Tantalum | Ta Metal | Properties | Applications

Tantalum is a rare element that is highly prized for its applications in industry and emerging technologies. As a refractory metal, tantalum has a very high density (16.7 g/cm 3 at room temperature), a very high melting point (3017 C), and good mechanical strength at high temperatures.. Tantalum stands out from other refractory metals due to its extreme chemical inertness and electrical ...

Tantalum | Plansee

Tantalum occurs most frequently naturally in the form of tantalite ore which has the formula (Fe,Mn) [(Nb,Ta)O 3] 2. When the tantalum content predominates, the ore is referred to as tantalite. When more niobium than tantalum is present, it is known as columbite or niobite.

Niobium Oxide Advantages over Tantalum as a Capacitor ...

Abundance: an important advantage of niobium is the abundance of niobium ore in nature relative to tantalum ore; this relative abundance equates to lower cost and better availability within the capacitor marketplace. Flame Retardant: niobium oxide has a far higher ignition energy than tantalum which results in a significant reduction (up to 95% ...
