"First, place the high-purity polysilicon in a quartz crucible, and heat it until it melts!" Zhou Jilong pressed the button on the machine, while Xiong Lao and Chai Lao watched the changes inside through the glass window.
"Lao Zhou, what's the temperature now?" Xiong Lao looked at the high-purity polysilicon in the quartz crucible, which had just started to change slightly, and then turned to Zhou Jilong.
"It just reached 1000 degrees Celsius. It hasn't reached the complete melting point yet; the temperature is still rising."
Soon, the temperature reached the melting point of high-purity polysilicon, which was 1420 degrees Celsius. The melting process accelerated noticeably, and in no time, the polysilicon in the quartz crucible had completely melted.
"We must be careful in making the crystal rod, especially when inserting it. We need to control the temperature as well!"
