10.9 Tables of Properties

The materials covered in the following tables find widely different applications. For this reason some of the data are not given. As a general rule, electrical and mechanical applications can be differentiated. Those materials classified according to DIN EN 60 672-1 are given minimum specifictions for application in electrical and electronic engineering, but are also applied elsewhere. Flexural strength for technical ceramic materials are determined according to DIN EN 60 672-2 (see p. 263 ff.).

10.9.1. Materials according to DIN EN 60 672-3
10.9.1.1. Alkali aluminium silicates (C 100) Table 36
10.9.1.2. Magnesium silicates (C 200) Table 37
10.9.1.3. Titanates (C 300) Table 38
10.9.1.4. Alkaline earth – aluminium silicates (C 400) Table 39
10.10.1.5. Aluminium and magnesium silicates (C 500) Table 40
10.10.1.6. Mullite (C 600) and aluminium oxide (C 700) Table 41
10.10.1.7. Other oxide ceramic materials (C 800) and Table 42
                Non-oxide materials (C 900) for insulation purposes

10.9.2. Non-standardised high-performance materials
10.9.2.1. Oxide ceramics (Al2O3, PSZ, SiO2) Table 43
10.9.2.2. Carbides (SiC, BC) Table 44
10.9.2.3. Nitrides (SN, ALN) Table 45
10.9.2.4. Other materials (ATI, MgO) Table 46

Due to the wide range of property values quoted by manufacturers, the values given in the following tables are indicative or minimum specification values. The actual values are often much better! It is therefore advisable to request reliable values from the manufacturers.


Note:
The values for bending strength, , determined by the 3-point bending test, are about 30 % greater than those obtained from the 4-point bending test!
