Abstract
The effect of preliminary heat treatment (PHT) of hydrated cellulose fibers impregnated with an ammonium tetraborate solution on the composition and s tructure of nitrided products was studied. The PHT conditions which upon su bsequent nitriding led to the formation of C-BN fibers with a coating of BN , and also hollow and solid BN fibers, were determined.
