Abstract
A polycarbodiimide compound is reacted with an organic compound having at least two amino groups in the molecule. A polycarbodiimide compound is reacted with an amine compound having a silicon atom in the molecule. The carbodiimide bonds remained in the crosslinked material are further crosslinked. The crosslinked material is further heated/calcined to obtain an inorganic material having high heat resistance and strong toughness.
