Introduction
Refractory Corundum Ceramic Ball (also called
corundum grinding ball) is a type of high-performance ceramic
material made from high-purity alumina (Al2O3) as the main raw
material. It has excellent mechanical, thermal, and chemical
properties, making it a popular choice for a wide range of
industrial applications.
ÂÂ
Corundum ceramic balls are highly refractory,
with a melting point of around ***0°C, and exhibit excellent
thermal stability and resistance to thermal shock. They are also
highly wear-resistant, with hardness values similar to that of
natural sapphire or ruby. This makes them ideal for use in
high-temperature and abrasive environments, such as in furnaces,
kilns, and other industrial processes.
ÂÂ
The
main raw material of refractory corundum ceramic balls is
high-purity alumina (Al2O3), which is typically sourced from
bauxite or alumina hydrate. Refractory corundum ceramic balls are
available in a range of sizes and shapes, including spheres,
cylinders, and pellets, and can be customized to meet specific
application requirements. They are commonly used as packing media
in various high-temperature processes, such as gas and liquid
filtration, catalytic reactors, and heat storage systems. Corundum
ceramic balls can also be used as grinding media in ball mills and
as catalyst support in chemical reactions.
ÂÂ
Overall, refractory corundum ceramic balls
offer excellent mechanical and thermal properties, making them a
versatile and reliable material for a wide range of industrial
applications.
ÂÂ
Refractory Corundum Ceramic balls are a series
of alumina spheres that are referred to as corundum balls due to
their high alumina content. Corundum balls can be subdivided into
series of *0, *2, *5, *9, etc. according to the content of
alumina.
ÂÂ
In
addition to high-purity alumina, other materials may be added to
the raw material mixture to enhance certain properties of the
corundum ceramic ball. For example, small amounts of zirconia
(ZrO2) or magnesium oxide (MgO) may be added to improve the
toughness, corrosion resistance, or thermal conductivity of the
ceramic. However, the exact composition and additives used in the
raw material mixture can vary depending on the specific application
requirements of the corundum ceramic ball.
ÂÂ
Properties
Corundum ceramic balls have several properties
that make them highly desirable for use in various industrial
applications. Some of the key properties of corundum ceramic balls
include:
