Low Mass Ceramic Composite (PBN / PG / PBN)

At Thermic Edge, we offer PG-PBN heaters for applications where fast temperature ramping is required in a reactive environment. A pyrolytic graphite (PG) element track is formed on a pyrolytic boron nitride substrate. The track is then covered in PBN to insulate and protect it. Standard heaters sizes are shown in the table below. All heaters are supplied with power leads and thermocouples and can be supplied with power supplies and controllers. These heaters can be supplied flange mounted or fitted to our heater stages.

Features

1400°C maximum temperature in vacuum
900°C maximum temperature in air
High vacuum, UHV and corrosive environments
Very fast ramp rate, with low mass
Very inert
PG element is encapsulated in PBN completely protected from deposition product
Sample can be placed directly onto heater ceramic element plate
Available in sizes up to 4” square or round
