Si, C and SiC

*2: Attention: the sample can not be ground with water as after a time of app. 15min a reaction with a strong aerosis comes out. The whole sample was pushed out through the seals of the lid!! A corrosion of the grinding bowl has to be expected!!

*3: In order to avoid a possibly reaction through higher temperature the p-7 was programmed as follows: grinding time 5min + 15min pause + 5x repetition = 30min grinding time a.s.o. for 60min resp. 120min.
