Introduction
The Polycrystalline Rod is often used as electric heating elements in high temperature vacuum furnaces. The maximum working temperature can reach 3000°C. Secondly, it is easy to oxidize at high temperature and can only be used in neutral or reducing atmosphere and in vacuum furnaces. What's more, because of its small coefficient of thermal expansion and large thermal conductivity, it is easier to process than other products, resistant to high temperature, extreme cold and extreme heat, and has the characteristics of good and cheap price. Finally, if you are interested in our products, please contact and communicate with us in time.
Product Nature:
Gray metallic luster, brittle at room temperature, easy to break when cutting. When heated to 800℃, polycrystalline rod has ductility, and shows obvious deformation at 1300℃. It is active at high temperature and can interact with almost any material. With semi-conductance, it is an excellent semiconductor material.
Feature
The Polycrystalline Rod have the characteristic of corrosion resistance. Except for hydrofluoric acid, our products hardly react chemically with other acids, especially the chemical stability under high temperature, which is unmatched by any other engineering materials. What's more critical is that we have good thermal stability. It has a very small coefficient of thermal expansion and can withstand drastic temperature changes. Finally, our products have a strong practical value.
Product application:
In the electronic industry is widely used in the manufacture of refrigerators, computers and other basic materials. Including now popular new energy vehicles also need to use polysilicon, a bright future.
Production process:
It is obtained by chlorination of dried silicon powder and dried hydrogen chloride gas under certain conditions, and then through condensation, distillation, reduction and other processes.
