Poisson'S Ratio 0.25-0.3
Product Description:
Silicon Nitride Ceramics is a high-performance material that is
widely used in harsh and challenging environments due to its
superior strength, thermal stability, dielectric strength and
fracture toughness. This material has a bending strength of 750
MPa, a thermal expansion coefficient of 2 x 10-6/K, a dielectric
strength of 18-20 KV/mm, a fracture toughness of 7 MPa and a
hardness of HV0.5≥1700, which makes it an ideal solution for a
variety of industrial applications. It also features excellent
corrosion resistance, abrasion resistance, electrical insulation
and chemical stability. The SI3N4 ceramic ball is the most popular
form of silicon nitride ceramics and is often used in a wide range
of applications, ranging from cutting tools to bearings and valves.
It also has excellent thermal shock resistance, making it a great
choice for high temperature applications.

Applications:
Silicon Nitride Ceramics, originated from China, is the ideal
choice for applications that require high strength, high
temperature, wear resistance and high hardness. With its elastic
modulus at 290 GPa, compressive strength at 3800 MPa, dielectric
strength at 18-20 KV/mm, and fracture toughness at 7 MPa, SI3N4
ceramic ball is widely used in fields like engineering, aerospace,
automotive, electronic, chemical, medical, and mining. Especially
for its high temperature resistance, SI3N4 ceramic ball can be used
in high-temperature environments up to 1300℃. Moreover, its high
hardness and wear resistance make it suitable for use in situations
where components are subject to high levels of friction or
abrasion. To ensure its quality and performance, silicon nitride
ceramics can be tested with accurate and reliable methods such as
X-ray diffraction, infrared spectrometry, and thermogravimetry.
