Ceramic hybrid ball bearings using ceramic balls
Ceramic bearing balls can weigh up to 40% less than steel ones, depending on size and material. This reduces centrifugal loading and skidding, so hybrid ceramic bearings can operate 20% to 40% faster than conventional bearings. This means that the outer race groove exerts less force inward against the ball as the bearing spins. This reduction in force reduces the friction and rolling resistance. The lighter balls allows the bearing to spin faster, and uses less energy to maintain its speed.

While ceramic hybrid bearings use ceramic balls in place of steel ones, they are constructed with steel inner and outer rings; hence the hybrid designation.

Ceramic Sliding Disc Valve
Ceramic Sliding Disc Valve for abrasive and corrosive mediums
Main specifications:
Nomunal pressure:1.06.3MPa
Nomunal diameter :DN40DN300
Suitable media: Desulfuration,Dusting,Coal injection,Silicon powder converying
Suitable temperature :-20500
1Ceramic to ceramic sealing
The Sliding disc valve trim consists of three ceramic parts,one sliding disc and two stationary ceramic seats.The sliding disc is moving vertically and sealing against the seat directly.Compared with the traditional gate valve, it has long service life for there is no dead-space free,impact or impulse.
2Abrasion resistant The hardness of the ceramic disc and seats is upto HRA88, maybe it is only less than Diamond.So the ceramic sliding disc valve has an outstanding performance in many high abrasion and wear applications.
3Corrosion resistant
Fine ceramic owns excellent chemical inertness , Almost no reaction with all chemical medium so the ceramic sliding disc valve can be excellent used to high-corrosion mediums. The design of sealing structure keep the medium from contacting the valve body cavity.
4High strength The ceramic disc is protected by a metal holder,and the stem drives the disc through the holder,and the ceramic disc will not damaged for sudden shock.
5Zero leakage
With many years experience in ceramics machining,zero leakage is ensured for its high accuracy,the surface roughness and flatness of the sealing face are less than 2um.And the ceramic disc and seats grinding against themselves when open/close,for that the tightness of the valve is enhanced.
6Without block
The mediums especially which contains solid particle will not block the valve for the through conduit design and the unique dead-space free structure, that is why the ceramic sliding disc valve is very suitable for the abrasive and/or corrosive conditions.

Zirconia Ceramics Components
Zirconia Ceramics Components
Introduction
Zirconium oxide occurs as monoclinic, tetragonal and cubic crystal forms. Densely sintered parts can be manufactured as cubic and/or tetragonal crystal forms. In order to stabilise these crystal structures, stabilisers such as magnesium oxide (MgO), calcium oxide (CaO) or yttrium oxide (Y2O3) need to be added to the ZrO2.
Other stabilisers sometimes used are cerium oxide (CeO2), scandium oxide (Sc2O3) or ytterbium oxide (Yb2O3).
Properties
FUBOON is good at yttria stabilized zirconia. Unlike other ceramic materials, zirconia is a material with very high resistance to crack propagation. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.
high fracture toughness
thermal expansion similar to cast iron
extremely high bending strength and tensile strength
high resistance to wear and to corrosion
low thermal conductivity

Zirconia Ceramics Components
Zirconia is most famous high-performance material among all oxide ceramics. Ceramic components made out of Zirconia generally consist of Zirconia as basic material doped with some percentage of other oxides like Yttria (Y2O3) or Magnesia (MgO). Depending on doping material different material properties could be achieved because of influencing the Yttria's microstructure. The "ceramic steel" titled Zirconia is doped with Yttria forming an ultra-fine ductile structure with sub-micron grain formation leading to enormous bending strengths. Magnesia doped qualities are less strong also showing a coarser microstructure.
Zirconia is characterized through its tribological performance (friction and wear) in moving applications and furthermore:
Excellent fracture toughness
Very good wear resistance
High corrosion stability
Low thermal conductivity
CTE in range of steel ■
