Silicon Carbide Plates

Silicon carbide plates are often used in various industrial and engineering applications due to their hardness, strength and durability. This guide will provide you with all the information you need to know about silicon carbide plates and their uses, from the materials they're made of to how they can be implemented in various industries.

What is Silicon Carbide?

Silicon carbide (SiC) is a man-made, black crystal composed of carbon and silicon atoms. It is one of the most common abrasives used due to its Mohs hardness rating of 9.5, which makes it capable of efficiently cutting through hard materials like metals, plastics or ceramics. Its high level of thermal conductivity also make it a great material for heat sinks and other electronics applications.

Benefits of Using Silicon Carbide Plates

Silicon carbide plates have many beneficial properties that make them an ideal material for a variety of applications. These benefits include their ability to resist high temperatures, maintain low thermal expansion rates and have excellent thermal conductivity.

It features 99.5%, 98%, and 88% purity levels and is primarily composed of an elemental silicon-carbon compound. As a result, it has several advantageous properties such as a high thermal conductivity, excellent chemical and oxidation resistance, as well as a high strength-to-weight ratio enabling its use in plates that are lighter in weight than other materials.

These plates are characterized by their high porosity, which should be less than 15%, as well as by their thickness, which is typically around 2.5 mm or 0.1 inches. Silicon carbide plates have an excellent flexural strength of up to 400 MPa, making them incredibly resilient and durable in a wide range of applications. They are known for their strength and stability, as they have a compressive strength of more than 300 MPa, 2200 MPa and 2100MPa.

Silicon Carbide is an extremely durable and heat-resistant material often used in the production of industrial and commercial plates. Its thermal expansion coefficient is 4.6 when exposed to temperatures over 1200°C, while at temperatures of 500°C or lower its coefficient drops to 4.0 or 4.4 respectively. Silicon carbide plates have excellent thermal conductivity in the range of 35~36 W/m.K at 110 degrees Celsius and 65 W/m.K.

Silicon carbide plates are resistant to high temperatures and have a high resistance to damage, making them ideal for use in a variety of applications. They can be used for their thermal conductivity and mechanical strength, making them ideal for use in the automotive, aerospace, and energy industries. Furthermore, they are non-toxic and inert, meaning they are safe to use in a wide range of environments.

In addition, they are highly chemical resistant and less prone to wear than other materials. This makes silicon carbide plates an ideal choice for use in industrial processes where frequent cleaning and exposure to harsh chemicals is required.

Applications Where Silicon Carbide Plates are Used

Silicon carbide plates are widely used in various industries and applications due to their excellent properties. They are most commonly used in abrasive cut-off wheels or grinding wheels, refractory materials, automotive components, bearing parts and heat exchanger components due to their heat resistance. Additionally, they are also used for semiconductor substrates, electrical insulation plates and wear resistant components such as liners for ball mills.

Manufacturing Processes for Silicon Carbide Plates

Silicon carbide plates are manufactured through a variety of processes, including hot pressing, hot isostatic pressing (HIP), and reaction-bonded sintering. Hot press process involve the formation of billets which are then heated up to 2200°C in order to form a homogenous green body which is then further processed. On the other hand, HIP or isostatic process involves the heating of green bodies at 1500°C under extreme pressure. Finally, RBS process involves the use of powders and a binder as well as high temperatures for sintering in order to produce finished pieces.

Silicon carbide (SiC) is a hard, strong material with highly desirable properties for use in industrial applications. It is made up of silicon and carbon. SiC can be manufactured using several different methods including recrystallization, sintering, and reaction bonding, which all result in a plate-like form of SiC that can be used in industrial processes.

Choosing the Right Silicon Carbide Plate

When it comes to choosing the right silicon carbide plate for your application requirements, you must consider several factors. First, the chemical or physical properties of your material should be taken into account such as thermal conductivity, hardness, and maximum operating temperature. The size and thickness of the plates must also be taken into consideration. Additionally, it is also important to consider factors such as cost effectiveness, reliability, and availability before purchasing a plate suitable for your purposes.
