High Durability Advanced Coating Graphite Crucible

Graphite boat used in PECVD of solar cell production line

The production of solar cells requires six major processes: texturing, diffusion, etching, coating, screen printing and sintering. In the manufacturing of solar cells, the PECVD tube coating process uses a graphite boat as the working body. The coating process uses plasma enhanced chemical vapor deposition to deposit a silicon nitride film on the front of the silicon wafer to reduce sunlight reflection and the surface of the silicon wafer.

Features of our PECVD graphite boat:
1). Adopted to eliminate the "color lenses " technology , to make sure without "coloe lenses"  during the long-term process.
2). Made of the imported graphite material with high purity ,low impurity content and high strength.
3). Using the 99.9% ceramic for the ceramic assembly with strong corrosion resistant performance and brust proof.
4). Using the precision processing equipment to ensure the accuracy of each parts.
