High Temperature Resistant 95% 99% Alumina ceramic Rod for Heating Element 2mm 3mm 4mm

 

 

1. 95% 99% alumina ceramic rod  doesn't give out toxic gases at high temperature . It is eco-friendly .

 

2. it is electrical insulating ceramic rod  .

 

3.  99%  Alumina ceramic  rod is not flexible , it is with high hardness , so it is strong and rigid in a way . However ceramic is crisp , it may break if drop to some rigid floor from a certain distance , but it depends on the shape and the way you drop it . The rod you inquired is not easy to break .

 

4. machined finish we mean after the rod was sintered , we grinding or machining it to get the surface finish and the dimension you need .

 

5. We are able to make grove at both ends of the rod of these 3 types of diameters .  Please advice what is the dimension of the grove on which diameter rod . Nomally the diameter more smaller it is more difficult to make .

Alumina Ceramic rod 

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 following photos:

 

3. Properties of the material alumina ceramic rod 

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.

Alumina ceramic rod  features : 

 

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 essential.

3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.

4. High electrical resistivity : Alumina is an electrically insulating material.

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.

 

 

Quality assurance:

1. High heat resistance : Alumina 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 : Alumina  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.
