| Abstract | A thermohydrolysis process is considered for aluminum chloride hexahydrate as one of repartition stages for a hydrochloric acid technology of alumina production from Russian high-silicon raw materials. A physicochemical study is performed for the burning of AlCl$_{3}$ · 6H$_{2}$O, and the temperature ranges for the removal of water and chloride ions are determined. It is shown that chloride ion is released mainly as HCl. The effect of burning temperature on the phase composition and the basic physical properties of the alumina powder (specific surface area, porosity, and average particle size) is studied. The results of optical and electron microscopy showed that the alumina particles retain the hexagonal structure of the source of aluminum chloride hexahydrate. It is established that ultrasonic treatment affects the dispersion level of the aluminum oxide powder. The data obtained allow one to produce metallurgical alumina of “sandy” type which can be used to prepare aluminum metal by means of electrolysis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
