Description

The microstructure of ferrosilicon zirconium alloy is mainly composed of iron base phase, silicon base phase and zirconium base phase. Among them, iron base phase is the main structural component, silicon base phase and zirconium base phase are the added elements. The combined action of these three phases determines the properties of ferrosilicone-zirconium alloys.
The iron base phase is the main component of the ferrosilicone-zirconium alloy and occupies most of the volume of the alloy. The iron base phase has good thermal stability, its crystal structure is stable, few lattice defects, high crystallinity, can effectively resist thermal expansion and deformation in high temperature environment, so as to ensure the stability of the alloy.
The addition of silicon phase and zirconium phase can improve the thermal stability of the alloy. The silica-based phase has high melting point and thermal stability, which can effectively inhibit the grain growth and grain boundary migration of the alloy, so as to improve the resistance to high temperature creep and oxidation.

Zirconium base phase has high oxidation resistance and corrosion resistance, which can effectively slow down the oxidation rate and corrosion rate of the alloy at high temperature, thus prolongating the service life of the alloy.
The interaction of the three phases makes the ferrosilicone-zirconium alloy have high thermal stability.

Good Thermal Stability Ferro Silicon Zirconium

Example: ferrosilicon zirconium alloy as high temperature thermoelectric material application.

As an important high temperature material, ferrosilicon zirconium alloy is widely used in high temperature thermoelectric conversion devices. Thermoelectric conversion device is a kind of device that converts heat energy into electric energy. It can convert high temperature heat energy into usable electric energy and has a wide application prospect.
The thermal stability of ferrosilicone-zirconium alloy based thermoelectric conversion materials is one of the important reasons for their application in high temperature environment. For example, thermoelectric conversion devices need to be able to work normally in high temperature environment, and ferrosilicone-zirconium alloy has good high temperature resistance, can maintain its thermoelectric and mechanical properties in high temperature environment, so as to ensure the normal operation of the thermoelectric conversion devices. In addition, the oxidation resistance and corrosion resistance of ferrosilicone-zirconium alloy are also important factors for its application in high temperature thermoelectric conversion devices.
