What is Pressuerless sintered silicon carbide (PSSIC) ?
Pressuerless sintered silicon carbide (PSSIC) is a high-performance ceramic material with a wide range of
characteristics and applications. Here is a detailed introduction to
pressuerless sintered silicon carbide:
Definition and Characteristics:
Pressuerless sintered silicon carbide (PSSIC)
is a new type of ceramic material composed primarily of silicon carbide
and a certain amount of additives. It is produced through specific
processes such as forming, drying, and heat treatment.
Compared
to traditional pressure sintered silicon carbide, pressuerless sintered
silicon carbide does not require the application of high pressure
during the preparation process, thus avoiding sintering issues caused by
material unevenness.
Pressuerless
sintered silicon carbide has a higher sintering temperature and better
crystallization properties, resulting in excellent physical performance
including high temperature stability, high hardness, high strength, and
corrosion resistance.
Preparation Process:
The preparation of pressuerless sintered silicon carbide (PSSIC) involves mixing silicon carbide powder with additives, forming, and then sintering at high temperatures.
The sintering process can be solid-phase sintering or liquid-phase sintering, depending on the additive and sintering conditions.
Performance Advantages:
Pressuerless sintered silicon carbide (PSSIC)
maintains stable strength performance at high temperatures, exhibiting
high tensile strength, compressive strength, and bending strength.
It
also has good corrosion resistance, allowing it to be used in various
harsh environments, including acidic, alkaline, high-temperature, and
high-pressure conditions.
The forming process is simple and easy to control, enabling the production of large-sized and complex-shaped products.
Application Fields:
Semiconductor
Industry: Pressuerless sintered silicon carbide can be used as
substrate materials and heat sinks for semiconductor equipment due to
its high-temperature stability, excellent wear resistance, and chemical
inertness.
Power Industry: It can be used as structural materials for high-temperature heat exchangers and high-temperature combustors.
Machinery
Industry: Used in the manufacture of mechanical components under high
temperature and pressure, such as turbine blades, bearings, seals, etc.
Aerospace
Industry: Used in the manufacture of high-temperature structural
components and thermal protection materials, such as engine nozzles,
high-temperature thermal protection plates, etc.
Chemical
Industry: Used in the manufacture of chemical reactors, furnace pads,
and other equipment that requires high temperature resistance and corrosion resistance.
In summary, pressuerless sintered silicon carbide (PSSIC) plays an important role in various industries due to its excellent physical properties and broad application prospects.
