The high-temperature stability of the SiC ultrafine fibers is limited by the massive amounts of
oxygen introduced during the oxidative curing process. In this study, vinyl-modified …

Large-scale production of SiBN ceramic fibres was achieved by the pyrolysis of N-
methylpolyborosilazane. This precursor was prepared by a three-step synthesis starting from …

Oxygen free Si-C fibers {open_quotes} Hi-Nicalon {close_quotes} with C/Si ratio of 1.39 and
{open_quotes} Hi-Nicalon S {close_quotes} with C/Si ratio of 1.05 were synthesized from …

SiBCN ceramics have excellent high-temperature stability and anti-oxidation properties, and
they are candidates for materials used at extreme conditions. In this paper, amorphous …

A novel polyborosilazane (PBSZ) precursor was synthesized via single source precursor
route, in which B existed in the form of B–N hexatomic ring in the main chain. The …

Most polycrystalline SiC-based fibers were prepared at a sintering temperature higher than
1600° C. In this work, a ZrO 2 reinforced SiC-ZrB 2 polycrystalline fiber was prepared at …

Core-shell ceramics fibers with multiple composition are ideal candidates for thermal
insulation application at high temperature. Herein, ultrathin C–SiC/ZrSi x O y C z core-shell …

A rapid method for synthesizing β‐silicon carbide (β‐SiC) fine fiber composite has been
achieved by combining forcespinning technology with microwave energy processing. β‐SiC …

Infusible but soluble polycarbosilane (PCS) was obtained by heating Yajima PCS at 300° C
for 1 h with 1–wt.% of polyborazine (PBN). The simple addition of PBN to PCS and …

Abstract Polymer-derived ceramics (PDCs), such as silicon oxycarbide and its derivatives,
show an exceptional high oxidative stability under extreme conditions. A novel …
