It looks like glass and feels like glass; This is a unique dragon crystal ceramic!
The patent for Xiaomi ceramics is available, but it is classified as glass.
Xiaomi 14ultra Longjing Ceramics Stirs Up Controversy Recently, the problem of Xiaomi 14ultra Longjing ceramics has been boiling. Some up owners said that the Longjing ceramic plate was glass, and he also used the kind of pen of Mohs hardness paint to test the hardness of the back cover of Xiaomi Longjing ceramic.
As a result, scratches began to appear at level 6 and more noticeable at level 7.
The hardness of ceramics is almost 8 on the Mohs scale, and then the glass can only go to about 6, so in terms of hardness, Xiaomi is very much like glass rather than ceramic.
Scratch it open at the back and find that it is transparent, and the reason why it appears is because it is painted, which now looks more like glass, unless Xiaomi redesigns the transparent ceramic.
The rigorous up master made a sub-section electron microscope diagram of the Xiaomi 14ultra Longjing ceramic back cover.
The spherical shape in the figure is the microcrystalline grain, and the preliminary analysis results show that there are two crystals with the highest internal content: lithium feldspar Li[AlSi4O10] and lithium disilicate Li2Si2O5.
To explain,Lithium disilicate is a ceramic material。If the content is more than 50%, it is actually ceramic. Meatballs with no beef content bought in the market can only be called beef flavor balls, but if the content exceeds 50%, the first place in the ingredient list is beef, and it can be called beef balls.
The specific proportion needs to be confirmed after a variety of methods to assist in refinement, and more detailed tests are done after the preliminary test. Just this behavior of daring to question, dare to speak out, and dare to practice, I think it is very admirable!
Doing a test is rigorous, everything is based on data, and science cannot tolerate fraud.
Recently, this result has finally come out after a long time, and it can be regarded as a finale.
The laboratory's test report shows that the first place is lithium feldspar Li[AlSi4O10] with a content of 43%, and the second place is lithium disilicate Li2Si2O5 with an overall content of 34%, which is similar to the above.
After analysis, the third aluminosilicate content is 11%, in addition to this there is 12% amorphous image in the material, that isThe crystal content in Longjing ceramics is about 88%, and the amorphous content is about 12%.
Someone asked about 88% crystal content, so isn't this considered ceramic?
No, Huawei's glass-ceramic patent has a crystalline content of 90% and a stronger hardness, and it doesn't dare to call it Kunlun ceramics.
It is basically concluded that Xiaomi Longjing ceramics belong to glass-ceramic.
But don't think about going to fake one to lose three, ceramics is a big category (cement, glass are counted) if you analyze Xiaomi Longjing ceramics from this point of view; It can only be said that it can be ceramic, not glass, and the face is saved, but at what cost?
Personally, I think the key issue in the whole thing is publicity.
Is it ceramic or glass? Because the definition of ceramics and glass itself is not very clear, glass-ceramic is originally a product of combining the characteristics of glass and ceramics, and now the noisy "traditional ceramics, national standard classification, crystal content" and so on, the conclusions are different, that is, "Longjing ceramics" may not be pure ceramics, but a material similar to glass-ceramic, or a composite material made of ceramics and glass.
So whether it is glass or ceramics can only be judged, and no one can convince anyone.
At the Xiaomi press conference, it first mentioned the previous ceramic version of the back cover, and then compared the weight with traditional ceramics, but did not mention the hardness, and then said that after two years of research and development, the technology of reducing the weight of ceramics by 50% was obtained.
But this "technology" is actually realized with another material instead, and it also takes the name of Longjing ceramics, which is a bit bluffingIn fact, it does not have the texture and hardness of traditional ceramics, and it is similar to dragon crystal glassIt's a thing.
If you use glass materials to make a ceramic texture, and you don't add money on this basis, it belongs to innovation or conscience. But Xiaomi is playing with words, taking advantage of the public's ignorance of the properties of materials to brag about itself!
The user buys the feel and wear resistance of the ceramic, rather than the word "ceramic", and all aspects can not meet the requirements of ceramics, even if this is the scientific definition of ceramics, who will pay for it? What about the name "ceramic"?
In the past, I thought that the extraordinary master was engaged in marketing, and the parameters of the mobile phone were not upgraded much to make a ceramic appearance, and a spokesperson dared to buy tens of thousands of yuan, but now I found that the ceramic process was so complicated, and it can really be blown.
At least in terms of hardness, people are closer to the 8-level hardness of ceramics.
Sooner or later, the publicity will be seen through by grasping the loopholes in the law, and when the time comes, it will ruin consumers' good impression of them.
Before, Xiaomi's claim was thinner than a one-yuan coin, and you can't say that people are wrong, but no one thought that the coin was hard, and the result was such a comparison method.
There are always some loyal rice fans who say that any problems with Xiaomi will be put under a magnifying glass to observe. What moved the cake of too many people, so it was hacked by friends!
The market is that everyone is moving someone else's cake, Honor is moving Huawei's cake, Huawei is also moving Apple's and Samsung's cake, and OPPO is also moving Meizu's cake. Looking at a larger scope, BYD Qin's price reduction is not only to move BMW's cake, but also to move the entire rim cake.
Someone is going to hammer him for quality?
I have always believed that in a fully competitive market, enterprises may buy propaganda and engage in black materials, which is the business method chosen by others, as long as they do not violate the law and do not interfere too much.
The problem of product quality is the bottom line, and it is also illegal, and it must be taken out.
So fans don't say that there is a problem and wash it, and caring for the brand is not blindly conniving. If there is a problem with the product, the correction is, not to mention making it a "lonely hero" image, as if the whole world can't get along with my "brother".
It's a brand, and if the problem exists, it exists, not as if it's not seen.
Ceramics in a broad sense are also ceramics though! ButTechnology is not wordsThis "Longjing ceramic", which is not hard enough, is not the ceramic in the hearts of consumers, just like a basin of boiled water with a few drops of meat can also be said to be a pot of broth, but this is not the bowl of soup that everyone wants.
