FAQ
Comparison of the differences between vacuum graphite furnace and vacuum graphite carbon tube furnace
-
Q:What are the differences in the core heating components?
A:Both use graphite as the heating element, but Vacuum Graphite Furnace use graphite rods/plates for heating, while vacuum graphite carbon tube furnaces use tubular graphite (graphite carbon tubes) for heating, resulting in a more concentrated heat field.
-
Q:Does temperature uniformity vary depending on the size of the workpiece being used?
A:Vacuum graphite products have a wide temperature range and a large chamber volume, making them suitable for large workpieces. Graphite carbon tube products have a concentrated temperature within the carbon tubes, making them suitable for small, precision parts.
-
Q:What are the main application areas of vacuum graphite furnaces and vacuum graphite carbon tube furnaces?
A:Graphite furnaces are suitable for large-volume processing of large materials (such as ceramic sintering). Graphite carbon tube furnaces are suitable for small-volume, high-precision processing (such as inorganic non-metallicmaterials).
