Is a silicon core a semiconductor?
Thread Content
Is a silicon core a semiconductor? How does its resistance change as the temperature rises? Thank you! Also, is it better for the silicon core resistance to be high or low when starting the furnace under high pressure?»
The silicon core is a semiconductor, and its resistivity decreases as the temperature rises
Is it advantageous or merely slightly advantageous to start the furnace under high pressure? What is the typical temperature in the furnace?
As mentioned on the 2nd floor, silicon cores are semiconductors; their resistivity decreases as the temperature rises, and this is also a characteristic of semiconductors. At startup, those with a lower resistivity are certainly more likely to break down. Silicon cores with thick diameters still have benefits for starting up the furnace.
