<p><b>New page</b></p><div>[[File:Microlite-bem-42a.jpg|Microlite-bem-42a|thumb]] '''Microlite''' refers to a group of [[mineral]]s within the [[pyrochlore]] supergroup, which are [[oxide mineral]]s with the general formula (Ca,Na)_2Ta_2O_6(O,OH,F). Microlite is characterized by its high [[tantalum]] content and is an important [[ore]] of this metal. The mineral is typically found in [[pegmatite]]s associated with [[granite]], and its formation is linked to the late stages of the crystallization process of these intrusive rocks.<br />
<br />
==Properties==<br />
Microlite is known for its isotropic properties, exhibiting a range of colors from yellow to green, depending on its composition. The mineral has a Mohs hardness of 5 to 5.5, making it relatively hard but still susceptible to scratching by harder substances. Its specific gravity ranges from 4.2 to 6.3, which is high, reflecting its dense nature. Microlite crystals are usually small, hence the name, which is derived from the Greek for "small" and "stone."<br />
<br />
==Occurrence==<br />
Microlite is primarily found in [[pegmatite]]s, which are coarse-grained igneous rocks. These pegmatites form during the final stages of magma crystallization and are known for containing rare minerals, including microlite. The mineral is often associated with other tantalum and niobium minerals, such as [[columbite]] and [[tantalite]], and can also be found alongside [[quartz]], [[feldspar]], and [[mica]].<br />
<br />
==Uses==<br />
The primary use of microlite is as a source of [[tantalum]], a metal highly valued for its use in electronic components, such as capacitors and high-power resistors in mobile phones, DVD players, video game systems, and computers. Tantalum's high melting point and resistance to corrosion also make it useful in the manufacturing of aircraft engines, missile parts, and nuclear reactors.<br />
<br />
==Environmental and Ethical Concerns==<br />
The mining of tantalum ores, including microlite, has been linked to environmental degradation and ethical issues, particularly in conflict regions. The extraction process can lead to deforestation, soil erosion, and contamination of water sources. Furthermore, in some areas, the tantalum mining industry has been associated with funding armed conflict and violating human rights, leading to calls for the ethical sourcing of tantalum and other minerals.<br />
