CONSTRUCTION RULESOF TECHNICAL CERAMICS

BSQ TECH GmbH offers you professional advice and support in the design of your parts according to the design rules of technical ceramics. 

​

When designing components from technical ceramics, there are certain rules that should be considered to ensure that the material achieves its desired functionality and reliability. Here are some design rules for technical ceramics:

1. Avoid Sharp Edges and Corners: Since ceramic is brittle, sharp edges and corners can easily break or cause cracks. It is therefore advisable to use radii or roundings on the edges.

2. Avoid Sudden Changes in Thickness: Sudden changes in thickness can create stresses that can lead to cracks and fractures. It is recommended to create gradual transitions between different thicknesses.

3. Use generous radii on holes: Since ceramic is brittle, holes can also cause the material to break. It is recommended to use generous radii on the holes to minimize stress.

4. Avoid Slots and Nicks: Slots and nicks can create stresses that can lead to cracks and breaks. It is recommended to minimize or avoid the use of slots and notches.

5. Use a generous fit: Due to the low toughness of ceramics, a too tight fit can easily lead to cracking. It is recommended to use generous fits to minimize stress.

6. Consider the thermal properties: ceramics have low thermal conductivity and high heat storage capacity. It is important to take this into account when designing components, especially in applications with high temperature differences.

7. Consider the Electrical Properties: Ceramic is a good insulator and is used in many applications as an electrical insulation material. It is important to consider electrical properties when designing components.

By following these design rules, technical ceramic components can be manufactured that are highly reliable and durable.

Ceramics: strengths

1. Technical ceramics offer a multitude of advantages and strengths compared to other materials such as metals, plastics or other ceramics. Here are some of the main strengths of technical ceramics:

2. Hardness and Wear Resistance: Engineering ceramics have high hardness and wear resistance, making them ideal for applications where the material is subjected to high stress.

3. Corrosion Resistance: Technical ceramics are resistant to many chemicals and acids and can be used in corrosive environments.

4. Temperature Resistance: Technical ceramics can withstand extreme temperatures, from very high to very low temperatures. Some ceramics can even be used at temperatures in excess of 1000°C.

5. Electrical Insulation: Engineering ceramics are excellent electrical insulators and can be used in applications where electrical insulation is required.

6. Biocompatibility: Some technical ceramics are biocompatible and can be used in medical applications such as implants.

7. Chemical purity: Technical ceramics can be made very pure, making them ideal for applications in the chemical and food industries.

8. Lightweight construction: Some technical ceramics have high strength and low weight at the same time, which makes them interesting for applications in lightweight construction.

9. Low Friction: Some engineering ceramics have low friction, making them ideal for applications where high wear resistance and low friction are required.

10. Overall, technical ceramics offer a unique combination of properties that make them attractive for a wide range of applications in different sectors and industries.

Ceramics: Weaknesses

1. While technical ceramics offer a variety of strengths and advantages, there are also some weaknesses and challenges that need to be considered when using this material. Here are some of the main weaknesses of technical ceramics:

2. Brittleness: Engineering ceramics are brittle and tend to crack or crack when subjected to severe stress. This means that when constructing ceramic components, particular attention must be paid to stress and strain.

3. High Cost: The production of technical ceramics requires special processes and materials, which can lead to higher production costs than other materials such as metals or plastics.

4. Difficult Machining: Technical ceramics can be difficult to machine as they are very hard and brittle. This can lead to higher processing costs and longer processing times.

5. Sensitivity to Impact Loads: Technical ceramics are sensitive to impact loads, which can lead to cracks and fractures. Therefore, components made of technical ceramics should be handled with care.

6. Limited Design Options: Technical ceramics may have limited design options due to the difficult machining and brittle nature of the material.

7. Poor Thermal Conductivity: Compared to other materials such as metals or carbon fibers, technical ceramics have poor thermal conductivity, which can limit its use in some applications.

8. Overall, the use of technical ceramics requires careful consideration of the advantages and disadvantages with regard to the specific requirements and applications. Although technical ceramics have some limitations, they can still be beneficial in many industries and applications, especially where their specific properties are in demand.

Where is the art of construction?

The art of constructing technical ceramics lies in understanding the specific properties of this material and taking them into account in the construction. In contrast to other materials, technical ceramics have special properties that must be taken into account when designing parts and components.

An important consideration when designing technical ceramics is the brittle nature of the material. Because technical ceramics can easily break or crack, it is important to design to minimize stress on the ceramic component. This can be achieved by using rounded edges, reinforcements or other design elements.

Another important aspect when designing technical ceramics is the consideration of the thermal and electrical properties of the material. Technical ceramics can typically withstand high temperatures and are excellent insulators, making them an ideal material for applications in high-temperature electronics or the automotive industry. However, when designing ceramic components, care must be taken to take into account the thermal and electrical properties of the material to ensure optimal performance.

Finally, the construction of technical ceramics also requires an understanding of the machining and manufacturing processes required for this material. The difficult processing of technical ceramics often requires specialized tools and machines as well as trained professionals to ensure that the material is processed correctly.

Overall, the art of constructing technical ceramics requires an in-depth understanding of the specific properties of this material, as well as careful planning and design to ensure the parts and components can perform as required.
