B4C–SiC composite ceramics are a very promising alternative to pure B4C ceramics and
pure SiC ceramics. B4C–SiC composite ceramics exhibit a combination of the desirable …

Recently, silicon carbide–boron carbide composite ceramics have attracted more and more
attention. The most important achievements of the silicon carbide–boron carbide composite …

Boron carbide (B 4 C) is an important structural ceramic material, however, the use of this
material is limited by its poor sinterability and low fracture toughness. Nano-sized powders …

Boron carbide-alumina (B 4 C–Al 2 O 3) composite ceramics were fabricated using boron
carbide (B 4 C) as the matrix and alumina (Al 2 O 3) as the second phase by hot-press …

A strategy for improving the specific stiffness of silicon carbide (SiC) ceramics by adding B 4
C was developed. The addition of B 4 C is effective because (1) the mass density of B 4 C is …

Abstract B 4 C/SiC (15 wt%) ceramic composite with 2 wt% carbon additive was fabricated
via solid-phase pressureless sintering under an argon atmosphere for 60 min between …

Abstract The B 4 C-LaB 6 composite ceramics were fabricated via hot-pressing sintering at
2050° C and 20 MPa pressure with the mixture of boron carbide (B 4 C) and 2–5 wt …

Boron carbide (B 4 C) matrix composites had the advantages of high hardness, high melting
point and low density. However, due to the low relative density and poor fracture toughness …

Abstract Dense B 4 C–SiC–CrB 2 ternary composites were fabricated via reactive hot
pressing with B 4 C and chromic silicides (84 wt% CrSi 2+ 16 wt% CrSi) as raw materials …

Abstract Small amount of TiB2 (< 5 wt%) was added into B4C through a novel method that
combines the use of sputter deposition and hot pressing. Sputter deposition provided more …
