Abstract

The invention discloses the application of molybdenum trioxide on dynamite preparation, which is as follows: high-power mixed dynamite is prepared from 25 to 35 mass percent of aluminum powder, 50 to 55 mass percent of molybdenum trioxide powder, 10 to 15 mass percent of simple-ingredient dynamite and 2 to 5 mass percent of insensitive agent. The invention also discloses a preparation method of the high-power mixed dynamite. The maximum density, the highest explosion heat and the highest explosion speed of the high-power mixed dynamite prepared by the invention are respectively 1.5g/cm<3>, 4.7 MJ/kg, and 9400 m/s. After explosion, the pollution of the dynamite on the environment is greatly reduced, the dynamite preparation safety is greatly improved, and the prepared dynamite has excellent stability.

Description

technical field [0001] The invention relates to the application of molybdenum trioxide in the preparation of explosives, and the application relates to an explosive, especially a high-power mixed explosive, and also relates to a preparation method of the high-power mixed explosive. Background technique [0002] Molybdenum trioxide, chemical formula MoO 3 , molecular weight 143.94. White transparent orthorhombic crystal, density 4.692g / cm 3 , melting point 795°C, boiling point 1155°C, easy to sublimate, very weak in oxidation, relatively stable at room temperature, can be reduced by hydrogen, carbon, aluminum at high temperature, made by burning molybdenum or molybdenum disulfide or roasting molybdenum acid in air have to. Molybdenum trioxide is usually used in casting molybdenum alloys, and can also be used as cathode materials for lithium batteries, electrochemical chromogenic materials and electrocatalytic materials. It is generally used as an analytical reagent in the...
