Magnesite, MgCO3, Magnesite is derived from the Greek city of Magnesia, and its name is Magnesite, which is internationally recognized. The Chinese did not transliterate, but it was translated into magnesite based on the rhombohedral crystal of the trigonal system and the MgCO3 component, which is scientific and smooth.
The high-quality magnesite around the world has a coarse crystal structure, which is called macrocrystalline magnesite according to petrological terms. In contrast, finely crystallized magnesite was once called cryptocrystalline magnesite, cryptocrystalline magnesite. The term Cryptocrystalline is a petrological term, which is defined as follows:
"The small components that are indistinguishable to the naked eye are called non-crystallized, aphanite, and its structure is called non-crystallized structure. Some non-crystallized rocks can be tested for glass phase under a microscope; while some are fully crystalline. If a single component in such rocks can be identified by a microscope, the structure is called microcrystalline, microcrystlline; if it is too fine, and cannot be identified under a high-magnification microscope, it is called cryptocrystalline. Some The material was homogeneous and light, but it was confirmed to be crystalline when tested by XRD."
