TITANIUM AMMONIUM FLUORIDE - Preparation Method
Open Data Verified Data
The raw material for industrially producing titanium is mainly rutile ore or high titanium slag (containing 92% or more of Ti02). Titanium sponge production process is based on high titanium slag and petroleum coke as raw material for the production of titanium tetrachloride. Titanium sponge can be obtained by reducing refined titanium tetrachloride with magnesium or sodium in a rare gas stream.
Magnesium reduction distillation method: the proportion of high titanium slag and petroleum coke is 100 (30~33), and the mixture is broken to less than 160 mesh, and sent to the fluidized bed chlorination furnace, and the chlorine gas is passed through the bottom of the furnace, uniformly enter the reaction section of the furnace body, and react with the mixed material of high titanium slag and petroleum coke. The reaction temperature was about 850 °c. The generated titanium tetrachloride gas is discharged from the top of the furnace and enters two separator dust collectors connected in series, so that high boiling points such as iron trichloride, iron dichloride, manganese dichloride and aluminum trichloride mixed in the titanium tetrachloride gas are deposited at the bottom of the separator dust collector. The gas was reintroduced into the two sets of condensers connected in series, and the titanium tetrachloride gas was cooled to below 136 ° C. To obtain a crude titanium tetrachloride solution. The low-boiling matters, such as silicon tetrachloride, therein are distilled off by means of a float valve column distillation. After heating to 140 ° C. In a copper chip Tower, the gasified titanium tetrachloride is passed into a copper chip Tower, and the contained impurity vanadyl trichloride is reduced by copper to a low-valent chloride of vanadium. The purified titanium tetrachloride gas discharged from the top of the column was subjected to a reduction reaction with magnesium in a rare gas stream at about 900 ° C. To obtain titanium sponge. Since the resulting sponge-like titanium also contains magnesium chloride as a by-product and unreacted magnesium, the sponge-like titanium must be placed under a vacuum of 0.1 to 10-3 Pa, the impurities were separated from the titanium by heating to about 1000 °c.

| carburizing surface treatment of titanium wire | The titanium wire forms a stable carbide with high hardness with carbon. The growth of the carbonized layer between titanium and carbon is determined by the diffusion rate of titanium in the carbonized layer. The solubility of carbon in titanium is small, the total is 0.3% at 850X:, while it is reduced to 0.1% B at 600C due to the small solubility of carbon in titanium, therefore, the purpose of surface hardening is basically only achieved by the deposition of the titanium carbide layer and the lower part thereof. Carburization must be carried out under the condition of oxygen removal, because the hardness of the surface layer formed by the powder suitable for the common carburizing of steel against the surface of carbon monoxide or oxygen-containing carbon monoxide reaches 2700MPA and 8500MPA. It is easy to peel off. In contrast, a thin titanium carbide layer may be formed during carburization in charcoal under deoxidizing or decarburization conditions. The hardness of this layer was 32 U ompa, consistent with the hardness of titanium carbide. The depth of the carburized layer is approximately greater than the depth of the nitrided layer when nitrided under the same conditions. Under conditions of oxygen enrichment it must be taken into account that the absorption of oxygen affects the depth of hardening. Only under the condition of very thin layer thickness, in vacuum or in argon-methane atmosphere, it is possible to form sufficient adhesion strength, the use of a gas carburizing agent makes it possible to form a hardened layer of titanium carbide which is particularly hard and has good adhesion. The hardening spread formed at the same time at a temperature between 950T: and 10201: is between 50 μm and 50 μm. With the increase of the layer thickness, the titanium carbide layer becomes relatively brittle, and tends to peel off t in order to avoid carbon inclusions invading the titanium carbide layer due to the decomposition of, gas carburization shall be carried out in an inert gas with the specified dosage of additive in an approximate volume fraction of 2% of rethane. Lower surface hardness results when carburizing with methane using a propane additive. When the bonding force reaches 90 kPa using gas-carburized propane, the thickness of the hardened layer is measured to be thin, but has the best wear resistance. Hydrogen is absorbed under the condition of using a gas-type cementite, but it has to be removed again during vacuum annealing. |
| content distribution | in the strata 10 kilometers thick on the Earth's surface, the content of titanium is up to 6‰, 61 times higher than that of copper, in the tenth place in the Earth's crust (Earth's elements: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium, hydrogen, titanium), arbitrarily from the ground to grab a piece of soil, which contains a few thousand of titanium, the world's reserves of more than 10 million tons of titanium is not rare. there are hundreds of millions of tons of sand and stone on the Earth. Two kinds of minerals, titanium and zirconium, which are heavier than sand and stone, are mixed in sand and stone, and are elutriated by sea water around the clock for millions of years, the relatively heavy ilmenite and zircon ore were washed together, and a layer of titanium ore and zirconium ore was formed on the long coast. This ore layer is a black sand, usually several centimeters to several tens of centimeters thick. titanium is not ferromagnetic, and nuclear submarine built with titanium need not worry about Aggression of magnetic mine. |

But its relative abundance in all elements in the tenth. [3] titanium ores are mainly ilmenite and rutile, widely distributed in the crust and the lithosphere. Titanium is also present in almost all organisms, rocks, water and soil [4]. The extraction of titanium from the main ore requires the use of the Kroll method [5] or the Hunter method. Titanium dioxide, the most common compound of titanium, can be used to make white pigments [6]. Other compounds include titanium tetrachloride (TiCl4), which is used as a catalyst and in the manufacture of smoke or aerial text, and titanium trichloride (TiCl3), which is used to catalyze the production of polypropylene. titanium alloy has high strength, and a large number of structural materials used in the manufacture of military supersonic aircraft, compression Components of jet engines, components of aircraft frames, housings, fire barriers, rivets; Structural components of air transport equipment; armored plates and propeller blades of military facilities and military ships.
