MTI corporation provides the high quality Alumina (Al₂O₃ ) foam block for high temperature tubing furnaces in universities, companies, and national labs. It comes with the specifications as the following:

• Max. working temperature:  < 1700ºC
• Diameter:  90 mm (3.54") ± 2mm (0.08")
• Length:     65 mm (2.56") ± 2mm (0.08")
• The block must be put in the place between sample and flange..
• Fit MTI's OTF-1200X-4 Quartz Tube Furnace, and GSL1700-100X Bench-top High Temperature Tubing Vacuum Furnace.

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.
