Polysilicon

The silicon element is very common on earth. A dedicated industry is transforming natural silicon oxides into a multi-crystalline and purified form of silicon called the “Polysilicon”.

Anticorrosion equipment

Firstly, the purification process requires the usage of corrosive fluids such as the hydrochloric acid. Mersen is providing fully adapted process equipments such as

• Our hydrochloric acid stripper

High temperature solutions

Siemens CVD process, as well as other production processes, requires solutions bearing high temperature conditions up to 1500°C. Mersen has developed dedicated solutions adapted to customer’s requirements.

Purity of raw material

• Our graphite consumables

Durability against aggressive atmosphere

• Our purified and coated specialties

Energy efficiency

• Our high temperature thermal insulation

Most of today’s electronic devices are built on silicon substrates.

The manufacturing process is highly corrosive and carried out at high temperatures.

Mersen provides:

• HCL sintaclor
• Graphite
