Step 6, is 200-260 degree Celsius of lower presintering 1-3 hour by idiosome at normal pressure and temperature, is then to slowly warm up to
600-900 degree Celsius of roasting 2-5 hour, then be warming up to 1200-1550 degree Celsius and sinter 3-6 hour, it is placed on cool place after sintering
Place is cooled to room temperature and i.e. can get final products.
