Tantalum was extensively used in the production of ultra high frequency electron tubes for radio transmitters. Tantalum is capable of capturing oxygen and nitrogen by forming nitrides and oxides and therefore helped to sustain the high vacuum needed for the tubes when used for internal parts such as grids and plates.
Tantalum pentoxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta 2 O 5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Ta 2 O 5 is an inert material with a high refractive index and low absorption (i.e. colourless), which makes it useful for coatings ...
India was a net energy importer to meet nearly 47% of its total primary energy in 2019. [3] [4] While much of its energy comes from fossil fuels, as of 2024, India is in the midst of a very rapid growth of solar and other renewable energy. However, this page currently only discusses the country's fossil fuel–based energy.
A Rwandan official discussing prospective mines in his country said that Canada had 4% of global production in 2009; but in rock so hard that the ore is too expensive to extract. In 2009, Rwanda had 9% of the world's tantalum production. [13] In 2016, Rwanda accounted for 50% of global tantalum production.

Because Tata won its bid on the promise to sell energy at a certain price, it now loses money on every kilowatt it generates at the plant. In 2013, at the company’s request, a federal agency approved a 23 percent rate hike. The increase was blocked last year, at least temporarily, by India’s Supreme Court.
In 2018, India's net imports are nearly 205.3 million tons of crude oil and its products, 26.3 Mtoe of LNG and 141.7 Mtoe coal totaling to 373.3 Mtoe of primary energy which is equal to 46.13% of total primary energy consumption. India is largely dependent on fossil fuel imports to meet its energy demands – by 2030, India's dependence on ...
