  • Length:     75 mm ( 3.0") ± 2mm (0.08")

Application Note:

  • To prevent the dust-falling issues and ensure a cleaning process, it is suggested to apply a thin layer of alumina adhesive material on the surface of the foam block. Please click underline to order.
  • For direct delivery of precursor gasses over the heating zone, the customer may drill a hole in the alumina block for sticking a 1/4" O.D. quartz (<1200ºC) or alumina (<1700ºC) tube to deliver gas into the furnace tube center. Porous alumina block is very soft and it can be hand-drilled through easily.
