The invention relates to a gelified thermobaric explosive mixture with non-Newtonian rheological properties which is an energetic material to be used for loading munition combat components, having an explosive-fougasse or a piercing-explosive effect, with the role of main explosive charge. According to the invention, the gelified thermobaric explosive mixture consists of a liquid organic nitrate, namely 20...40% isopropyl nitrate, an inorganic propellent powder, namely 30...50% atomized aluminum with the particle size ranging between 3...20 μm, a secondary high explosive, namely 20...40% non-phlegmatized RDX with the particle size ranging between 3...20 μm and hydrophilic colloidal silicon dioxide, in a ratio of 0.3...1.8%, the percentage being expressed by mass. Invenţia se referă la un amestec exploziv termobaric gelifiat cu proprietăţi reologice nenewtoniene care este un material energetic utilizat pentru încărcarea componentelor de luptă a muniţiilor, având efect exploziv - fugas sau perforant - exploziv, cu rol de încărcătură principală de exploziv. Amestecul exploziv termobaric gelifiat conform invenţiei este constituit dintr-un nitrat organic lichid, respectiv 20...40% procente masice de izopropil nitrat, o pulbere carburantă anorganică, respectiv 30...50% procente masice de aluminiu atomizat cu dimensiunea particulelor cuprinsă între 3...20 μm, un exploziv secundar brizant, respectiv 20...40% procente masice de RDX neflegmatizat cu dimensiunea particulelor cuprinsă între 3...20 μm şi dioxid de siliciu coloidal, hidrofil, în proporţie de 0,3...1,8% procente masice.
