Description of Telluride Copper CoTe Powder ：

Telluride copper, also known as alloys C145, Copper tellurium (also called alloys 145),145 semi-shared tellurium, and TEU- is a copper-based alloy containing different amounts of tellurium. Tellurium usually has a content of 0.4-0.7%, and phosphorus can be anywhere from 0.004-1.12 percent.

Copper tellurium can be described as an alloy made of copper tellurium. Copper tellurium containing 0.4-0.7% tellurium has good machinability. The master alloy is telluride copper, which contains half the amount of copper and half the percent of tellurium.

Tellurium Copper has the following properties:

• Atmospheric corrosion resistance.
• High temperature and conductivity hydrogen embedment (i.e., caused by the introduction or diffusion of hydrogen fracturing, weaken) 65-130 HV hardness.
• Good formability (if free cutting Brass for 100), 85-90% of machinability rating, suitable for welding and brazing.

However, it is inappropriate for spot welding, oxygen-acetylene welding, resist welding, and coating metal arc welding.

It is a copper alloy with excellent machinability and high electrical and thermal conductivity. Copper tellurium alloy is known for having the best cutting performance. It is forged, cast, extruded, drawn, blanked, and molded. The tellurium copper alloy can be made into plates, sheets, rods, wire, tubes, and many other forms. It is ideal for industrial use due to its properties. If you are interested in Telluride Copper CuTe Powder, please inquire.

Telluride copper cuTe powder performance:

Copper telluride can be described as a chemical substance having the molecular structure CuTe. Copper telluride can be described as a dark powder. It is very stable in ambient air and at room temperature. Copper telluride, an inorganic mineral essential for storing copper and tellurium resources, can also be held significantly. Cu is used to replace Te in H2SO4 solutions. Copper telluride can be produced by replacing Te. It separates tellurium from many metal ions, creating a very high concentration. Te can either be + 4 or 6 valences when it returns Te. These can all generate Cu 2 Te. This is because He isn't affected by the tellurium valence. Cu telluride, when exposed to an acid or base, can react chemically with these acids and bases. This is the key to separating and recovering Cu and T. Simply put, copper and tellurium combine at higher temperatures to dissolve the tellurium.

How does Telluride Copper CopperCuTe Powder be made?

Direct synthesis

Direct synthesis is a standard production method of copper telluride, which directly reacts copper and telluride at high temperatures to obtain copper telluride. The specific steps are as follows:

The higher-purity copper and tellurium elements are prepared; copper is usually present in bulk or granular form, and tellurium is generally present in powder form.

Place the copper blocks or particles and tellurium powder into the quartz tube, ensuring the ends are closed.

The quartz tube is placed in a heating furnace and heated to the appropriate temperature (usually 600-800 ° C).

The high temperature is maintained for some time (e.g., several hours) to allow the copper and tellurium to react fully.

At the end of the reaction, the quartz tube is removed, cooled, and opened to reveal the resulting copper telluride crystals.

The advantages of direct synthesis are simple operation and easy availability of raw materials. However, it should be noted that the purity of copper telluride obtained by this method may not be high enough, and further purification is needed. In addition, the direct synthesis method has a higher cost and is unsuitable for mass production.

Electrolysis

Electrolysis is a method of preparing compounds by electrolysis of a solution, which can be used to produce high-purity copper telluride. The specific steps are as follows:

Dissolve an appropriate amount of copper salts (such as copper nitrate) and tellurium salts (such as tellurium chloride) in a solvent (such as water) to obtain a mixed solution.

The mixture is poured into the cell, and a voltage is applied to both electrodes.

During electrolysis, copper and tellurium ions are reduced to copper and tellurium on the anode and deposited on the cathode to form copper telluride.

The copper telluride deposited on the cathode is collected for cleaning and drying.

The advantage of electrolysis is that high-purity copper telluride can be prepared, and the cost is relatively low, which is suitable for large-scale production. In addition, copper telluride can be controlled by electrolysis by adjusting the solution concentration and electrolytic conditions. However, it should be noted that the electrolysis method requires electrolytic equipment, and the operation is more complicated.
