1. The ceramic products must be reliable and
cost must be optimized.
Ceramic materials are brittle and their
strength is influenced by external stress.
Ceramic materials have low thermal
conductivity and electrical
Avoid material accumulations and stress
concentrations.

2. IMPORTANT DESIGN GUIDELINES
 Oval parts should be avoided. In the case of a circular
form a more homogeneous stress distribution will occur
during loading.
 Modular structures are preferred to lower component
volume and improve reliability. The probability of having
defects in a small volume is lower than in a large volume.

3.  The ceramic component is prestressed with a
compressive load, and hence tensile stresses are
minimized. Choosing an arch instead of a beam converts
tensile into compressive stresses in this case.
 Separate the nodes. Avoid thick ends on moldings.

4. Avoid sudden changes in cross-sectional area.
• Provide large contact areas.
Avoid corners and sharp edges, around inner edges, and
cut-outs.
Avoid long, sharp edges (risk of breakage).

6. HEATED OXYGEN SENSOR(HO2S)
ZrO2 ceramic is the main material in this device.
Used for controlling gasoline injection to minimize
emission
behavior: The oxygen sensor (A) measures the oxygen
content in the exhaust gas, which leads to
information about the gasoline-to-air ratio in the
combustion chamber. This information, more or less
an mV-signal, is forwarded to the control unit (B)
