摘要

Process for the manufacture of light plastic compositions for processing into heat-resistant or refractory materials A process for the manufacture of light plastic compositions for processing into heat resistant or refractory materials containing at least 74% by weight ceramic fibres comprises loosening 100 parts by weight ceramic fibres and mixing in 1 to 3 parts by weight dry organic bonding agent. 10 to 50 parts by weight water is sprayed onto the mixture and then 10 to 30 parts by weight clay mixed in. Finally a viscous solution of an organic bonding agent in amount corresponding to 1 to 3 parts by weight of dry organic bonding agent is mixed in.
