What is Tantalum Powder: A Comprehensive Guide for Buyer
What is Tantalum Powder? A Brief Overview
Tantalum powder is the finely ground version of elemental tantalum, distinguished by its steel-gray color. It is denoted by the chemical symbol 'Ta' and plays a crucial role in various industrial applications. Tantalum, positioned in Group VB of the periodic table, has an atomic number of 73 and an atomic weight of 180.9479. It forms a body-centered cubic crystal structure.
The hardness of tantalum powder is relatively low, and it is closely linked to the oxygen content in the material. In its annealed state, pure tantalum shows a Vickers hardness of around 140HV. One of its most significant properties is the high melting point, reaching approximately 2995°C, which makes it valuable for high-temperature applications.
