Disadvantages Of Rare Earth Metals

Introduction
Rare earth metals are a fundamental part to many modern technologies, they are found on the earth 's crust. Without these metals we would not have access to electronics, clean energy, communications, networks, modern transportation systems, health care, national defences and etc. The need for these metals are rising but theses metals are vanishing and the demand keeps getting higher. These metals differ from others as they are luminous and magnetic as well as having the ability to create electricity. They allow us to create electronics or technologies that have minimum weight (considering size) and reduce energy consumption. Rare earth metals are also efficient, fast, durable and can hold many temperatures without it being damaged. These elements have helped us grow as humans with the amount of technology used with the help of rare earth metals and if used in a good

Terbium plays a huge part in national defence systems which is vital for a developing country. As mentioned before anything in need of a motor is an object reliant on terbium this means the manufacturing of any government Cars and weapons this also goes the same for jets tanks and any other vehicle used in the countries defence in the worst case scenario. But, this also applies to communications politically as terbium is used for circuits which act as the mind of a phone. Communications help countries make peace and come to terms with each other as one leader can speak to another also communications are used to reinforce law and order within the country as mentioned before. It allows policemen, firefighters and paramedics keep in touch with their stations/ hospitals to make sure everything happens correctly and lawfully and to keep people safe and protected within the country. It is also used in targeting systems for large weaponry and is important part of F-16 fighter jets which are jets that don 't require a person flying
