| Typical chemical / physical properties | excellent chemical resistant at high temperature (1600°C), high thermal resistant | abrasion resistant, chemical resistant, thermal shock resistant | excellent resistant to crack growing high thermal shock resistant |
| chemical corrosion resistance* | The materials are resistant to corrosion of acid and alkali in gaseous and liquid form, except hydrofluoric acid |
||
| * Chemical corrosion cannot be excluded at high temperatures / high concentration. | |||
