Alumina Ceramic Bushings / Sleeves
At the present time the special position in area of equipment for
dwelling houses and production facilities is occupied by electric
heating devices which key elements are, surely, tubular electric
heaters (TEHs). Ceramic bushings, being mounted at the ends of a
tubular heater, provide its electrical insulation and
air-tightness. Thus, we manufacture the products which can be found
almost anywhere – in electric boilers, autoclaves, washing
mashines, water heaters, electric hot plates, etc. Such a broad
scope of usage results in a wide diversity of ceramic bushings’
forms and sizes, and just some of them are shown here at the
3. Properties of the material alumina
alumina ( Al2O3) is an extremely refractory material. It possesses
excellent chemical inertness and corrosion resistance at
temperatures well above the melting point of alumina. Innovacera
Zirconia is fully stabilized in the cubic crystal structure to
avoid cracking and mechanical weakening during thermal cycling. In
addition to its high temperature capability, Zirconia offers low
thermal conductivity and is electrically conductive above 800ºC.
Also has the unique ability to allow oxygen ions to move freely
through the crystal structure above 600ºC.

Characteristic: Resistance to strong acid, strong alkali, salt and
gas of deleterious, long life, high hardness, resistance to wear,
especially resistance to hydrofluoric acid.
Ceramic parts are more resistant to heat meaning more reliable,
better performing, longer lasting, and they are electric insulation
can be used in many fields.
Zirconia sleeves are widely used in electrical industry, ceramic
industry, oil industry, food industry, medical industry, chemical
industry etc. to replace metal sleeves.
If you are interested in this product or just want to know more

Zirconia ceramic(also can be called zro2,zirconium oxide ceramic)
has high toughness,high fracture resistant,good chemical
resistance,high bending strength,high wear resistance,the
coefficient of thermal expansion is close to steel,it is widely
used in structure ceramicareas.
Zirconia (zro2 ) has a wide application due to its versatility and
low material cost. zirconia possesses a high melting point, strong
hardness, and good chemical stability, making it a good material to
withstand high temperature and chemical corrosion. zirconia Plates
and Disks are available in different dimensions and thicknesses.

Product features :
Applicable to make ceramic wrist watch, watch ctrap, bracelet, ring
and necklace etc. With the property of abrasion resistance,
invariant color, elegance and shining, ceramics are the ideal
decorative material for watch and jewelry industry. All the
ceramics can be customized.
1. High hardness.
2. High heat resistance : Alumina ceramic has excellent thermal
stability,which means that it is
widely used in areas where resistance to high temperatures is
3. Good wear resistance : Alumina ceramic is the material of choice
for alumina wear parts.
4. High electrical resistivity : Alumina is an electrically
5. High corrosion resistance : It is insoluble in water and only
slightly soluble in strong acid and
alkaline solutions. Good chemical stability of alumina leads to
high corrosion resistance.
1. High heat resistance : Zirconia ceramic has excellent thermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
2. Good wear resistance : Zirconia ceramic is the material of
choice for wear parts.
3. High corrosion resistance : It is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
Alumina ceramic is the most mature of the engineering ceramics,
offering excellent electrical insulation properties together with
high hardness and good wear resistance,but relatively low strength
and fracture toughness.Alumina ceramics are generally white but may
also be pink or ivory.The color is derived from either the
sintering additives or impurities in the raw materials.
