SINTYRON Ceramic Pyrolytic Boron Nitride Pbn Ring

Product Overview

Our Pyrolytic Boron Nitride Ring (PBN Ring) is a high-performance advanced ceramic component manufactured

by chemical vapor deposition (CVD) process. It is made of high-purity boron nitride raw materials, with a structure

similar to graphite, presenting a white, non-toxic and dense surface. With excellent high-temperature resistance,

chemical inertness, electrical insulation and thermal conductivity, it is widely used in semiconductor, aerospace,

metallurgy and laboratory high-precision high-temperature scenarios. The product has obvious anisotropy in

mechanical,thermal and electrical properties, which can meet the strict requirements of various high-end industrial

processes for materials.

Performance Advantages

✔ Ultra-High Purity & Dense Surface:

Purity up to 99.99%, no pores, good air tightness, non-toxic and easy to process, which can avoid pollution to the

processed materials and ensure the purity of products in high-precision scenarios.

✔ Excellent High-Temperature Stability:

It can maintain stable structure and mechanical strength in the temperature range of -270℃ to 2200℃, and its strength

reaches the maximum at 2200℃, which is suitable for various extreme high-temperature working conditions.

✔ Strong Chemical Inertness:

It is resistant to acids, alkalis, salts and organic reagents, and does not wet or react with most molten metals and

semiconductors at high temperatures, ensuring the stability of the process.

✔ Superior Electrical & Thermal Performance:

High volume resistivity, high dielectric strength and low dielectric constant, with good microwave and infrared transmission

performance; excellent thermal shock resistance, low thermal expansion coefficient and anisotropic thermal conductivity,

which can meet the heat dissipation and insulation requirements of high-end equipment.

✔ Customizable & Versatile:

We can provide customized production according to the customer's required inner diameter, outer diameter, thickness and

surface finish, and it is widely applicable to semiconductor, aerospace, laboratory and other fields.
