文摘
- •
Zirconium and aluminum oxyhydroxides 25–44 nm particles were obtained during sol–gel synthesis.
- •
Growth rate of primary particles in mixed Zr–Al solution is twice higher than in pure.
- •
Reduction of carbamide concentration from M:carbamide = 1:3 to 1:1.75 leads to increasing of particles growth rate by 1.7 times.
- •
Nanoparticles form highly porous structures due to aggregation of 50–60 nm particles in 1–10 渭m clusters.
