Abstract: The influence of degassing method , calculation model , and adsorption pressure on the specific surface area tested result of nano-grid triaminotrinitrobenzene (n-TATB) was researched by a surface area and pore size analyzer . The results show that the proper degassing method can accelerate the volatilization speed of foreign substance and water absorbed by the surface of n-TATB . Brunauer - Emmetr -Teller calculation model is suit for the specific surface area analysis of n-TATB and the optimal test relative pressure is in t he range of 0.05 to 0.25. n-TATB is a kind of slit-macropores material including some micropores and mesopores.
Keywords: nano-grid triaminotrinitrobenzene; specific surface area; pore distribution
