black zirconium oxide Zirconia Ceramic Block brick
Reputation depends on quality, quality comes from Hard!
Zirocnia Ceramics:
Chemical composition: ZrSiO4, which can contain trace amounts of Mn, Fe, Ca and radial elements U, Th, and the like. The high-type black zircon has a hardness of 7-7.5, and the low-type zircon has a hardness of 6, both of which are brittle, and the corners are often broken. High-type zircon has a specific gravity of 4.6-4.8, and low-type zircon has a specific gravity of 3.9-4.2.
The dark color cubic zirconia is obtained by subjecting the colorless synthetic cubic zirconia crystal to a vacuum of 2000 degrees for reduction treatment. The principle is that oxygen in ZrO2 is lost, causing a large number of crystal defects, which are all black and absorbed by visible light. There are two ways to process black zirconium: one is to directly treat the finished gemstone, and the other is to cut the raw material into gemstone after the raw material. Black zirconium is used in large amounts However, if black zirconium is used for waxing, it may change color, and a small test should be done first.
use
Black has a symbolic meaning, representing solemnity and sacredness. Black zircon is used by the jewelry design industry for inlaid jewelry products. It has high artistic value and highlights the style of wearing jewelry.
