Overview of Ta2O5 powder Tantalum pentoxide powder for optical vacuum coating
Tantalum (Ta) is a chemical element with the atomic number 73 and is symbolized as Ta on the periodic table. It is a dense, blue-gray, hard, and ductile transition metal. Discovered in 1802 by Anders Gustaf Ekeberg, tantalum is renowned for its high resistance to corrosion and its ability to store and release electrical charges efficiently, making it a critical material in various high-tech applications.
Feature of Ta2O5 powder Tantalum pentoxide powder for optical vacuum coating
-
Exceptional Corrosion Resistance: Tantalum forms a protective oxide layer that shields the metal from most acids, even at high temperatures, and is virtually impervious to chemical attacks.
-
High Melting Point: With a melting point of approximately 3,017°C (5,462°F), tantalum ranks among the metals with the highest melting points, enabling its use in extreme temperature environments.
-
Biocompatibility: Tantalum is well-tolerated by living tissue, making it suitable for biomedical implants such as bone replacements and surgical sutures.
-
Electrical Conductivity: Although not the best conductor, tantalum has a high capacitance per volume, making it ideal for manufacturing compact capacitors used in electronic devices.
-
Ductility: It can be drawn into fine wires and fabricated into various shapes without fracturing, a feature that enhances its versatility in manufacturing.

Parameters of Ta2O5 powder Tantalum pentoxide powder for optical vacuum coating
The parameter of Ta2O5 powder and tantalum pentoxide powder for optical vacuum coating is typically determined by the specific requirements of the coating application. The parameters that you might consider include:
1. Film thickness: The thickness of the coating film is important because it affects the reflectivity, transparency, and durability of the final product.
2. Coating composition: The composition of the coating can also affect its properties, such as its solubility in various mediums and its ability to withstand exposure to UV light.
3. Vacuum pressure: The pressure of the vacuum chamber used for the coating process can impact the layer thickness and coverage rate.
4. Temperature: The temperature of the vacuum chamber and the materials being coated can affect the chemical reactions that occur during the coating process.
It’s best to consult with a manufacturer or expert in the field for specific information on these and other parameters that may be relevant for your particular coating application.
