What is Si3N4 reaction bonded SiC?

Si3N4 bonded SiC is a new type refractory material, the applying temperature is 1400 ℃, it has better thermal stability, thermal shock, 

which is better than plain refractory material and recrystallization SiC.

Introduction of Si3N4 tube

Si3N4, or silicon nitride, is a ceramic material that is frequently utilized in the production of protective tubes(Si3N4 silicon nitride protection tube), 

which is an inorganic material ceramic and does not shrink during sintering. These tubes can be used to protect sensors, probes, or other equipment

 from harm in harsh chemical and high-temperature conditions.

Reaction bonded silicon nitride tube properties

The Si3N4 tubes are well-regarded for their exceptional thermal stability, high strength, and resistance to corrosion and wear. 

They can be used in a wide range of industries, including aerospace, automotive, and chemical processing.

Thermal stability

The exceptional thermal stability of Si3N4 is due to its high melting point of 1,800°C, which makes it a suitable material for use

 in extremely high-temperature environments.

High strength

Its high strength and toughness enable it to withstand mechanical stresses and shocks, which make it suitable for use in harsh

 environments.

Resistance to corrosion and wear

Silicon nitride is corrosion and wear resistant. Silicon nitride is highly chemically stable, it does not react with other inorganic acids

 except hydrofluoric acid,, as well as its resistance to abrasion, makes it a suitable material for use in chemical processing plants 

and other harsh environments.

Thermal shock resistance

It is also resistant to hot and cold shocks, heats up to 1000 degrees or more in air, cools quickly, and then heats up quickly without

 breaking.

Technical data of Si3N4 silicon nitride protection tube

The following table is a comparison of Si3N4 parameters made by two different processes.

Applications

The series of products are widely used for measuring temperature in the fields of ceramic, metallurgy, chemical industry, etc.

In conclusion, reaction bonded silicon nitride tube(Si3N4 tube) are a reliable and durable solution for safeguarding equipment

 in harsh environments, The service life can last for many years with regular maintenance.

They provide high thermal stability, high strength, and resistance to corrosion and wear, excellent protection, impermeability and 

excellent precision, making them a popular choice for industries that operate in demanding conditions.
