SYNTHESIS OF THE SILVER ACETYLIDE - YouTube
The heat liberated is not sufficient to gasify the products andthe explosive effect is entirely due to the rapidity of liberation of heat andits expansive effect on the adjacent air (this is akin to what occurs in anatomic bomb, where all the energy output is radiative and the blast results fromthe expansion of the surrounding air as it absorbs the energy and heats up).
Silver Acetylide is very sensitive to shock, friction and heat, exploding violentlywhen ground hard between two solid surfaces or when struck by a solid blowbetween two hard surfaces.
Plasmodynamic Synthesis of Nanodispersed Silicon Carbide
Silver Nitratewas chosen as the silver donor for the first synthesis as it is bothreadily soluble in water (1 gram per 0,4ml at 25C) and is easily available atreasonable prices, much like Acetylene gas.
Tewodros (Teddy) Asefa is currently a professor in the Department of Chemistry and Chemical Biology and the Department of Chemical and Biochemical Engineering at Rutgers University in New Brunswick, NJ. He is also a member of the Rutgers Institute for Materials, Devices, and Nanotechnology (IAMDN) and the Rutgers Energy Institute (REI). In December 2009, he helped to put together the Rutgers Catalysis Research Center (RCRC). His group at Rutgers is involved in the development of synthetic methods of a wide array of functional and core/shell nanomaterials and the investigation of their potential applications in catalysis, electrocatalysis, targeted delivery of drugs to specific cells, nanocytotoxicity, solar cells, and environmental remediation. He is a recipient of the National Science Foundation (NSF) CAREER Award (2007–2012), the NSF Special Creativity Award in 2011, the Rutgers Board of Governors Research Fellowship in 2012, and multiple federal and local research grants. He was named the National Science Foundation American Competitiveness Fellow (NSF ACIF) in 2010 and also serves as a panelist for several federal and international agencies. He has recently coedited a book on nanocatalysis (Wiley) and has written over 120 peer-reviewed scientific papers and several book chapters over the past decade.

The multinuclear silver carbide cluster aggregate in 3 is encapsulated by two Py6 ligands through both metal–ligand coordination and cation−π interactions, spotlighting a new synthetic strategy for supramolecular capsules.
The alternate name "silver carbide" is rarely used, ..

It is not lightsensitive, unlike the acetylide formed by the method outlined above.
The precipitation of SA in neutral and nitric acid solution goes faster andcleaner than in ammonicial solution.
Explosive Properties for the ammonia-precipitated silver acetylide are asfollows:
Deflagration with release of soot (C) , dull explosion(report).

The brazing process can employ various heat sources such as torch, flame, acetylene, gas/air, induction, resistance, infrared, oven, and furnace. The process of brazing uses filler metals and alloys such as silver, copper, and zinc. Flux is necessary for brazing to remove and prevent reformulation of surface oxides on the base metals.

At some point in time ChemLabs was a fully equipped laboratory with over 150 analytical grade reactants and various pieces of specialized lab glassware and equipment available, suitable for performing almost any conceivable non-industrial chemical procedure or synthesis.
The laboratory described here was my second chemical lab (the first one was located in Holland and didn't have a fraction of what this one had) and was assembled over a period of approximately one year, during which a couple thousand dollars was invested in every obtainable reagent as well as all the equipment required to handle those reagents, and a couple hundred hours went into using these reagents to synthesize reagents which could not be obtained: This was the case for all the Perchlorates, Nitrates (except NaNO3), Chlorates (except NaClO3), paraformaldehyde, Hexamine, Styphnic and Picric Acid, and others, although the more hazardous chemicals were only synthesized when needed, so as to reduce any danger associated with storing unstable chemicals.
This page continues to be updated as time permits: several other experiments still need a write-up.
Please note the following:
PowerLabs does NOT sell any type of chemicals, or distribute any information about these topics aside from what is made available here.
