Injection Carbon And Semi-coke

Semi-coke is a type of fuel and carbon-rich product that is produced through the slow carbonization of coal.

Silicon Carbide

Silicon carbide or SiC is a compound made from silicon and carbon. It is also known as carborundum.

Electrically Calcined Anthracite

Electrofused smokeless coal, commonly known as electric calcined anthracite, is a type of coal that is burned without producing smoke.

What is Silicon Carbide

Silicon carbide is a high-hardness ceramic material suitable for abrasives, refractory materials and semiconductor devices.

Product Features

High Wear Resistance
Silicon carbide utilizes high-purity α-SiC crystal material with a hardness of 9.5 on the Mohs scale, significantly extending the life of wear parts to 3-5 times that of ordinary cast steel.

Chemical Stability
It is non-reactive to acids, alkalis, and corrosive media, making it suitable for processing a variety of ores and chemical materials.

FAQ

Q: What is the thermal conductivity of silicon carbide?

A: Silicon carbide has high thermal conductivity and can dissipate heat quickly, contributing to the stable operation of electronic devices and high-temperature equipment.

Q: What is the chemical stability of this carbide?

A: This carbide is stable in acidic, alkaline, and oxidizing environments and is not easily corroded. It can be used in chemical reactors or highly corrosive environments.

Q: How should silicon carbide be stored?

A: Despite being the most widely used semiconductor in electronics, silicon is beginning to show some limitations, especially in high-power applications. A relevant factor in these applications is the bandgap, or energy gap, offered by the semiconductor. When the bandgap is high, the electronics it uses can be smaller, run faster, and more reliably. It can also operate at higher temperatures, voltages, and frequencies than other semiconductors. While silicon has a bandgap of around 1.12eV, silicon carbide has a nearly three times greater value of around 3.26eV.

Q: What is the role of this carbide in electronic devices?

A: This carbide can be used in high-voltage and high-frequency semiconductor devices.

Q: What is the role of this carbide in refractory materials?

A: Adding this carbide to refractory materials can improve high-temperature resistance, reduce the occurrence of thermal cracking, and enhance overall strength, making the material more stable in high-temperature environments.
