Products Description

Chromium targets have the same properties as chromium metal (Cr). Chromium target is a steel-gray, shiny, hard and brittle transition metal. In a vacuum, the chromium target can produce a relatively stable chromium ion beam, which makes it useful for making substrates or surface coatings to protect the substrate or to make some industrial parts that require high oxidation resistance. Chromium targets can also be used to study the stoichiometric ratios of chromium compounds.

The production of chromium targets is a precise and complex process.

First, the original chromium element needs to be purified through a series of processes such as high-temperature smelting, refining and electrolysis. The purified chromium element is then processed into the desired target shape and size by mechanical or thermal processing methods. In this process, the control accuracy and purity of the material are extremely high, and any negligence can affect the performance of the final product.

Chromium target properties

The excellent properties of chromium targets are mainly attributed to the characteristics of chromium elements.

Chromium has a high melting point and good oxidation resistance, so that the chromium target can remain stable in high temperature environment. In addition, the electron beam deposition and magnetron sputtering characteristics of chromium targets make it a unique advantage in high-tech fields such as microelectronics process and optical coating.

Application field

Chromium targets have a wide range of applications in the automotive industry. In order to form a bright coating on wheels and bumpers, chromium targets are excellent materials. Such as automotive glass coating, chromium sputtering targets can also be used;
Chromium has high corrosion resistance, which makes chromium targets suitable for obtaining corrosion resistant coatings.

In industry, hard material coatings obtained through chromium targets optimally protect engine components, such as piston rings, from premature wear, thereby extending the service life of vital engine components;
Chromium targets can also be used in photovoltaic cell manufacturing and battery manufacturing.

In short, chromium sputtering targets are used in many fields, including physical deposition films and functional coatings (PVD method) for electronic components, displays and tools; Vacuum chrome plating for watches, household appliance parts, hydraulic cylinders, slide valves, piston rods, colored glass, mirrors, automotive parts and accessories, and other machines and equipment.

Chromium metal for other applications
Chromium metal is mainly used as raw materials for the production of various alloys, and is widely used in chemical industry, automobile, shipbuilding, aviation, nuclear reactor, military industry and other industries. Industrial production of metal chromium mainly adopts thermite chromium and electrolytic chromium method in two ways, the product is flake or block, and the chromium target is made of pure chromium powder chromium products, often as the surface coating modification process evaporation source, widely used in locks and hardware tools, lamps, auto and motorcycle decorative strips and car mirrors, bathroom faucets, mechanical tools and IT products shell and buttons

Chromium target preparation technology

Mix the metal chromium powder with a particle size of 60-320 mesh and the metal chromium powder with a particle size of 320-500 mesh evenly, dry and set aside. The mass ratio of the metal chromium powder with a particle size of 60-320 mesh to the metal chromium powder with a particle size of 320-500 mesh is 5:3 and 9:2.

The mixed chromium powder is added into the cold pressing die, and cold pressed at a pressure of 700 MPa to 100 MPa to form a solid cylinder of the required size as the chromium target blank, with a holding time of 1 second to 120 seconds. The surface of the chromium target blank is wrapped with covering paper and then placed into the hot pressing die and put into the furnace.
Evacuate to 0-15 Pa, heat up to 300°C - 400°C, hold for 10 - 30 minutes, then continue heating to 600°C - 800°C, stop heating, activate the hot pressing equipment, align the upper and lower pressing heads of the hot pressing equipment, and pre-press the chromium target material blank at a pressure of 8 - 12 MPa for 60 - 90 seconds; turn off the hot pressing equipment, continue heating to 1300°C - 1600°C, hold for 30 - 120 minutes; then activate the hot pressing equipment again, hot press and form at a pressure of 20 - 10 MPa, hold the pressure for 1 - 10 minutes, cool down to 100°C and take out of the furnace to obtain the chromium target material.
