Apple has recently reportedly invested in a new type of smart device screen technology. 9 to 5 Mac Writing, The company’s ‘Sapphire Crystal’ screening plant will be launched by the end of this month. But what is this sapphire crystal thing? In this post we will learn about Sapphire Crystal.Sapphire Crystal
Sapphire is a very hard (super-hard) and transparent form of crystal that looks like glass or diamond. It is also known as ‘Nilkant Mani’. Sapphire crystals are available in yellow, purple, green, red, blue and other colors. In most cases, the gem is bluish.
But will the screen of iPhone be blue?
Very reasonable question. In fact, pure sapphire crystals have no color. The presence of metals like iron, titanium, chromium, copper, magnesium etc. in the substance makes it colorful. If Sapphire Crystal is used in iPhone, it must be so pure that it will be colorless and transparent like ordinary glass.
Where are the sapphire crystals found?
In general, sapphire crystals, like other gems, are extracted from mines. However, sapphires that are used in cases other than ornaments are made artificially. The world’s first synthetic sapphire crystal was made in 1902. The French chemist August Vernoul was the first to be able to make the substance artificially. When aluminum oxide is applied at high temperature and pressure, it converts into crystals. It is resistant to scratches or stains. Sapphire crystals can also be used on bullet-proof car windows because they are too hard. Usually the scale of steel’s ‘Mo rating’ (the unit of hardness in the case of minerals being ‘Mo’) ranges from 4 to 6 (extremely hard). And Sapphire Crystal’s ‘Mo’ rating is expected to be 9. So one can be sure of its firmness. Although the Mo rating of the glass made by Corning has not been published, it is expected that the Mo rating will be 8.
Good but the price?
The only reason Sapphire Crystal is not used in smartphones or other consumer electronics is because of its high cost. Glass manufacturer Corning claims that Sapphire Crystal will cost 10 times more than current Gorilla Glass. However, if Apple did use the substance in their devices, the company would take steps to ensure that gadgets do not cost more than current prices. However, we will have to wait a few more days to see what actually happens.
