Abstract
The present application relates to boron nitride nanotube (BNNT)-silicate glass composites and to methods of preparing such composites. The methods comprise mixing BNNTs that are coated with a glass former such as boron oxide with a silicate glass precursor to create a mixture; heating the mixture under conditions to obtain a molten silicate glass; and cooling the molten silicate glass under conditions to obtain the BNNT-silicate glass composite.

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.
