Not necessarily. As described above, the ceramic which is obtained from the pyrolysis of a cured sample of Ceraset Polysilazane 20 or Ceraset Polyureasilazane at 1,000° C is an amorphous, non-glassy ceramic. The chemical composition of this ceramic depends on the pyrolysis atmosphere (see Technical Bulletin TB2 included at this website). Crystallization typically occurs at temperatures between 1,400° C and 1,600° C and depends on the exact chemical composition of the ceramic which is obtained at 1,000° C.
