First of all, we need to know PECVD (Plasma Enhanced Chemical Vapor Deposition). Plasma is the intensification of the thermal motion of material molecules. The collision between them will cause the...
Application and characteristics of graphite sagger crucible
Crucible can be used for intensity heating of a large number of crystals. Crucible can be divided into graphite crucible and quartz cruc...
Silicon carbide is a compound of Silicon and Carbon with chemical formula SiC. Today SiC coated graphite is widely used in high-temperature/high-voltage semiconductor electronics.

How to use graphite rotor correctly
1. Preheating before use: the graphite rotor shall be preheated at about 100mm above the liquid level for 5min ~ 10min before immersion in aluminum liquid to av...
The rising price of raw materials is the main driver of the recent price rise of graphite electrode products. the background of the national “carbon neutralization” target and the stric...
1. Acknowledgement before cleaning
1) When the PECVD graphite boat/carrier is used more than 100 to 150 times, the operator needs to check the coating condition in time. If there is an abnormal coa...
