Manufacturers long-term supply of graphite thermal field and graphite parts
Common graphite heaters have three shapes, cylindrical, cup, and spiral. At present, the vast majority of heaters are cylindrical.
The heater is generally made of high-purity graphite with a carbon content higher than 99.9%; the wall thickness of the graphite bowl is generally 3 mm - 6 mm; after long-term practice, the effective length of the heater is 1.6 to 1.8 times the height of the quartz crucible.
