Joint i.r. and microcalorimetric work has shown that two types of CO adsorb on pure anatase: one (species A) absorbing at 2184–2188 cm–1, has an adsorption heat of ca. 52 kJ mol–1, the other (species B), absorbing at 2203–2208 cm–1, has an adsorption heat of 69 kJ mol–1. When sulphates are present at the surface, left…

The relative sensitivity of an analytical electron microscope and energy-dispersive x-ray detector to x-rays of various elements is investigated through an extensive kASi factor study. Elemental standards, primarily National Bureau of Standards multielement research glasses, were dry-ground into submicrometer-sized pa…

Barium ferrite fine particles have been synthesized from ferric nitrate and barium nitrate aqueous solution by an aerosol technique. The as-received particles showed a spin-glass behavior with a history-dependent low-field magnetization below 180 K. An exothermic peak with an initial crystallization temperature of 687…

Treatment of VOCl42– with tca–(tca–= thiophene-2-carboxylate) under aerobic conditions leads to formation of [V5O9Cl(tca)4]2–, whereas if AgNO3 is also present, the product is [V4O8(NO3)(tca)4]2–; the two anions have been isolated as NR4+ salts and their unusual structures elucidated by crystallographic methods.

Seeding a mixture of boehmite (AIOOH) and colloidal ZrO 2 with α‐alumina particles and sintering at 1400°C for 100 min results in 98% density. The low sintering temperature, relative to conventional powder processing, is a result of the small alumina particle size (∼0.3 μm) obtained during the θ‐to α‐alumina transform…

Physicochemical and catalytic properties of heteropolyacids of the series H3 +nPVnMo12–nO40(n= 0–3), both pure and supported on the potassium salt K3PMo12O40, have been investigated. Thin acid coats formed on such a support display modified properties and enhanced thermal stability. In particular, it is postulated tha…
