Graphite Support Pedestal for Quartz Crucible Ingot Furnace
Product Overview
Our precision-machined graphite support pedestals (also called crucible supports or susceptors) are designed to hold quartz crucibles in polycrystalline silicon ingot casting furnaces. Made from high-density isostatic graphite, these support pedestals provide robust structural support, excellent thermal conductivity, and long service life for high-temperature ingot growth processes at up to 1600°C.
We manufacture complete graphite crucible support assemblies for all major ingot furnace brands including G5, G6, and G7 standard furnace configurations. Our pedestals are precision machined for perfect fit with the quartz crucible and furnace bottom heater assembly, ensuring reliable performance throughout the ingot growth cycle.

FAQ
Q: What furnace models do your support pedestals fit?
A: We manufacture graphite support pedestals for all major polycrystalline silicon ingot casting furnace models including G5, G6, and G7 furnaces from leading brands. Please specify your furnace model for accurate matching.
Q: How often should the graphite support pedestal be replaced?
A: Typical replacement interval is 12-24 months or 50-100 ingot cycles depending on operating conditions. The pedestal should be inspected during scheduled furnace maintenance for cracks, deformation, and crucible seating flatness.
Q: Can you provide complete bottom hot zone assemblies?
A: Yes, we offer complete bottom heater assemblies including graphite support pedestal, bottom heater elements, insulation, and mounting hardware. Our assemblies are designed as direct replacements for your specific furnace model.
