This "silicon" actually contracted half of the gem world.
The year before, I suddenly found out that the correct way to describe a person’s wealth is to contract a woman’s fish pond. Yes, the smile of the Tang dynasty is still a nightmare for Xiaobian. Last year, I suddenly found out that the correct way to describe a person's merits is to say that he has propped up half of China's rock and roll. That's right, Wang Feng's "Spring" is still a must-choice for Xiaobian. Today, Xiao Pan discovered a gui grandson who contracted half of the gem world! Have to talk to everyone! And the one I want to introduce today is a veritable gui grandson, silicon dioxide (SiO2). However, you found that the crystal is transparent, and the agate is opaque. Why is the main component silica? Let's talk to you about how this product has changed. Conceptual science First, we must first introduce two concepts: crystalline and amorphous. A crystal body is a solid in which ions, ion groups or atoms of chemical elements constituting a mineral are repeatedly arranged according to a certain rule. The most typical is crystal. The original crystal hole can better reflect his composition. The crystal body is divided into single crystal and polycrystalline. Crystal, red, sapphire and many other gemstones are single crystals, and we are more familiar with polycrystals, such as Hetian jade and jade. Of course, the agate we said above is also this polycrystal. Quartzite is crystalline. It is generally said that the texture is coarse and visible to the naked eye. Typical quartzite jade has Huanglongyu, Donglingyu, Afghan jade, Jingbaiyu and so on. The chalcedony and agate are both cryptocrystalline, and the cryptocrystals indicate that the texture is fine and the particles are basically invisible to the naked eye. Finally, there is also a kind of wood stone, which is the so-called tiger eye stone and eagle eye stone. They are formed by the special geological silicification of ancient plants. Finally, amorphous: natural glass, opal. Natural glass includes the obsidian family. The most surprising thing may be Opal, this product should not be silicon dioxide! ! This family gap is too big! Definitely not a biological one! ! ! However, it turns out that Opal is made up of closely packed silica spheres, which are filled with adsorbed water and interstitial water, thus forming a beautiful color changing effect. At this time, do you think that the turtle, the grandson of silica, is contracting half of the gem world? This family is really not worrying! Finally, I would like to summarize a mouthful: single crystal is crystal; polycrystalline is quartz, crystallized Huanglong jade, cryptocrystalline agate, colloidal water is opal, gelatinization dehydration is agate.
