Powdered composition containing barium compound

Abstract

The objective of the present invention is to provide a powdered composition that contains a barium compound, is able to prevent the solidification of the barium compound in the high-temperature, high-humidity environment of the monsoon season to the summer season in Japan by means of an industrially advantageous method, and when barium nitrate is used as the barium compound, is able to render the barium nitrate harmless. The powdered composition containing a barium compound is characterized by resulting from including porous silica and non-porous silica in a barium compound, and the barium compound is preferably barium nitrate.

Description

technical field [0001] The present invention relates to a barium compound-containing powder composition capable of making barium nitrate non-hazardous and having excellent storage stability. Background technique [0002] Barium compounds are used as raw materials for glass, gunpowder, chimneys, and ceramics. When the barium compound is stored, agglomeration is gradually formed due to changes over time, and due to this, handling may become difficult. [0003] On the other hand, among barium compounds, barium nitrate may oxidize combustibles, causing intense combustion or explosion hazards. Extensive legal constraints. [0004] Therefore, manufacturers of barium compounds such as barium nitrate try to reduce administrative costs such as costs required for transportation and storage by preventing caking and reducing the risk of explosion or combustion. [0005] In Patent Document 1 below, it is proposed to add a BET specific surface area of ​​100 to 400 m to the barium compo...

AI Technical Summary

Problems solved by technology

[0007] According to the method of the following patent document 1, since it uses cheap silica, it is the most advantageous method industrially, but in the rainy season or in the high-temperature and high-humidity environment of summer, the agglomeration of the barium compound is likely to occur, and, It is also difficult to make barium nitrate non-hazardous

[0008] In addition, according to the methods of the following Patent Documents 2 to 4, they are industrially disadvantageous because they are expensive methods as methods for preventing caking and making them non-hazardous.
