Generally, SiOC aerogels are prepared utilizing the high-temperature pyrolysis of polyorganosiloxanes or polycarboorganosilanes in an inert gas atmosphere. However, the crosslinking and drying of the precursor rely on the catalysts of noble metal, th

Nanofibrous aerogels constructed by ceramic fiber components (CNFAs) feature lightweight, compressibility, and high-temperature resistance, which are superior to brittle ceramic aerogels assembled from nanoparticles. Up to now, in order to obtain CNF

High-strength silica aerogels were prepared successfully by a new two-step surface modification (TSSM) method via ambient pressure drying (APD). Methyltrimethoxysilane (MTMS) and Trimethylchlorosilane (TMCS) were used as silylating agents in TSSM. Fi

The SiO2-deposited Al2O3-SiO2 aerogel (Si-ASA) with high thermal stability and mechanical properties was synthesized by silica deposition method during aging. Compared with the ASA without silica deposition, the Si-ASA maintains higher specific surfa

During the preparation of coatings on porous Si3N4 ceramics, stress cracks often occur due to the sintering mismatch between the coating and substrate. To solve this problem, in this work, a Si3N4/BaO–Al2O3–SiO2 (BAS) coating with a heterogeneous

Traditional solid nanoparticle aerogels have been unable to meet the requirements of practical application due to their inherent brittleness and poor infrared shielding performance. Herein, combining vacuum impregnation and high-temperature pyrolysis

A simple, rapid and efficient approach for the monoclinic celsian glass-ceramic fabrication is proposed here. The first step was preparing the amorphous BaO–Al 2 O 3 –SiO 2 glass powder (BAS, with a eutectic temperature of 1400 °C). The second s
