Technical ceramics is the future

MANUFACTURING PROCESS OF TECHNICAL CERAMICS

We support all manufacturing processes, so that their product is manufactured according to the best practices, taking into account the price-performance ratio.

Terms used in the literature such as high-performance ceramics, structural ceramics, construction ceramics, industrial ceramics,

Engineering ceramics, functional ceramics, electro ceramics, cutting ceramics and bioceramics describe special aspects of technical ceramics.

  • Raw materials and powder

    Basic requirements of production and the most economical manufacturing process determine the selection of raw materials (type, purity, grain size and specific surface) as well as other auxiliary materials.

    1. Alumina

    2. Zirconium oxide

    3. Silicon nitride

    4. Silicon carbide

  • Mass preparation

    The ceramic manufacturer obtains the raw materials and carries out all further processing steps himself or the ceramic manufacturer purchases processable materials and begins the ceramic process with the shaping.

    1. Grind

    2. Mix

    3. Filter

    4. Granulate

    5. Plasticizing

    6. Spray drying

  • Engineering

    In solving a technical problem, the engineer or designer must design technical elements. In the case of ceramic materials, he must pay particular attention to the required material-specific design.

    1. Determine requirements

    2. construction

    3. Technical drawing

    4. application

    5. Determine quality

    6. Determine the manufacturing process

    7. Determine prices

    8. Define quantities

    9. Determine material (Al2O3, ZrO2, SiC, Si3N4)

    10. Send offer

  • Shaping

    Here, the powder particles are compressed and brought into a coherent shape that has sufficient strength for subsequent handling.

    The selection of the suitable shaping process is usually based on economic considerations (rational production).

    1. Dry pressing

    2. Extrude

    3. Foil casting

    4. Injection molding

    5. Micro injection molding

    6. Isostatic pressing

    7. 3D printing LCM

    8. Alumina

    9. Zirconium oxide

    10. Silicon nitride

    11. Silicon carbide

  • Green processing White processing

    Green processing takes place on dried components that still contain organic additives.

    The white processing takes place on pre-fired components that are free of organic additives. The strength is determined by the pre-firing.

    1. Milling

    2. Rotate

    3. Drill

    4. Saws

    5. grind

    6. Lapping

    7. polishing

    8. Honing

    9. Metallizing

    10. Glazing

    11. Assembly

    12. substitution

  • Finishing

    Hard machining

    The final processing or hard processing takes place on completely fired components, which have already been brought as close as possible to the final dimensions through the shaping, green or white processing. The tightest tolerances can be achieved by removing finishing processes.

    1. grind

    2. Lapping

    3. polishing

    4. Honing

    5. Metallizing

    6. Glazing

    7. Assembly

    8. substitution

    9. ...

  • Quality inspection

    Consistent quality is based on qualified manufacturing processes, the regulations and results of which are routinely monitored and recorded.

    1. Optically

    2. Dimensional check

    3. Crack testing

    4. Strength test

    5. Roughness testing

    6. Screwing test

    7. Surface inspection

    8. Hardness test

    9. ...

IMPROVEMENTS WITH TECHNICAL CERAMICS

TECHNICAL CERAMICS IS THE MATERIAL OF THE FUTURE

 

Why?

Ceramic has to date been considered in a large number of new applications in which high hardness, high wear resistance, high corrosion resistance and good high temperature stability, combined with a low specific weight are required.

The new high-tech materials achieve high strengths. Their values ​​are comparable to the values ​​of metals and generally exceed all polymers.
The properties of the ceramic materials are largely determined by the respective structure or microstructure. Through the targeted adjustment of certain microstructures, the so-called microstructure design, the mechanical and physical parameters can be influenced in different directions.

When using ceramics, one important point must always be taken into account: "Ceramics are brittle"!

 

Metallic construction materials are due to their ductility "balanced and good-natured" materials, which forgive even minor design errors (error tolerance), as they are able to reduce local stress peaks through elastic and plastic deformation.

In addition, the metals are generally characterized by good electrical and thermal conductivity and characteristic values ​​that are independent of the spatial direction.

 

Ceramic materials, on the other hand, are usually electrically and thermally insulating, have a high degree of hardness and can have very low thermal expansion. Due to the lack of plastic deformability, they are also extremely dimensionally stable.

 

Compressive strengths are achieved that can be ten times the flexural and tensile strength. Compared to metals, ceramics are particularly suitable for use at high temperatures, as the characteristic values ​​of ceramic materials are influenced by temperature loads far less and only at higher degrees than those of metals. Ceramic behaves in a similarly positive manner with regard to corrosion and wear.

 

Because of these advantages, we come across technical ceramics at every turn. Many household appliances would not work without ceramic insulating parts. A reliable power supply would also be inconceivable without insulators and fuse components made from technical ceramics.

 

Ceramic substrates and components form the basis for components and assemblies in all areas of electronics, and sliding and control elements in mechanical and plant engineering ensure wear-free and corrosion-free functionality.

 

In industrial furnaces in high-temperature technology, ceramics are indispensable as a construction and insulation material! Even these few examples clearly show that technical ceramics play an important role in our world.


However, ceramic components are usually not visible at first glance. Nevertheless, they play a decisive role in conventional applications and also in innovative products, such as in dental technology with dental implants and in the luxury goods segment with black watch cases made of zirconium oxide ceramic.

 

The potential of technical ceramics has not yet been exhausted.
