Tungsten Hydr oxides

Electro-osmosis Electro-osmosis Zeta-Meter ZM-77 

Particles were isolated from a commercial 14 mass% dispersion stabilized with acetate, containing 10 nm particles. They were then calcined at 550°C in air or in an 8% I Ij-OZC N, mixture. 

Properties 99.99% pure, average diameter 2 pm, specific surface area 2.7 rnVg [1803]. 

Solid-to-liquid ratio (0.1% by volume) was below standard level used in electroacoustic measurements (Chapter 2). Only value, data points not reported. 

2 Other Properties Particle size 836 and 360 nm (two instruments), specific surface area 13 rn7g [2153].
