牙合是一种金属元素，具有化学符号TE和原子数52。它主要用于加工过程中及其周围的铁，铜和铅合金。当将其添加到不锈钢和铜中时，它们使最终的合金更加可加工。当添加铅并限制其典型的腐蚀作用时，它还增加了强度和耐用性。尽管在过去的40年或更长时间以上（见下文）中，用于柜员的主要用途一直是恒定的，但科学也为旧元素创造了一些新用途。亚博老虎机网登录

钢铁工业
在过去的40年或更长时间的时间里，柜员的主要用途是钢铁制造业。超过50％（来源：USGS）或更多的最师端使用，仍然用作铁和钢的合金剂。在钢中添加约0.04％的柜子可改善制造特性，例如弯曲，切割，塑造和转弯。
Photovoltaics
The National Renewable Energy Laboratory (NREL), located in Golden Colorado and a government-owned and contractor-operated facility, has tested Tellurium (used in cadmium telluride) for use in solar panels. Cadmium Telluride (CdTe) achieved some of the highest efficiencies for solar cell electric power generation. In fact, cadmium telluride is the first and only thin film photovoltaic technology to surpass crystalline silicon PV in cost effectiveness primarily in multi-kilowatt systems.
Other Applications
廉洁的其他用途包括：
- 作为通过Movpe（金属有机蒸气相外延）实现CDHGTE低温生长的首选前体，这反过
- 介质在介质中使用柜子作为柜子亚氧化物，用于几种可重写的光盘，包括CD-RW，DVD-RW和可重写的蓝光光盘。
The Future of Tellurium
While the vast quantities of Tellurium have been used in the production of metals such as steel, it is likely that this will remain the main use into the near future. As the efficiencies of solar cells improve with more research, the business case for solar cells becomes stronger along with government mandates for clean energy. Lower cost and government regulations should open up the possibilities and make it easier to develop business cases for using solar energy over the next decade thereby increasing the need for Tellurium in that industry as well.
