Production name : Natural rutile sand Natural rutile sand is a relatively pure natural TiO2 mineral, typically containing over 95% TiO2. It is an important mineral raw material for titanium extraction, but its reserves in the earth's crust are relatively small. It exhibits excellent properties such as high temperature resistance, low temperature resistance, corrosion resistance, high strength, and low specific gravity. Currently, global reserves of natural rutile are gradually depleting, and production is declining year by year. It belongs to the tetragonal crystal system and often forms well-preserved tetragonal columnar or needle-like crystals, with aggregates presenting as granular or dense blocky structures. It is dark red, brownish red, yellow, or orange-yellow, and appears black in the presence of high iron content; its streak is yellow to light brown. It has a diamond-like luster, while ilmenite exhibits a semi-metallic luster. It is brittle, with a hardness of 6 to 6.5 and a density of 4.2 to 4.3 g/cm3. Main applications include: manufacturing high-grade welding electrodes, welding flux, and auxiliary materials such as flux-cored welding wires; producing titanium dioxide and titanium tetrachloride; smelting titanium metal and titanium alloys; and manufacturing photocatalytic products.
Calcined natural rutile (C-RTL-A)

Production name: Calcined natural rutileCalcined natural rutile is a product obtained by high-temperature calcination of natural rutile containing over 90% TiO2 in an industrial furnace. Under high-temperature conditions, the crystal water and free water in rutile ore are eroded, resulting in extremely low moisture content. At the same time, the low-melting oxides and organic additives in the ore are also eroded at high temperatures. The calcined natural rutile is purer, with high TiO2 content, low moisture content, low sulfur, and low phosphorus characteristics. Main applications: manufacturing auxiliary materials for high-grade welding electrodes, welding flux, and flux-cored welding wires.
