits excellent superconducting properties when cooled below its critical temperature of about 9.2 K (-264°C or -443°F). This property makes it the primary material for superconducting magnets used in MRI scanners and particle accelerators.
-
Magnetic Properties: Niobium is paramagnetic at room temperature but becomes strongly diamagnetic when cooled, meaning it repels magnetic fields. This characteristic is exploited in certain specialized applications.
-
Ease of Fabrication: Despite its strength, niobium is easily formed, welded, and machined, facilitating its use in complex engineering designs.

Parameters of Niobium 99.95% Pure Niobium Bar / Ingot / Metal / Block / Rods Per Kg
Niobium, with a purity of 99.95%, is a high-quality metallic element often used in various applications due to its unique properties, such as superconductivity and corrosion resistance. Here are some key parameters for a typical niobium bar, ingot, metal block, or rods per kilogram:
1. **Density (ρ)**: Niobium has a density of approximately 8.56 g/cm³ or 8,560 kg/m³ at room temperature. This means that a 1 kg piece would have a volume of about 117.24 cm³.
2. **Melting Point (Tm)**: The melting point of pure niobium is around 2,730°C (4,946°F).
3. **Boiling Point ( Tb)**: There is no defined boiling point for elements like niobium in a vacuum; however, it sublimates directly from a solid to a gas at pressures below its triple point, which is around -206.9°C (-338.0°F) and 0.013 Torr.
4. **Magnetic Properties**: Niobium is diamagnetic, meaning it weakly opposes an external magnetic field and does not become ferromagnetic.
5. **Mechanical Properties**: It is a strong, ductile metal with good machinability, but it can be brittle at low temperatures. Young’s modulus (an indicator of stiffness) is approximately 115 GPa (16.6 x 10^6 psi).
6. **Thermal Conductivity (λ)**: Niobium has excellent thermal conductivity, with values around 110-120 W/m·K, making it suitable for heat transfer applications.
7. **Superconducting Properties**: When cooled below the critical temperature (typically below 9.2 K for niobium-titanium alloys), it exhibits zero electrical resistance and perfect diamagnetism, making it ideal for superconducting magnets and other high-tech applications.
8. **Price**: The cost of 99.95% pure niobium varies depending on market conditions, availability, and the form (bars, ingots, blocks, or rods). It is generally more expensive than most metals due to its specialized uses.
Please note that specific dimensions, shapes, and surface finish of the niobium bars/ingots/blocks/rods may also affect the price and some parameters, such as surface area and weight per unit length. For detailed pricing and specific dimensions, you would need to consult a supplier or check current market data.
