Calcium carbide 2–7mm is mainly used in applications requiring rapid and controllable acetylene generation, including:
Laboratory acetylene gas production;Chemical synthesis and fine chemical processes;
Small acetylene generators;Research institutes and pilot-scale testing;Special industrial processes with precise gas control.
Compared with larger sizes, calcium carbide 2–7mm offers:
Faster reaction speed with water;Better control over acetylene generation;More uniform performance in laboratory and chemical experiments;
Reduced reaction delay in small acetylene systemsThis makes it an ideal choice for precision-demanding applications rather than bulk industrial use.
Inner Mongolla Kullant Chemical Co., Ltd. operates its own production facilities in Inner Mongolla, China.
All calcium carbide products are manufactured under strict quality control systems to ensure consistent particle size and stable gas yield.
Third-party inspections such as SGS, BV, or CIQ are available before shipment upon request.
