Product Overview

Description

High quality Silicon Nitride tube/Silicon carbide bonded silicon nitride tube

Silicon Nitride is a fully dense, pressureless sintered ceramic specifically compounded to yield an amorphous intergranular phase. Pressureless sintering allows for net shape forming of complex components in a cost effective manner. This grade is isotropic with respect to engineering properties and offers excellent resistance to mechanical fatigue. PSO Si₃N₄ is useful for both large shaped, large cross-sectional structures as well as small, intricate components.

Features:

• Excellent thermal conductivity


• Excellent thermal shock resistance


• Low wetting by aluminum


• Available in a variety of formulations

Benefits:

• Longer life due to reduced dross build-up


• Coupling device reusable; simply attachment with another ceramic tube
