Glass? Ceramics? Silly and unclear? Xiaomi's car is a bit powerful!
What's going on?
Recently, technology blogger @victory文绉crepe publicly "cracked down" on Weibo about the back cover material of the Xiaomi 14 Ultra,It is suspected that it is not made of ceramic, but glass-ceramic (which can also be called "ceramic glass").
As soon as the news came out, many netizens blew up. 3000+ floors have been built on Ku'an. Someone with his hands in his pockets, indicating that he doesn't care, that's all? What a big deal......
Some people were indignant and expressed their disappointment with Xiaomi and would never buy ...... again
However, everyone wait, calm down first. This melon really makes the dark horses eat one by one. Glass or ceramic? Need to distinguish? There must be friends who will ask,Why do we have to distinguish between the material of the back cover of the Xiaomi 14 Ultra, which is glass? Or ceramic? No matter what material the back cover is, it won't affect my use, what's the point? emmm……It's true that some users don't care much about this. However, Dark Horse also knows that there are indeed some users who will choose whether to buy this mobile phone because of the back cover material and frame material of the mobile phone. If they buy the Xiaomi 14 Ultra for the point of ceramics, they will be disappointed if they are "faked". 
At present, there are various materials for the back cover of mobile phones, mainly plastic, metal, glass, leather, and ceramic. For users, the main difference between these materials is the feel of the touch, and its drop resistance and wear resistance. Why do you care about glass or ceramic backs? It is because the ceramic back cover is more moist and textured than the glass back cover in terms of feel, and at the same time, the ability to resist falling is stronger, and it is also more wear-resistant, and it is not easy to scratch. Therefore, for "obsessive-compulsive disorder" like a dark horse that can't see the scratches on the mobile phone, ceramics are better. "Longjing ceramics" is not equal to ceramics? But so be it! But! Here's the problem. According to the @Shengliwen crepe test, the "Dragon Crystal Ceramic" back cover of Xiaomi 14 Ultra is not as wear-resistant and scratch-resistant as everyone imagined. At 6 on the Mohs scale, slight scratches appear, at 7 scales, the scratches become noticeable, and at 8 scales, the scratches are especially visible in front of the camera. 
In contrast, the Huawei Mate60 RS, which also uses a ceramic back cover, only showed obvious scratches when it reached level 8 during the Mohs hardness test. (Although it doesn't lead to war, it does hurt ...... if there is a comparison.)Moreover, the blogger said that the mainstream material used to make ceramic back covers for mobile phones is zirconia (ZRO), which has a hardness of at least 7 on the Mohs scaleLevel 5. In this way, Xiaomi's ceramic back cover obviously does not meet the standard of zirconia. Therefore, it is very likely that "Longjing ceramics" are not real ceramics. This hardness has to be said to be very glassy ......
In addition, @胜利文绉绉初步断定 "Longjing Ceramic" is not equal to the basis of ceramics, and the back cover of Xiaomi Mi 14 Ultra's "Longjing Ceramic" is colored, which is similar to the coloring process of the glass back cover; The weight is almost half that of other ceramic backs, and not much different from the weight of glass backs. Of course, this is actually the return of this generation of Ultra with a ceramic back coverThe biggest highlight is the 50% reduction in weight. This point is put on the bright side, and the dark horse feels that it is not enough to be a basis. 
What's even more interesting is that the Xiaomi Mi 14 Ultra's "Dragon Crystal Ceramic" in the XRD test, the analysis results generated by it are the same as the "Dragon Crystal Glass" on its front. Ah, that's a bit of a coincidence. 
Plus the SEM test results of the Xiaomi Mi 14 Ultra "Dragon Ceramic" backplateThe blogger's final preliminary conclusion is that it is a piece of "glass-ceramic" with petalite feldspar. Of course, this conclusion has not yet been hammered. 
Xiaomi: There is no wife in the wife's cake, normal; Longjing ceramics are non-ceramic, and they are also normal. (Infinite Dog Head.) jpg）Xiaomi marketing overturned? Clinches? Having said that, Xiaomi officials have not yet responded to the controversy over whether "Longjing Ceramic" is ceramic or glass. But when the dark horse asked Xiaomi official ***,The answer is ceramic
*From**@胜利文绉绉的最终报告, it should come out tomorrow, so the blogger's questioning can only be said to be "reasonable questioning", and it can't be finally hammered! Tomorrow, everything could be reversed! Of course, even if it doesn't ...... reversedXiaomi's PR should still be able to come back. Theoretically speaking, from the perspective of materials science, the presence or absence of crystals is the criterion for distinguishing ceramics and glass, and dragon crystal glass must be a crystal structure. Even if it's a ...... that melts into it later
Of course, it may also be a new technological ceramic, which is also available at the moment, but some people still feel cheated. Science and technology leather are marked with technology, why not science and technology ceramics marked with technology? If this theory is really rounded, I am afraid that for users, the brand trust of this brand will have to fall another notch. Even if the circle comes back theoretically, everyone's hearts are probably not very comfortable. And, do users care about theoretical results? Everyone is obviously more concerned about the actual experience, anti-wear and scratch resistance. However, the ceramic backplane process, for Xiaomi, is not difficult, and previous generations of products have been used. The Xiaomi 14ultra, which has an average price increase of 500 for the whole series, will not really save this. After all, this is Xiaomi's image super cup, which is not good? So, what's the secret of this?
Finally, let's let the bullets fly a little longer. What about a rollover or a rollover? What do you think? However, this time, there is still damage to the Xiaomi brand, and Mi Chonggao's plan to rush to the top has to be dragged down. Next, it depends on Xiaomi's marketing and PR capabilities.
