This part we introduce complexes synthesized by hydrothermal method containing inorganic polyacid, bipyrindine, organic polyacid, pyridine-carboyxlate, and mixed polyacid and polybase ligands.
The types of deposits basically are differential metasomatism in the later magma, pneumatolytic hydrothermal process, pegmatite process, residual deposits and placer deposits.
Generation of uranium was closely related to migration and escaping of natural gas and may be also relevant to hydrothermal solution activities during epigenesis period.
In this paper the relationship between the crystal forms and the growth mechanism of quartz and tinstone under the hydrothermal solution conditions has been studied.
The alabandite and getchellite of hydrothermal origin, cement anatase of alkaline volcanic origin, and the high content of chlorite in coal were fist found in coals.
The hydrothermal synthesis method was adopted to prepare the rutile-type nano-sized TiO2 by using low-cost metatitanic acid as the starting reactant and the monacid as the dressing agent.
