We’re manufacturing vacuum vessels in-house for both of Polaris’ formation sections.
These vacuum vessels are made of fused silica (quartz). We make these in-house by powering three graphite electrodes inside a spinning mold filled with silica sand. While the sand spins in the mold, the electrodes heat the inner layer of sand, melting it into place to form a quartz tube.
Shown here is an early test, running at 20% of the full power used during the tube manufacturing process.
This is very cool! I can suggest a couple of ways this video could have been more dynamic, if the camera had panned around and/or over the cylinder, or zoomed in as the process was happening, for example. I’ve got a resume in for the Creative Specialist role that I saw just was reposted today, give me a call, I’ll make these videos pop!
Our Arc Melt Furnace ABJ-900-3 with the Crystal Growth option is the larger cousin of our TA-200, featuring a larger chamber, larger power supply, top loading instead of bottom loading for easier access, and larger melts. The crystal growth components are set up to grow single crystals of semiconductor materials, metals, salts and synthetic gemstones using the Czochralski method.
This furnace has three electric stingers, for simultaneously melting material with three arcs in three different places. This furnace is capable of melting materials above 3500°C. A crystal seed attached to the seed rod then lowers into the center crucible of the 9″ (225 mm) hearth holding the melt and is
programmed to pull the growing crystal.
The pulling speed is fully programmable and controls accurately as low as 0.001 mm/min. The 3/8” seed rod has an adjustable rotational speed from 0-30 rpm. The maximum pull height is 7″ (176 mm).

Exciting Developments in Surface Treatment!
Did you know that chromising, pioneered by Diffusion Alloys in the 1950s, is a game-changer in surface treatment? Chromising, or chromizing, involves the diffusion of chromium into base metals at high temperatures, creating an alloy with exceptional properties. Originally designed to protect industrial gas turbine blades, this technique has evolved to serve diverse industries, from oil & gas to renewables.
Chromised coatings, devoid of hexavalent chromium, offer robust protection against type II corrosion, wear, and oxidation. Low, medium, and high carbon steels, stainless steels, and nickel-cobalt superalloys benefit from tailored chromising solutions.
Diffusion Alloys employs two cutting-edge processes—pack cementation, and slurry—each with unique applications. From large-scale components to precise local repairs, our facilities boast state-of-the-art air and protective atmosphere furnaces. We're not just coating surfaces; we're enhancing performance and durability.
Discover how chromising is reshaping the future of material protection and paving the way for innovation in various industries.

Harness the potential of a RoQuench Melt Spinner.
PSI's high performance planar flow spinning systems produce amorphous and microcrystalline metallic ribbons under varying atmospheric conditions.
As the molten metal comes into contact with the spinning substrate, it rapidly solidifies.
Metal melt spinners are used in various applications, from creating magnetic materials and high-strength alloys to producing metal fibers for reinforcement in composites. The process's ability to rapidly cool metals allow for the production of materials with unique properties, such as amorphous or fine-grained structures, that are often not possible through traditional metallurgical methods.

🧲Ribbon magnet production system is contain arc melting and melt spinning units.
🔘The Arc Melting (Edmund Buehler, AM200) is used to melt samples on a laboratory scale in a protective atmosphere. In addition, alloys with a high melting point can be produced. The rapid cooling rate enables the formation of metastable phases or the desired microstructure.
🔘The Melt Spinner (Edmund Buehler, MSP60) is a tool for the production of rapidly solidified amorphous or nanocrystalline ribbons or splats on a laboratory scale, either in high vacuum or inert gas atmosphere. The alloys are heated by induction in a suitable crucible with slit or round nozzle and ejected on a copper wheel with overpressure. The melt rapidly solidifies and leaves the wheel as a ribbon.
#VacuumCoating
Tungsten molybdenum alloys are widely used in vacuum coating industry, where tungsten is often used to make hot cathodes (or hot wires) for coating electron guns. Tungsten has high melting point, good thermal conductivity and mechanical strength, suitable for working at high temperature conditions, and can produce stable electron emission.
Tungsten and molybdenum alloys are commonly used to make other components of electron guns, such as crucibles, heat shields, etc. Tungsten molybdenum alloy has good high temperature resistance, corrosion resistance and mechanical strength, suitable for vacuum coating environment of various parts manufacturing.
Tungsten twisted wire is a kind of strip metal tungsten product made by twisting and stranding several tungsten wires with a certain diameter, which is mainly used to make tungsten heater. Tungsten twisted wire is a consumable material in vacuum coating. At present, it is widely used in picture tube, mirror making, mobile phone and all kinds of plastic, organic matter and metal matrix and all kinds of decoration surface spraying industry.
Due to their high temperature stability, good thermal conductivity, corrosion resistance and flexible shape design, tungsten and molybdenum crucible as well as tungsten and molybdenum boats are widely used in the vacuum coating industry to carry, heat and evaporate the key components of coating materials. Suitable for loading, heating and evaporation of coating materials.
