Sapphire flat washer HPLC Deep Sea Sensors Vacuum Chambers

Product Description:

Our sapphire flat washers are manufactured from high-purity single crystal aluminum oxide (99.995%), offering exceptional mechanical strength, thermal stability, and optical performance. With a Mohs hardness of 9, which provides outstanding resistance to scratching, abrasion, and chemical corrosion, making them ideal for demanding industrial and scientific applications.

One of the key advantages of sapphire flat washers is their excellent thermal resistance. They can operate continuously at temperatures exceeding 2000 °C and maintain structural integrity even in harsh thermal cycling conditions. In addition, sapphire exhibits superior chemical inertness, resisting attack from most acids, alkalis, and corrosive gases, which ensures long service life in aggressive environments.

High dielectric strength ensures zero electrical interference, even in ultra-thin profiles, making them ideal for high voltage and ultra-high vaccum isolation.

Key Features:

Thermal Resistance:Withstands temperatures above 2000 °C, maintaining stability in extreme heat(continuous use around 1500°C and thermal cycling environments.

Hardness & Durability: Mohs hardness of 9, offering outstanding resistance to scratches, wear, and mechanical damage.

Chemical Stability: Highly resistant to acids, alkalis, and corrosive gases, ensuring long service life in harsh chemical environments.

Fully Customizable Dimensions:Available in customized outer diameter, inner diameter, length, and surface finish touch to meet specific application requirements.

Applications:

1. Synthetic sapphire flat washers are essential in high-performance engineering due to their extreme hardness and chemical neutrality. First, in HPLC systems, they serve as high-pressure seats within pump heads, enduring over 10,000 psi while remaining inert to aggressive analytical solvents.

2. They are critical in aerospace sensors, where they act as mounting spacers in infrared targeting systems. In these environments, they must survive high-velocity friction, sand erosion, and extreme thermal shock without cracking.

3. They are indispensable in vacuum and cryogenic research. As non-outgassing insulators with high thermal conductivity at near-absolute zero, they are ideal for mounting sensitive components in quantum computers.
