1. A method for preparing a boron nitride nanotube (BNNT)-silicate glass composite, the method comprising:
mixing BNNTs that are coated with boron oxide with a silicate glass precursor to create a mixture, the BNNTs that are coated with boron oxide prepared by:
obtaining BNNTs that are coat with mollen boron oxide; and
cooling the BNNTs that are coated with the mollen boron oxide to obtain the BNNTs that are coated it boron oxide;
heating the mixture to obtain a molten silicate glass; and
cooling the molten silicate glass to obtain the BNNT-silicate glass composite.
