Zirconia ceramic sealing rings

Thermal Shock Resistance

Thermal shock resistance, also known as thermal stability or thermal impact resistance, refers to the ability of a material to withstand damage when subjected to rapid temperature changes. Specifically, when a material experiences drastic temperature changes in a very short time, it develops internal thermal stress, which can lead to cracking, delamination, or fracture. Zirconia ceramics, however, demonstrate outstanding thermal shock resistance, mitigating the formation of cracks and damage in equipment due to thermal shock.

Corrosion Resistance

In industrial settings, exposure to corrosive mediums such as acidic or alkaline solutions, and corrosive gases is common. Zirconia ceramics exhibit excellent corrosion resistance, allowing them to withstand prolonged exposure to harsh environments like strong acids and bases without significant corrosion damage.

High-Temperature Stability

At high temperatures, materials may undergo various chemical reactions such as oxidation, reduction, and decomposition, along with physical changes such as phase transitions and lattice structure alterations, leading to loss of stability, deformation, or embrittlement. Zirconia ceramics possess excellent high-temperature stability, maintaining stable physical and mechanical properties over extended periods in high-temperature environments.

Wear Resistance

Components made from traditional materials often experience severe wear under conditions of high-speed rotation and heavy loads. Zirconia ceramics offer exceptional wear resistance, maintaining stable performance in high-friction and high-wear environments.

Chemical Industry

1. Sealing Applications

In chemical production processes, a large number of seals are required to ensure equipment sealing and prevent media leakage. Corrosion-resistant and high-temperature-resistant sealing gaskets made of zirconia ceramics can withstand the working conditions of high pressure and high temperature, ensuring safe operation of equipment.

2. Valves and Piping Systems

Valves and piping components in chemical equipment endure the flow of media and pressure, requiring excellent corrosion resistance and high-temperature resistance. Valve and piping components made of zirconia ceramics can operate stably for long periods in corrosive media and high-temperature conditions, reducing equipment maintenance costs and downtime.
