ANFO makes up about 80% of all explosives used in the United States each year. Ammonium nitrate has various uses in various industries. Ammonium nitrate is a crystal-like white solid which is made in large industrial quantities. Interactive image; ChemSpider: 24223 ECHA InfoCard: 100.033.257: EC Number: 236-598-7; PubChem CID. Uses of ammonium nitrate. Ammonium nitrate is predominantly used in agriculture as a fertiliser. Ammonium nitrate is used in the high explosive ANFO (ammonium nitrate/fuel oil). Uses of ammonium nitrate. Ammonium nitrite Identifiers CAS Number. This makes it harder to light. Ammonium nitrate burns colder then potassium nitrate. It is used as an absorbent for nitrogen oxides, an ingredient of freezing mixtures, an oxidizer in rocket propellants, and a nutrient for yeast and antibiotics. Ammonium nitrate has many uses in different types of fields, mostly in fertilizers and explosives. Ammonium nitrate is used commonly in fertilizers; in pyrotechniques, herbicides, and insecticides; and in the manufacture of nitrous oxide. In most countries, it is used to make explosives for mining, quarrying and civil construction because of its low cost and ready availability. The chemical is applied in granule form into the soil and quickly dissolves under moisture, allowing nitrogen to be released. Ammonium nitrite, NH 4 NO 2, is the ammonium salt of nitrous acid. It is popular because it is a cheap and highly stable explosive. 13446-48-5 3D model . Another use of ammonium nitrate is in the food industry where it is used as a nutrient in producing antibiotics and yeast. A typical fuel adds something like sulphur to make it easier to light, and aluminum to make it burn hotter. We will focus on the two most common uses – explosives and fertilizers. Fertilizer. It is not used in pure isolated form since it is highly unstable and decomposes into water and nitrogen, even at room temperature. But it produces more gas per gram. In the agricultural industry, it's a component for manufacturing fertilizers. Uses. This is one of the most popular explosives for a variety of applications such as; coal mining, quarrying, and in construction. Generally, ammonium nitrate is used as a fertilizer.
