Black zirconia ceramic solid rod high accuracy precision finishing Industrial electrical structural parts
product name:Black zirconia ceramic solid rod
model:HY-YH03
Product description:
Zirconia is widely used and has a broad market. The specific applications include solid fuel cells, automotive exhaust treatment, dental materials, ceramic cutting tools, and zirconia ceramic optical fiber inserts. With the approaching of the 5G era of mobile phones, zirconia ceramics have become a hot spot in the industry again because of their warm and moist feel, scratch resistance, wear resistance, no signal shielding, excellent heat dissipation performance and other characteristics. The zirconia ceramic mobile phone backplane industry has risen rapidly.
Zirconia ceramics can be polished and beautiful in appearance, and the cost is low. It is an excellent wearable material and has been widely used in smart wear in recent years. Zirconia ceramics have high hardness, high wear resistance, good high temperature thermal stability and thermal shock resistance. With the development of zirconia ceramics, its application field has expanded from the field of refractory materials in the past to the field of structural ceramics, bioceramics and electronic functional ceramics. It also has active applications in high-tech fields such as aerospace and nuclear industry.
