“…Thongkasam's group describes the appearance of cristobalite from a diatomite mainly composed of quartz (CD from Lampang Province, Thailand) when it is treated at 1100°C [50]. Lazutkina et al [51] present the transition among b-quartz and a-quartz in Irbitskii diatomite (Sverdlovsk Region, Russia) in the range of 610 and 800°C and between 652 and 740°C for Kamyshlovskii diatomite (Sverdlovsk Region, Russia). Another report done by Mohamedbakr and Burkitbaev, presents a change in crystalline phases as well as the formation of agglomerates or clusters through sintering when CD from Aktyubinsk (Kazakhstan) is thermally treated at 900°C [52].…”

Diatomite samples from Costa Rica were purified using acidic treatments with hydrochloric acid, thermally treated (400-1000°C) and then silylated with trimethylchlorosilane in toluene under inert atmosphere. The purification process allows to decrease the concentration of metals presented in the crude diatomite, as is confirmed by X-ray Fluorescence (XRF) Analysis. The silylated materials were analyzed by using Hyperpolarized 129 Xe Nuclear Magnetic Resonance Spectroscopy (HP 129 Xe NMR), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), rehydration tests, and contact angle measurements. XRD measurements indicate that diatomite is mainly amorphous, but presents several crystalline phases (kaolinite, cristobalite, and quartz). Pretreatments at high temperatures cause changes in those crystalline phases, resulting in more amorphous materials. However, there is no difference in the overall structure of purified and thermally treated diatomite samples with respect to the silylation products. In addition, SEM measurements show no effect over the pore structure of the materials. On the other hand, TGA measurements and rehydration tests show lower losses of water for silylated materials prepared using higher pretreatment temperatures. Moreover, HP 129 Xe NMR, FTIR, and contact angle measurements evidence a modification due to covalent attachment of Si(CH 3 ) 3 -groups to the surface, which increases for higher pretreatment temperatures. The results provide valuable information about external factors that influence the surface modification of diatomite. This can be useful to control modifications that can be achieved in a similar way.

“…It is important to note that any large-scale production requires a local raw material base. The possibility of using amorphous raw materials in both silicate enamel technology [8][9] and foam glass technology [10][11][12][13] has been confirmed by a number of studies. Therefore, the presence of extensive deposits of amorphous silica [14] and silica-bearing rocks in Eastern Siberia and the Far East, as well as the possibility of synthesizing amorphous silica from quartz-containing raw materials [15] makes it possible and necessary to develop the proposed technology for integrated protection of pipelines in the evolving network of oil and gas pipelines of the Russian Far East.…”

Modern trends in the development of Russian oil and gas infrastructure are examined. The important role of the Far East in the transportation and export of oil is revealed. The main threats in the operation of pipelines are described. The integrated protection technology of pipeline surfaces is proposed. The structure and properties of local silicate raw material – diatomite – are studied. The technology of obtaining glass enamel coating is designed to protect the internal surface of the pipe. The phase composition, microstructure and properties of the coating are compared with analogues. The technology of foam glass production is designed to protect the external surface of the pipe. The foaming processes are studied; the properties and structure of the material are examined. The optimum ratio of raw materials is revealed. Recommendations on the application of the developed technology for integrated pipeline protection are given.

Modern trends in the development of the oil and gas infrastructure of the Russian Far East are considered. The main threats in the operation of oil and gas pipelines are described. The technology of complex protection of pipeline surfaces is proposed. Protection of the inner surface is achieved through the use of silicate enamel coatings, protection of the external surface – through the use of foam glass. On the basis of local silicate raw materials the technology of the described materials is developed, and their main properties are determined. Recommendations on the application of the developed technology for the protection of pipelines are given.
