Карбид кремния против кремния: Подробное сравнение этих двух материалов

Silicon or карбид кремния (SiC) are the most commonly used in semiconductor and electronic devices industries.

Even though they have the same element, Silicon, in their name, they have different characteristics on most issues.

This article dives into the fascinating realm of silicon and silicon carbide, examining their properties, applications, and their growing role in the emergence of electronics and beyond.

SiC used in semiconductor

Understanding Silicon Carbide

SiC is one of the strongest materials known to man and comprises the elements Silicon (Si) and carbon (C). This grit, also known as “carborundum,” has exceptional characteristics, such as high hardness, excellent thermal conductivity, and abrasive resistance.

The remarkable properties of silicon carbide give it a vital role in many industries, like electronics, abrasives, power devices, and other emerging sectors.

Understanding Silicon

On the opposite end of the spectrum, Silicon (Si) plays a vital role in semiconductors. Being a Carbon family member, Silicon possesses the best semiconductor features, becoming the main pillar of the electronics industry.

Silicon powers electronic devices under specific conditions and serves as the basis for the reliable production of semiconductors. Integrated circuits have defined it as the essential element in the innovative process.

Difference Between Silicon Carbide & Silicon

Crystalline Structures

The structure of silicon carbide is more intricate, and its atoms form either a hexagonal or rhombohedral arrangement. This complexity is supplemented by its amazing hardness, thermal conductivity, and resistance to severe conditions, which makes it even better.

Silicon has a more simple crystal structure and forms a diamond cubic pattern. Such structure is the key to its semiconductive properties, making Silicon the ideal material for this application.

Physical and Mechanical Properties

The SiC is reputed for its strength, which has the exceptional properties of thermal conductivity, a high melting point, and great resistance to chemical and thermal wear. These qualities make it ideally fit for applications that require hardness and durability, including cutting, grinding, and heat-resistant electronic devices.

Silicon has properties that are best suited for semiconductor functions, providing stability, reliability, and seamless integration into electronic devices. Although not as tough as silicon carbide, it is very useful in the production of transistors, diodes, and integrated circuits due to its properties.


SiC is used in all types of high-power electronics, electric vehicles, renewable energy systems, and even in harsh circumstances. Its durability and thermal conductivity make it suitable for critical applications such as where traditional materials could fail.

Silicon is most commonly used in electronics. These semiconducting properties place it as a central block in semiconductor manufacturing, where it is used in various ways, such as the production of integrated circuits, solar cells, and microelectronics.


SiC is known to have superior thermal conductivity compared to Si. Heat dissipation, which is regarded as one of the basic properties of SiC, is crucial in cases where a heat protector is needed for high-power electric components as well as tooling and die-casting environments where high temperatures are expected.

While Silicon has decent thermal conductivity, it is not as good as silicon carbide for heat dissipation.

Environmental Resistance

The SiC crystalline structure is inherently immune to both chemical and thermal erosion, which makes it very resilient in extreme environments.

The resistance level of Silicon is not equivalent to that of silicon carbide. Its integrity is affected by the harshness of the environment.

Similarities Between Silicon and Silicon Carbide

The similarities between Silicon Carbide (SiC) and Silicon (Si) are important in their electronic and optical properties.

Compared to each other, SiC and Si are extremely unique in other areas in terms of their properties, but they have similar qualities which are significant in their application in many industries. Let’s explore the similarities in properties, applications, benefits, and more.

Common Element

Both materials possess Silicon as their key component, which is a very popular element due to the fact that it boasts various peculiar characteristics. The shared element based on a Silicon is one of the reasons which they are commonly used in electronics and other industries.

Crystalline Nature

Silicon crystalline, as well as SiC, have the structure of solid crystals. However, the latter has a more complicated shape than the previous one. SCS has a hexagonal or rhombohedral orthogonal structure, and SIS has a cubic one, like a diamond.


Both of them have thermal conductivity, though not to the same extent.

Semiconductor Properties

In addition, the two elements possess semiconducting properties that make them widely used in electronics.

Silicon leads the way in the area of semiconductors, and silicon carbide is known for its semiconducting properties for high-power electronics and the military.

Engineering Advancements

The SiC and Si technology has undergone a major shift toward science and engineering.

In the area of electronics, the impact of Silicon is unrivalled, and it has produced overwhelming progress in microelectronics and information technology.

Silicon carbide, being one of the best materials, has been used in edge high-power electronics, electric vehicles, and power systems based on its remarkable features.

Contribution to Clean Energy

Similarly, both issues have “green” energy-related solutions. Silicon is essential in solar cells because it transforms the sun into electrical energy.

Silicon carbide is a crucial element in power electronics yielding higher efficiency, thus providing a way for the interdigitation of clean energy forms such as electric vehicles and renewable power systems.

Continuous Research and Development

Research and development are being done for both types of material in parallel so that new uses can be discovered and their properties can be enhanced further.

Why SiC Is The Right Choice?

The applications of the areas of the industry are mainly carried out by silicon carbide (SiC) which outperforms Silicon (Si) in the most important functionalities.

The great hardness and wear resistance of SiC is unparalleled in cutting tools and abrasive materials where very high wear resistance is indispensable.

Also, SiC’s excellent thermal conductivity, capable of resisting both chemical and thermal wear, is the best for industries that require materials which perform well at high temperatures.

Also, SiC in specialized high-power electronics is the intermediary in the progress of electric vehicles and renewable energy systems. Although Silicon is a companion material for existing electronics, the intrinsic superiority of silicon carbide lets it cater to advanced applications for different industries.
