Hafnium sheets used in the electronic industry need to have a high melting point (≥ 2200 ° C) and excellent thermal stability to withstand high-temperature process environments in electronic device manufacturing, such as sputtering or annealing processes. Its high-temperature oxidation resistance ensures structural integrity at extreme temperatures, making it suitable for semiconductor packaging and power electronics fields.

Good conductivity and thermal conductivity are required to support the current transmission and heat dissipation needs of electronic components. Meanwhile, high hardness (such as hafnium carbide Mohs hardness>9) and wear resistance can extend the lifespan of devices, making them suitable for high-frequency circuits or miniaturized components. In addition, the room temperature tensile strength needs to meet the standard (such as Rp0.2 ≥ 150MPa) to ensure processing reliability.

Nuclear grade hafnium plates require a Zr content of ≤ 3.5% and U impurities of ≤ 0.001%, while the electronics industry typically requires higher purity (such as 5N grade) to reduce the impact of impurities on semiconductor performance. The preparation process requires the use of vacuum melting or double melting technology to ensure density and uniformity of composition.

In specific applications (such as high-K dielectric materials), it is necessary to achieve high dielectric constant (20-25) through hafnium oxide (HfO ₂) coating to reduce chip power consumption and improve integration. In addition, corrosion resistance can adapt to complex chemical environments, such as etching processes in PCB manufacturing.

Hafnium sheets used in the electronic industry have solved the extreme requirements of semiconductor equipment for material corrosion resistance, cleanliness, and thermal stability through ultra-high purity control, precision machining, and surface optimization technology. Its application is directly related to the process accuracy, device reliability, and production line cost of chip manufacturing, and is a key material support for promoting the development of advanced processes.
