Kazera owns a 75% stake in African Tantalum Pty Ltd, owner of Namibia Tantalite Investments - which holds the operating assets and plant - and Tameka Shelf Co, owner of the title and licences to Tantalite Valley.
Tantalum is an innovator in the connected car space as an end-to-end services provider.
Besides ESR increasing and capacitance loss after long-term operating at high temperature, tantalum polymer capacitors also suffer electrical parameter deviation at elevated temperature, such as capacitance instability and DC leakage current increasing.
During the milling process, the ceramic phase affects the crystallographic parameters of the tantalum (Figure 4(a)) and vice versa--the tantalum affects the crystallographic parameters of the ceramic phase (Figure 4(b)).
Tantalum says that this can allow for fairer road charging based on actual emissions as well as giving city planners valuable data to build cleaner, smarter and healthier cities.
The Glow Discharge Optical Emission Spectroscopy (GDOES) measurements on PEO oxidized tantalum samples were performed on a Horiba Scientific GD Profiler 2 instrument using radio frequency (RF) asynchronous pulse generator with the following conditions: pressure: 700 Pa, power: 40 W, frequency: 3000 Hz, duty cycle: 0.25, and anode diameter: 4 mm.
Tantalum capacitors are essential in low distortion circuits and circuits that require a large bulk capacitance, and it should come as no surprise that embedded tantalum capacitors are needed to satisfy advanced designs.
Dramatically reducing the footprint of tantalum capacitors required the restructuring of the entire manufacturing process, as several of the capacitor construction features restricted the size of the tantalum anode that can be utilized within a given package size.
Unique surface treatment: Tantalum is one of the most corrosion-resistant metals, but it is also very costly, making solid-tantalum heat exchangers extremely expensive.
According to the BBC, 'conflict minerals', as they are known, are mined in areas of fighting or human rights abuses, such as the Democratic Republic of Congo and most electronic devices contain either gold, tantalum, tin or tungsten, whose mining is often controlled by violent militias who may profit greatly from the activity.
Apple has announced that its suppliers do not secure the mineral tantalum from sources that fund violent armed groups.
