Key features

High electrical resistivity supports insulation between high-temperature electrodes and furnace components.

Low thermal expansion helps maintain dimensional relationships at mating surfaces.

Suitable for electrode isolation, spacing control, flange fitting, and structural positioning.

Good chemical stability supports high-temperature furnace service.

Available as full, split, slotted, and perforated rings.

Stepped and multi-layer rings can be produced for complex assemblies.

Low density makes installation and replacement easier inside high-temperature equipment.

This category is for pure-BN insulation rings, not composite-BN continuous-casting separation rings.
