99.95 % Platinum Metal Rod

Product Description

Overview

99.95% Platinum Metal Rod is a metal product made of high-purity platinum metal or platinum alloy material. It has good ductility, high temperature stability, conductivity, and catalytic activity. It can be widely used in electronic components, the automotive industry, aerospace, the petrochemical industry, environmental protection engineering, the pharmaceutical industry, jewelry,y and other fields.

Advantage

• The melting point of platinum is as high as 1768.3 °C, and it can still maintain a stable physical form in an extremely high temperature environment, and is not easy to melt or deform.
• High density, high hardness, good ductility, and high plasticity can be achieved through forging, rolling, and other processes of different sizes of the bar.
• Platinum has a low Coefficient of thermal expansion at high temperatures (about 8.8 × 10-6 °C) and good dimensional stability, making it suitable for use as a structural material at high temperatures.
• Platinum almost does not react with any chemical substance at room temperature. It has high corrosion resistance to acid, alkali, salt solution, and most organic solvents.
• Platinum is a kind of high-efficiency catalyst, which can catalyze the chemical reaction of hydrogen, oxygen, carbon monoxide, and so on.
• Platinum has excellent Biocompatibility, does not react with human tissues, and can be placed in the body for long periods.

Application

1. It is used as an inert electrode in electrochemical experiments (such as electrolysis and potentiometric titration), because of its strong corrosion resistance and its inability to participate in chemical reactions, which ensures measurement accuracy.
2. It is used as the electrode of a precision temperature sensor and is widely used in industrial temperature measurement and scientific research equipment, such as low-temperature physics experiments and high-temperature furnace temperature control.
3. A 99.95% platinum metal rod is used as a catalyst, often combined with palladium, rhodium, and other precious metals, to promote the purification of automotive exhaust and reduce emissions.
4. It is used in the evaporation process to form a conductive layer or a barrier layer on the chip surface, or as a sputtering target to prepare a platinum thin film for microelectronic devices.
5. They are used as temperature compensation resistors or precision resistors in high-temperature environments, such as aircraft engines and industrial kilns.
6. A platinum metal rod can be processed into fine needles or wires for medical implants, such as pacemaker electrodes and nerve stimulator leads.

Dimension

Process

① Reduce and purify platinum metal materials, control single impurities, and facilitate subsequent processing.

② Melt metal in a vacuum furnace and cast it into a platinum ingot.

③ Heat the platinum ingot to 800~1200℃ and process it into a bar billet by forging or rolling.

④ Use a diamond tool to precisely turn the outer circle of the bar, and the diameter tolerance is controlled at ±0.01 mm.

⑤ Annealing treatment to eliminate cold working stress and restore plasticity.

⑥ Electrolytic polishing to remove the oxide layer and micro burrs, and the surface finish reaches a mirror effect.

⑦ Comprehensive quality inspection, such as purity, dimensional accuracy, mechanical properties, etc.
