Physicotechnical properties are provided for concretes based on mechanically-activated phosphate suspensions previously modified
with magnesium and aluminum hydroxides and silicic acid. The results obtained demonstrate the efficiency of using modifying
additions in order to increase the strength and heat resistance of corundum concretes.

Coatings and materials based on aluminum phosphate suspensions are studied that have high strength in a raw state and are
suitable for carrying out combined firing of a refractory and coating. An aluminum phosphate binder provides preparation of
high physicomechanical properties in the firing temperature range. Use of traditional mixes with a protective aluminum phosphate
coatings, and also ceramic concrete based on this binder provide increased material corrosion resistance, and consequently
an increase in object operating life and period between repairs for metallurgical and glass melting units. 相似文献

Highly concentrated ceramic binder suspensions (HCBS) based on silicon nitride are prepared and studied. The main features
of physicomechanical properties of specimens based on HCBS with heat treatment are established. The possibility is demonstrated
of using HCBS as a binder in the production of refractory material for various purposes. 相似文献

The process of manufacturing protective coatings by means of deposition of aqueous suspensions is distinguished by the simplicity
of the technological process and the low temperature at which it is realized. Phosphate-containing binders and concretes based
on these types of binders increase the resistance of the particular material to corrosive media. Through their use it is possible
to increase the service life of refractories. 相似文献

The radiochemical purity of a 131I preparation (the iodide fraction) was determined by ascending paper chromatography using a mixture of sodium iodide, sodium iodate, and sodium carbonate as a carrier and aqueous methanol as an eluent. The chromatogram was developed with a scanning β-ray spectrometer. The radiochemical purity of 131I determined by this procedure was 99.98%. The radionuclide purity of the 131I preparation was measured on a γ-ray spectrometer with an ultrapure Ge detector. The content of radionuclide impurities estimated from their detection limits in the 131I preparation isolated from TeO2 in 3–4 days after its irradiation in a reactor was no more than 0.03%. The 75Se content in the preparation aged for 6–7 months (which corresponds to a decrease in the 131I activity by a factor of 106–107 owing to decay) corresponds to 2 × 10?6% of the activity by the end of irradiation. 相似文献
