At present, the most regenerated crystals (that is, crystals) are produced, and a method called hydrothermal method is used to produce crystals. The basic principle of this method is to inject a large amount of blast furnace vats of about 2 floors. Water silicic acid", added silica.
Then, in the upper layer of the bottom layer, a high temperature of about 400 degrees Celsius is added, and the upper layer is slightly lower than the temperature of the lower layer by about 40 degrees, and the crystal nucleus attached to the crystallized regenerated crystal is suspended in the sputum (looks like a piece of 20 cm). The right and left meters, thin and thin, can be cut by the method in the future. Using the principle of heat convection, the high-temperature super-saturated raw material sputum flows from the bottom layer to the lower temperature upper layer, and the crystal slowly adheres to both sides of the crystal nucleus. .
Finally, a thick sheet of crystal is formed, and the crystal nucleus is sandwiched. After about two or three days, when crystallizing to a certain thickness, the crystal is extracted and cooled, and then the middle nucleus is sawn off, and the rest is crystal clear and uniform crystal.
Therefore, according to this principle, the temperature and pressure and the environment are strictly supervised throughout the operation, and cannot be easily changed, otherwise the entire step cannot be completed, so the color of the whole crystal is bound to be uniform, and the natural citrine is The color is shallow and deep, and there are clouds or ice cracks.
Labor can't be imitated so far, so this is the most worthy of our cherished place, which will be the wonderful thing of the universe.
