Product Description
In industrial production, the demand for wear-resistant materials has remained high, especially in industries such as steel, mining, ports, chemicals, thermal power, cement, etc., that have extremely high requirements for wear resistance. ZTA ceramics, as an advanced wear-resistant material, are gradually becoming the darling of these industries, providing a new idea and solution for solving equipment wear problems.
ZTA ceramics are zirconium oxide toughened alumina ceramics, which are high-performance ceramics made by compounding two ceramic materials, alumina (Al₂O₃) and zirconium oxide (ZrO₂), through a specific process. In many applications, it mainly appears in the form of ceramic pipes and ceramic linings, providing reliable wear protection for various industrial equipment, especially in the mining industry.

FAQ
Q1: How good is the wear resistance of ZTA ceramics? Can you
explain it with specific data?
A1: Under the same working conditions, the wear resistance of ZTA
ceramics is dozens of times higher than that of ordinary metal
materials. For example, in the coal pipe application of a steel
plant, the service life of ordinary steel pipes is only about 3
months, while the service life of ZTA ceramic pipes can reach more
than 3 years.
Q2: How high a temperature can ZTA ceramics withstand?
A2: The temperature is usually around 100℃~500℃. ZTA ceramics can
work stably, but if the temperature exceeds its limit, it may
affect its performance and service life, especially the glue-filled
filled will be shortened by high temperature.
Q3: The price of ZTA ceramics is relatively high. Is it worth
investing?
A3: Although the one-time investment cost of ZTA ceramics is high,
in the long run, the maintenance cost reduction brought by its long
service life is very significant. Take the mine chute lining as an
example. Ordinary rubber linings need to be replaced several times
a year, while ZTA ceramic linings can be used for more than 5
years. After comprehensive calculation, its use cost is much lower
than traditional materials.
Q4: Can ZTA ceramics be customized in various shapes and sizes?
A4: Customizable. We have advanced production technology and
equipment. We can customize ceramic pipes and liners of various
shapes and specifications according to the drawings provided by
customers or the actual equipment size to meet the personalized
needs of different equipment.
