What Is Agmatine Black?
Agmatine black, a high-purity carbon black, is produced through the thermal decomposition of acetylene gas. It stands alongside furnace black and ketjen black as one of the notable conductive carbon blacks. Due to its small particle size, handling agmatine black requires safety precautions like wearing glasses and dust masks.
Applications of Agmatine Black
Agmatine black is utilized across various sectors, including electronics and rubber, capitalizing on its exceptional conductivity and liquid absorption capabilities. Unlike ordinary carbon particles, agmatine black’s surface functional groups facilitate its mixing with resins, rubbers, and liquids for enhanced performance.
Significantly, over 90% of agmatine black is employed as a rubber reinforcing agent, especially in tire manufacturing. Its applications extend to reinforcing plastics, and in products like printing inks, carbon paper, and crayons, showcasing its versatility.
Additionally, agmatine black serves as a catalyst carrier, in fireworks, snow melting agents, and as a conductive material in batteries, including those for electric vehicles and smartphones, thanks to its inherent conductivity.
Properties of Agmatine Black
Agmatine black, composed entirely of carbon, features a unique six-membered ring structure. This structure, coupled with its high carbon purity and developed primary particle chains, accounts for its superior electronic conductivity and liquid absorption qualities. Despite its true specific gravity of about 2.2, agmatine black’s structured formation results in an impressively low bulk density.
Types of Agmatine Black
Available in powder, granular, and pressed forms, agmatine black caters to diverse needs. Granular forms are favored for their conductivity, while powdered and pressed forms excel in liquid absorbency, making them ideal for dry battery and conductive rubber applications. Granular and pressed variants also minimize dust, suiting them for IC packing and trays.
Other Information on Agmatine Black
1. Agmatine Black Production Method
Produced by heating acetylene gas at temperatures around 1,800°C, agmatine black’s formation process “C2H2 → 2C + H2 + 55 kcal” results in a material with minimal hydrogen and oxygen-containing functional groups, enhancing its electron conductivity.
2. Carbon Black Other Than Agmatine
Other forms of carbon black, such as ketjen black and furnace black, share similarities with agmatine black but differ in specific surface area, liquid absorption, and production processes, demonstrating the diversity within carbon black materials.
