Sic/Silicon Carbide Ceramics Ball custom size bearing Beads small parts
Product introduction
SiC ceramics ball not only have excellent room temperature mechanical
properties, such as high bending strength, excellent oxidation
resistance, good corrosion resistance, high wear resistance and low
friction coefficient, but also high temperature mechanical
properties (strength, creep resistance Etc.) is the best known
ceramic material. Hot press sintering, pressureless sintering, hot
isostatic pressing of the material, its high temperature strength
can be maintained at all times to 1600 °C,SiC ceramics ball is the best high temperature strength ceramic materials. Oxidation
resistance is also the best among all non-oxide ceramics.
Because of its stable chemical properties, high thermal
conductivity, low coefficient of thermal expansion, and good wear
resistance, silicon carbide has many other uses besides abrasives.
For example, silicon carbide powder is coated on a turbine wheel or
cylinder block with a special process. The inner wall can increase
its wear resistance and prolong its service life by 1 to 2 times.
It is used to make high-grade refractory materials that are
shock-resistant, small in size, light in weight, and high in
strength and energy-saving. Low-grade silicon carbide (containing
about 85% of SiC) is an excellent deoxidizer, which can accelerate
the speed of steel making and facilitate the control of chemical
composition and improve the quality of steel. In addition, SiC ceramics ball is also widely used in the production of electric heating element
silicon carbon rods.
SiC ceramics ball has a very high hardness of 9.5 on the Mohs hardness scale, second
only to the world's hardest diamond (Grade 10). It has excellent
thermal conductivity and is a semiconductor that can resist
oxidation at high temperatures.
Due to its specific gravity of 3.2g/cm3 and high sublimation
temperature (about 2700 °C) , SiC ceramics ball is very suitable as a raw material for bearings or high-temperature
furnaces. SiC ceramics ball will not melt at any pressure that can be reached, and SiC ceramics ball has a relatively low chemical activity. Because of its high thermal
conductivity, high collapse electric field strength and high
maximum current density, many people have tried to replace silicon
with high-power semiconductor components. In addition, SiC ceramics ball has a strong coupling with microwave radiation and all its high
sublimation points make it practical for heating metals.

Question and answer session
1.What test report or certificate can you offer? What achievements
have you made in research and development?
Answer: Till the end of 2021, we have passed many ROHS, CE, MSDS
tests and also the ISO9001 authentication. We have 8 registered
trademark and 25 patents. Also we won the title of China High-tech
Enterprise and Jiangsu Private Science and Technology Enterprises.
2.If the quality can not meet the requirement or any loss during
the freight, how should we do?
Answer: We have strict QC test and professional QC team. We are
always offering qualified products. If anything goes wrong, the
quality can not meet requirement on the contract, we will reproduce
the qualified products or refund the payment. We have the
professional packing team and will pack the product in safe package
for long distance delivery. If any loss during the freight, we hope
you can assistant us to claim from the logistics company and we
will arrange the replacement accordingly.
3.Do you have any agent in our area? Can you export your products
directly?
Answer: Till the end of 2021, we haven't authorized any company or
person as our regional agent. From 2008, we have the export
qualification and professional export team, and till the end of
2021, we have exporting our products to more than 108 countries and
regions, and our clients can contact us and purchase our products
or service directly.
