The hardest material naturally produced is diamond (that is, sparkling diamond), and the Mohs hardness can reach 10, followed by corundum, and sapphire is one of them, but the price of natural sapphire is high and the output is low. Generally used as jewelry. Naturally, no. Can they be synthesized? As a result, an artificial product with the same composition as sapphire but lower price came out-sapphire glass.
Although sapphire glass is hard, it is not absolutely reassuring. In fact, there are many substances in the world that are much harder than sapphire, whether natural or man-made, so sapphire glass will not really make you feel indestructible, and there is still the risk of being scratched, but there is no need to be nervous about it. As long as the scratches are not deep, it generally does not affect the performance of the camera, and imagine that for such a good lens of Samsung mobile phone, people will not use sapphire as the lens surface. Is it still in use? Huawei calls for surpassing Apple's Samsung every day, and sees no sapphire glass. However, it should be noted that sapphire glass is easily broken, and the lens of ip7 is so prominent and enlarged this time, so it is better to be careful when using it.
