Abstract

The invention discloses a preparation method of metagermanate. Auxiliary materials for preparing the metagermanate comprise potassium or sodium. The content of germanium dioxide (GeO2) is greater thanor equal to 99.995%; the pressurizing pressure ranges from 30.0 kg / cm<2> to 70.0 kg / cm<2>; the preparation temperature is between 200 DEG C and 280 DEG C; raw materials of germanium dioxide, auxiliary materials and water are prepared, and the auxiliary materials comprise one of potassium hydroxide or sodium hydroxide; the ratio of germanium dioxide to the auxiliary materials is metered and blended according to a chemical reaction equation; a feeding hole of an autoclave is opened, the prepared raw materials, auxiliary materials and water are fed, and the feeding hole is closed; a magnetic steel cooling water switch is switched on, a stirrer is switched on, and after 5 minutes, the rotating speed is adjusted to 150-300 revolutions per minute; an electric heating switch is switched on; whenthe pressure rises to 30 kg / cm<2> or above and 70 kg / cm<2> or below, and the temperature rises to 200 DEG C or above and 280 DEG C or below, the temperature is kept for 5-6 hours, heating is stopped,and naturally cooling is carried out.

Description

technical field [0001] The invention relates to a method for preparing metagermanate, and the product is especially suitable for application on crops that need to absorb germanium, such as cultivating ganoderma lucidum and the like. Background technique [0002] Ge-132 (β-carboxyethyl germanium half oxide)—(GeCH 2 CH 2 -COOH) 2 o 3 , clinically used to prevent and treat cancer, it is believed that germanium tetravalent elements can replace oxygen, and when used as human nutrition, it can increase pure oxygen in the body, known as "oxygen generator". Germanium brought into the human body from plants (as high as 0.075% and 0.03% germanium in garlic and Korean ginseng, respectively) helps prevent cancer, and spiral germanium and its derivatives also have this medicinal effect. [0003] Germanium and selenium have a synergistic effect, and organic germanium plus an appropriate amount of organic selenium can significantly improve the curative effect of treating coronary heart...
