A large number of studies have shown that there are two main methods for the hygroscopicity of ammonium nitrate (AN). One is spheroidization and the other is coating modification. In this study, numerical simulation is first performed and then spherical AN is prepared and modified by coating. In theoretical simulation section, the binding energy of …

In this video the authors present asymmetric organocatalyses performed in a ball mill. Three reaction types are being discussed: enantioselective aldol reactions, asymmetric Michael additions to nitro alkenes and dipeptide formations. In the laboratory the ball milling device is shown, and reaction details are revealed. Finally, future applications of mechanochemical …

I tried ball milling a amount of barium nitrate today,I used a PVC jar and hardened lead balls. Normally I use this jar for milling potassium chlorate, with no problems it comes out as white as snow. As the formula I'm using also contains KClO3 I wasn't worried about contamination. I milled it for one hour, after opening the jar I found that ...

The reactions were done under ball-milling condition (frequency 21 Hz), in solid state and at room temperature. The progress of the reactions was monitored by either TLC (thin layer chromatography) or 1 H NMR. 22 Thus the reaction time and yields were optimized.

to have a target go boom. Would ammonium nitrate and diesel fuel work the same, detonate with a rifle shot? Just wondering because I keep some diesel around for the tractor/mower, sure would be easier than ball milling aluminum. So, just out of curiosity, would the ammonium nitrate combined with

The scratches of plastic hardware, especially ball milling jars, will store traces of chemicals. This applies also to the ball milling media. You must have enough application-specific hardware to make sure, that even traces of incompatible chemicals may not interact. ... Ammonium nitrate is hygroscopic, and will draw moisture from the air. With ...

A mixture of aluminum powder and ammonium nitrate can be used as an explosive. A number of explosions in which ammonium nitrate and aluminum are mixed with carbon, hydrocarbons, with or without oxidizing agents, have occurred. ... A mixture of powdered aluminum and carbon tetrachloride in a ball mill exploded. Impact sensitivity tests have ...

The nanocrystalline ceria is produced by solid state high energy ball milling (HEBM) and liquid state solution combus tion synthesis (SCS) method. The liquid state route consists of a high temperature combustion reaction to form ceria from an aqueous solution of cerium ammonium nitrate (CAN) as an oxidizer and citric acid (CA) plus glycine (G ...

Ammonium nitrate, without a reasonable amount of fuel had essentially zero risk of detonating. Obviously, this does not apply to grinding premixed pyrotechnic materials that include ammonium nitrate and fuels. Thus still will not result in a detonation, but could very well ignite and burst the grinder or blender.

It took 12 boxes of these 1/2" diameter lead balls (from Bass Pro) to fill the mill jar half full, which is the ideal media "charge" in this1-gallon jar …

SUMMARY OF THE INVENTION. In an ammonium nitrate-aluminum powder-water slurry explosive, an improved explosive is obtained when the aluminum powder consists of aluminum powder (a) which is manufactured by the ball milling method or the stamping method, the particle size of which is 30 mesh (JIS sieve) or below, and aluminum powder (b) having no ...

Evaluating the Pros And Cons of Ammonium Nitrate . Ammonium (NH 4 +) and nitrate (NO 3 –) are the two forms in which plants can directly utilize nitrogen from the soilUpon application of ammonium nitrate fertilizer, it easily dissociates into these two forms When ureabased fertilizers are used, conversion of urea to ammonium occurs for a period of one …

Nanometer (nano) ammonium perchlorate (AP) and ammonium nitrate (AN) were prepared with 2D network structures by the ultra-low temperature spray method. Scanning electron microscopy (SEM), X-ray diffractometry (XRD), differential scanning calorimetry (DSC) and thermogravimetric analysis/infrared spectrometry (TG-IR) were employed to probe the micron structure, crystal …

Ammonium nitrate is used to make fertilizers, while petroleum products are accessible everywhere. In the explosions, forensic and bomb squad teams have identified ball bearings, nails as some of the shrapnel mixed with ammonium nitrate …

This may be readily achieved in any of several convenient ways, including by way or non-limiting illustration: aqueous solution blending of the chromium compound and the ammonium nitrate followed by crushing and wet ball milling; melt blending followed by crushing and ball milling; direct mixing of the pulverized chromium compound and ammonium ...

Pour the silver nitrate and ammonium nitrate solution into the glass ball, followed immediately by the sodium hydroxide solution. Cover the opening of the glass ball with a piece of parafilm and swirl the solution, making certain the entire interior surface of the glass ball is covered. You will see a silver mirror coating from inside the ball.

Here, ammonium nitrate (NH 4 NO 3) is specifically adopted, acting as the solid nitrogen source during ball milling. The starting material with a fixed 2:1 wt ratio of amorphous Fe 78 Si 9 B 13 powder to commercial ammonium nitrate (Alfa Aesar, 99.999% purity) was used.

For this particular experiment, weigh 0.1 mmol (8.0 mg) of ammonium nitrate (NH 4 NO 3) in the half of the jar with other solid reactants. 7. ... The metal milling balls can be cleaned in the same ...

The charachteristics of the burning wood carry on through the charcoal heres an example of burning speed. hardwood ok.pine faster.and balsa extremely fast not saying that hardwood wont make good bp but it needs to be milled longer.make sure you have good quality kno3 and not ammonium nitrate.whan milling you want your jar at least half full of ...

Page 3 of 16 - Ball Milling FAQ - posted in Newbie Questions: The starter post says that using a blender is a bad idea when making BP. I've previously read that rocket candy and other nitrate/sugar combination's can bemilled in the blender if the ingredients are milled individually then combined. While I'm not an expert on the subject it should be possible to use …

We report here a methodology of chemo- and regio-selective aryl bromination and iodination using respective N-halosuccinimides at room temperature in the absence of any solvents, catalyst/additives under ball-milling condition. However, for chlorination ceric ammonium nitrate was used as additive. The coupled product succinimide, produced from ...
