Apple recently tends to use dense sapphire glass in its products, as it used it in the iPhone 5s camera, as well as as protection for the fingerprint sensor in the home button of the same device, and every week we read rumors about Apple's intention to expand its dependence on it to reach the protection layer in its upcoming devices. But hey !!! What is this sapphire glass that we read and hear about every day? And is it a strong match that might replace Corning's famous gorilla glass? and What is the difference between them? And many other questions touring the minds of readers, so we decided to single out an article on “Sapphire” glass, to get to know it closely and find answers to these questions.
What is Sapphire glass ??
Sapphire or Sapphire: It is a type of sapphire that contains aluminum oxide (Al2O3It is usually worn as a type of jewelry, but due to its remarkable toughness it has been used in various industries such as valuable wristwatches, high-spec windows, and others. Glass goes through an intensive manufacturing process at a high cost until it is molded to suit the surface to be used.
Despite the cost of sapphire glass, it has wonderful properties that are desirable by companies. It has very high transparency and is more durable than ordinary glass. The number means that it is one degree lower than the hardness of diamond (which got 9/10 on the same scale) and more than the hardness of the Gorilla Glass, which got 10/10 in the Mohs scale, in addition to its high melting point of 7 degrees Celsius, which makes it resistant Strong heat, which makes it ideal for use with lamps and laser tubes, it is also resistant to acids and other caustic substances.
From all of the above we conclude that sapphire glass is the best use if the leaks are believed and Apple used it in the iPhone 6 as a front end, and given what we heard about Apple's investments in it and the start of its production in a factory in Arizona, these things are almost certain that it will be used in a product coming from Apple, which is either the iPhone IPhone 6 or smart watch. You can watch this video to learn more about the strength of sapphire glass that will amaze you ...
Comparison between it and Gorilla Glass
Gorilla glass is currently the most popular and is used by most smart phone manufacturers because of its light weight and lack of thickness and cost, and this is what the gorilla glass excels in, especially in terms of cost. Analysts said that the average cost of a bottle of phone from Sapphire is $ 30 (some analyzes expected it to drop to $ 12), while the same size bottle of gorilla costs $ 3. From here it is more likely in any price calculations, but in terms of strength, it does not reach the strength of sapphire glass in endurance, so as we mentioned that the gorilla got a 7 in the scale of Moose while the sapphire glass got a 9 and this is a big difference between them, and as you saw in the video above what happened when it was scratched Sapphires and gorillas.
Could it be a viable alternative to Gorilla Glass?
It is expected that these leaks will be believed, especially after Tim Cook admitted in an interview that they manufacture large quantities of sapphire glass, but will Apple use it in a limited way, as it currently does in the lens and fingerprint? Is it for the smart watch? Or will it be for the iPhone 6 ?! For this to happen, Apple must overcome some obstacles, such as the one published by the Research Center, which it stated are the disadvantages of Sapphire compared to the gorilla:
- Up to 10x high cost.
- 1.6 times the weight of Gorilla Glass.
- Less transparent to light than the gorilla, which may affect the colors in the screen, and this means that Apple must adjust the screens to fit the "sapphire".
- Sapphire glass is not environmentally friendly.
- Gorilla Glass withstands 2.5 more pressures than Sapphire. The latter is more resistant to scratching, but the former is more stressful.
