Technical terms such as high-performance ceramics, structural ceramics, construction ceramics, industrial ceramics,
Engineering ceramics, functional ceramics, electro ceramics, cutting ceramics and bio ceramics describe special aspects of technical ceramics.
Ceramics have to date been considered in a variety of new applications where high hardness, high wear resistance, high corrosion resistance and good high temperature stability combined with low specific gravity are required.
The new high-tech materials achieve high strength.
Their values are comparable to the values of metals and generally surpass all polymers. The properties of ceramic materials are largely determined by the respective microstructure.
The mechanical and physical characteristics can be influenced in different directions by the targeted adjustment of certain microstructures, the so-called microstructure design.
One essential aspect must always be taken into account when using ceramics: "Ceramics are brittle"! Due to their ductility, metallic construction materials are "balanced and good-natured" materials that sometimes forgive minor design errors (fault tolerance), since 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 by 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 bending and tensile strength.
Compared to metals, ceramics are particularly suitable for use at high temperatures, since the characteristic values of ceramic materials are far less affected by temperature loads and only at higher degrees than those of metals.
Ceramics behaves in a similarly positive manner with regard to corrosion and wear. Because of these advantages, we encounter technical ceramics at every turn.
Many household appliances would not function without ceramic insulating parts. A reliable power supply would also be unthinkable without insulators and safety components made of technical ceramics.
Ceramic substrates and components form the basis for components and assemblies in all areas of electronics, and in mechanical and plant engineering, sliding and control elements ensure wear and corrosion-free function.
Ceramic is indispensable as a construction and insulation material for industrial furnaces in high-temperature technology! Even these few examples clearly show that technical ceramics plays 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.
PROCESS STEPS THE 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.
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).
Micro injection molding
3D printing LCM
Consistent quality is based on qualified manufacturing processes, the regulations and results of which are routinely monitored and recorded.
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.
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.
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.
Determine the manufacturing process
Determine material (Al2O3, ZrO2, SiC, Si3N4)
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.
