mohsite - Physico-chemical Properties
| Physical and Chemical Properties | Ilmenite is one of the main titanium-bearing minerals. Three party crystal system, Crystal rare, often irregular granular, scale-like, plate-like or plate-like. Color iron black or steel gray, gray or black bars steel, when containing hematite inclusions, brown or brown red. Metallic to semi-metallic luster, shell-like or sub-shell-like fracture. Friable nature. The hardness is 5~6, the density is 4.4~5g/cm3, and the density increases with the decrease of MgO content or the increase of FeO content in the composition. Weakly magnetic. In hydrofluoric acid solubility is larger, slowly soluble in hot hydrochloric acid. After dissolving in phosphoric acid and cooling dilution, add sodium peroxide or hydrogen peroxide, the solution is yellow-brown or orange-yellow. Ilmenite can be produced in all kinds of rock mass, widely distributed in the basic rock and acid rock; In the pegmatite, the particle size is larger, up to several centimeters. When the ore-bearing parent rock is destroyed by weathering, ilmenite can be transferred to sand ore. |
mohsite - Introduction
Ilmenite is an important iron-titanium oxide ore with the chemical formula fetio3. The following is a description of the nature, use, preparation and safety information of ilmenite:
Nature:
1. Ilmenite is black crystal or granular solid with metallic luster.
2. The density is about 4.5-5.0g/cm³.
3. The melting point of Ilmenite is about 1545 ° C, and it has a certain thermal stability.
Use:
1. Ilmenite is an important titanium resource, mainly used in the production of titanium alloy and titanium dioxide.
2. Titanium alloy has the characteristics of high strength and corrosion resistance, and is widely used in aerospace, automotive, medical equipment and other fields.
3. Titanium dioxide is an important white pigment, widely used in paint, plastic, paper and other industries.
Preparation Method:
1. The most commonly used preparation method is to obtain metallic titanium by calcining titanium iron ore.
2. The method of preparing titanium alloy is usually smelting and alloying ilmenite with other metal elements (such as aluminum, vanadium, zinc, etc.).
Safety Information:
1. Ilmenite is non-toxic and non-irritating to the human body under normal conditions.
2. However, under high temperature and high pressure, ilmenite may produce toxic titanium dioxide smoke and dust, so it is necessary to take appropriate protective measures when handling and processing ilmenite.
3. The mineral dust and powder of ilmenite may cause irritation to the respiratory system. Dust masks and gloves should be worn during operation to ensure good ventilation.
