Method for providing crystalline silicon-containing ceramic material

A method for enhancing crystallinity and limiting thermal damage in formation of a reinforced silicon-containing ceramic material, the method comprising:

• providing a porous structure and a silicon-containing preceramic polymer material, the silicon-containing preceramic polymer material being thermally convertible into a silicon-containing ceramic material, wherein
• a percent crystallinity of the silicon-containing ceramic material is a function F1 of a temperature and time at which the silicon-containing preceramic polymer material is thermally converted, and
• a degree of thermal damage to the porous structure is a function F2 of the temperature and the time at which the silicon-containing preceramic polymer material is thermally converted,
• providing the silicon-containing preceramic polymer material with dopant particles dispersed therein to shift upwards the function F1 of the percent crystallinity;
• infiltrating pores of the porous structure with the silicon-containing preceramic polymer material having the dopant particles dispersed therein;
• and
• thermally converting the silicon-containing preceramic polymer material, at the temperature and given time, to a crystalline silicon-containing ceramic material.
