1. Introduction

Modern production is increasingly faced with the need to use materials, able to confidently withstand extreme conditions: high temperatures, aggressive chemical environments, abrasion, high pressure and dynamic load. In such areas, nozzles are key components, determining the efficiency of the technological process, durability of the equipment and stability of the quality of the final product.

Ceramic zirconia nozzle (ZrO₂) from Sanxin New Materials is a custom designed product, custom-made with high precision and adaptation to specific client tasks. Thanks to the unique properties of ZrO₂ particles and advanced production technologies, such nozzles are superior to traditional metal ones, plastic and standard ceramic analogues.

2. What is Zirconia Ceramic Nozzle (ZrO₂)?

Zirconium dioxide (ZrO₂) is an engineering ceramic, exhibiting exceptional hardness, crack resistance, chemical inertness and high thermal stability. Unlike other technical ceramics, which may be fragile, ZrO₂ is stabilized by adding yttrium oxide (AND₂OR₃), which creates a material with high crack resistance, resistance to thermal shocks and excellent wear resistance.

Ceramic zirconia nozzle is a specialized component, custom-made for a specific application: form, hole diameter, profile, wall thickness, connections, fasteners, etc.. d. This approach allows you to optimize the operation of installation components and extend their service life.

3. Key benefits of ZrO₂ nozzles

Zirconium ceramic nozzles offer a number of unique advantages, ensuring their high competitiveness:

3.1 High hardness and wear resistance

ZrO₂ has a hardness of about 1200–1300 HV, significantly exceeding the hardness of most metals and oxide ceramics. This ensures resistance to abrasive wear and minimal material loss during operation..

3.2 Excellent crack resistance

Unlike many ceramics, stabilized zirconium dioxide has the ability to soften the development of cracks due to transformative hardening. This is critical for components, working under dynamic loads.

3.3 Chemical inertness

ZrO₂ ceramic nozzles are acid resistant, alkalis, salts and aggressive chemical media, which allows them to be used in many technological processes, where metals quickly deteriorate.

3.4 High temperature resistance

The material maintains mechanical and structural stability at temperatures up to 1000–1200 °C and above, depending on modification, making it ideal for heat treatment, spraying coatings, plasma and laser processing.

3.5 Low thermal conductivity

This allows you to reduce heat losses between the process zone and the environment, improve safety and reduce stress on adjacent equipment components.

3.6 Electrical insulating properties

ZrO₂ is an excellent dielectric, what makes such nozzles applicable in electrical engineering and microelectronics, where protection against leakage currents and induced voltages is required.

4. Application of ceramic nozzles made of ZrO₂

Zirconium dioxide ceramic nozzle is in demand in various industries:

4.1 Sandblasting

Nozzles are used to direct the impact of abrasive mixtures on the surface being treated, where high wear resistance and flow precision are required.

4.2 Plasma spraying

In installations for plasma surfacing, nozzles ensure stable formation of a plasma jet at high temperatures.

4.3 Gas and liquid atomization

Nozzles are used to form an even and controlled spray of the working substance, what is critical in chemical reactors, furnaces and processing lines.

4.4 Chemical industry
