The metal has several important uses in industrial chemistry, as industrial catalysts and in chlorine production.ĭespite its rarity, consumption of iridium continues to increase. Interestingly, iridium was also used to create the standard meter bar used to measure the unit of distance from 1889 to 1960. Another valuable physical property is iridium’s ability to resist corrosion, which is why the element is used to grow crystals for LED lights. Due to its high melting point and low reactivity, iridium is used as the contact in spark plugs. Iridium is one of the rarest elements on Earth, but can be found in one of the most ubiquitous aspects of modern life – the car. This information was what allowed scientists to develop the hypothesis that an asteroid impact caused the extinction of dinosaurs 65 million years ago (See Alvarez hypothesis). Iridium in the clay layer that created the boundary between the cretaceous and tertiary periods (KT boundary) was 30 times greater than the amount expected. Normally, iridium rains down on Earth in meteorite dust at a fairly constant rate. While crustal abundance of iridium is estimated at 0.001ppm, the concentrations are much higher in asteroids. Department of the Interior, iridium in the Earth’s crust is thought to have come from the same asteroid or comet believed to have caused the extinction of dinosaurs. SatPhoneStore has been connecting customers since 1976 and is standing by and ready to help you find the best satellite phone to meet your communications needs.According to the U.S. Navigating all the options for satellite internet can be confusing and complex, but SatPhoneStore makes it easy by providing thorough information online, an in depth knowledge base, online chat and agents available by phone to help users make informed decision and choose the solution that is the best fit for their needs. Some sat phone users have a need for data as well. Satellite phones are easy to use, but they work a little bit different than the cellular phones people are generally used to, so SatPhoneStore provides quick start guides and has a knowledgeable customer care team available seven days per week to help its users get connected. For that reason, there are docking stations or repeaters available for most satellite phone models on the market. For a sat phone to work inside a building they must be connected to an external antenna. Satellite phones need to have a direct line of sight connection to a satellite in order to successful connect a call. Most sat phones don’t have cutting edge touch screens, high end camera technology or apps, but they do work in areas and situations where cellular connected phones do not. Satellite phones don’t boast all of the features found in today’s smart phones. Satellite phones are also used by first responders, public safety professionals and organizations that have a need to stay connected during and after a natural disaster or other wide spread communications outage. Those who need to communicate out at sea, in the air or in other remote locations find that sat phones are often the only means available to stay connected with the rest of the world. Satellite phones have become a significant communications options for those who need to communicate while off the grid or have a mission critical communications need.
