High Carbon Silicon Oxidation Resistance
As a special material, high carbon silicon has strong oxidation resistance. This is because the chemical composition and physical structure of high-carbon silicon make it resistant to oxidation. In this paper, the reasons for the oxidation resistance of high carbon silicon will be discussed from various aspects.

Description
High carbon silicon is an alloy material composed of silicon and carbon, in which the content of silicon is usually more than 70%, the content of carbon is between 15% and 30%. Through this chemical composition, high-carbon silicon has the following antioxidant properties:
(1) The silicon oxide SiO2 has high stability, can form a layer of dense SiO2 protective film, prevent the erosion of oxidation. The formation of this protective film can significantly improve the oxidation resistance of high-carbon silicon. For example, in high temperature oxidation environments, SiO2 films in high carbon silicon prevent further penetration of oxygen molecules and thus prevent oxidation loss of high carbon silicon.
(2) Carbon oxide CO has high reducibility, can react with oxygen to form carbon dioxide, avoid the continuation of oxidation reaction. For example, in high-temperature oxidation environments, the carbon in high-carbon silicon can act as a reducing agent, reducing the oxide to the original element, thus preventing further erosion by oxygen.
Specification
| High carbon silicon | Si | C | Al | S |
| ≥ | ≥ | ≤ | ≤ | |
| Si65C15 | 65 | 15 | 3 | 0.1 |
| Si60C10 | 60 | 10 | 3 | 0.1 |
In addition to the chemical composition, the physical structure of high-carbon silicon is also an important reason for its antioxidant properties. High-carbon silicon has the following physical structural characteristics:
(1) High-carbon silicon usually has high hardness and strength, and can maintain good physical stability under high temperature environment. In high temperature oxidation environment, the hardness and strength of high carbon silicon can help it resist the erosion of oxidation, thus maintaining its oxidation resistance.
(2) High-carbon silicon is very crystalline and has a good grain boundary structure. This crystallinity prevents the diffusion of oxidation at grain boundaries and thus maintains the oxidation resistance of high-carbon silicon.
