What is the density of pyrolyzed Ceraset Polysilazane 20 or Ceraset Polyureasilazane?
Even though the ceramic yield of cured Ceraset Polysilazane 20 or Ceraset Polyureasilazane is quite high (85-96 wt% depending on the pyrolysis atmosphere) some mass loss occurs. This mass loss is manifest as homogeneous porosity throughout the pyrolyzed polymer rather than shrinkage. Typically, bulk densities are around 2 – 2.5 g/cm3. When pyrolysis is performed below crystallization temperatures (below about 1,400° C to about 1,600° C) an amorphous, non-glassy ceramic is formed.
