@Ryan-lc4bl
Жыл бұрын
Probably because it has one of the highest melting points of any common metal (around 3400°C). So, it's almost impossible to cast it as solid block, rather tungsten powder/granules are sintered (pressed into a mold at high pressure/at it's melting point), and the granules can fuse together due to their high surface area, into a "solid" sintered block. Oddly enough, tungsten has also nearly the same density as pure gold (19.3g/cm³)

@@Ryan-lc4blInduction levitation furnace should work, though, in a near-vacuum (just high enough pressure to keep it from depositing too strongly onto the induction coil (a vaguely funnel shaped copper pipe spiral)), magnetic-levitation-based squeezing a drop out of the ball of molten tungsten that splashes down into the mold, and feeding solid tungsten in via perhaps powder suspended in (part of) the gas stream around. Or just arranging for no gas convection currents that cause problems with dropping/raining controlled-particle-size granules (i.e., sand-tier coarseness (not dust-tier!) "powder") from the top into the molten blob and waiting long enough for them to dissolve into the surrounding molten blob before squeezing any further/new drops out. Not sure how it'd interact with the levitation/melting field (it's shaped to cause the desired levitation at a power level/amplitude that works well for the desired melting/compensating black body radiation (it's a deformed sphere shaped blob of "light bulb", running so hot it burns out ~instantly (thermal mass would be negligible if it'd be light bulb filament shaped)!)/compensating for convective cooling by required residual gas (need to block the tungsten vapor that'd sublimate/boil off in good vacuum, by placing gas molecules in the way)), but feeding tungsten wire (somewhat) continuously down into the blob may work and would simplify the dropper/feeder mechanism. Alternatively, given that levitation increases with conductivity of the feed, and metals decrease in conductivity with temperature, reduced-power insertion of a block of solid tungsten (sintered to sufficiently decent conductivity) by means of a gripper/tongs, or even just a pedestal raising it into the coil from below (doesn't matter whether the coil or the pedestal moves), should work just fine at the expense of not operating anywhere near continuously w.r.t. the dripping. Taking the success of hal-01336015 , and substituting from aluminium for tungsten assuming 19g/ml and 150W/cm^2 radiative cooling at 3000C, the initial 7.5cm diameter ball they simulated with would be 4.2kg and radiating only 26.5 kW. While substantial, it feels/sounds low enough to not be too high, given that the coils used in the HAL paper claim a current of 1.1 kA eff each (assuming 3 turns, 3cm radius, 5cm length solenoid as each coil, which should low-ball given the ferrite core/yoke increasing this beyond those air-values, this is 0.64 uH per coil, with each coil pair series connected, 1.28 uH per pair), which at 30 kHz gives 241 V and at 40 kHz 322 V (effective, in resonant tank with the specified current and frequency). The current ought to scale up for tungsten due to the higher mass, assuming linear (corresponding to motors usually having a linear relationship between current and torque/force) to mass, to about 8.4 times that paper's values. Given that power scales quadratically with current, this would be about 70 times as much heating power. So only about 380 W of radiative-cooling-equilibrium heating power when scaling the numbers back down to the aluminium situation. And that's tiny compared to the resonance's apparent power of 619 kW (well, technically "kVA") that neglected the ferrite yoke (so reality ought to be higher). Together, this suggests that a much larger blob of tungsten could be melted when scaling the HAL paper up, making use of that tungsten has on the order of 9 times more diameter at radiation vs. levitation power equilibrium than aluminium, giving a massive 3 tons assuming the aluminium approach of the HAL paper has a scaling limit at the 500g system they designed.... just at roughly 1 MW of power consumption for radiation/levitation (total system losses are much higher, as this only considers those in the ball of tungsten, not the coils/generators).

Cost and density are limiting factors. Refractory metals find uses in high temperature technical components such as turbines, but ideally you'd want those to be as low mass as possible so lower density refractories like Tantalum and Molybdenum are used. Tungsten is also pretty pricey so for any application where its extreme properties are not absolutely necessary, alternatives will be found.

Tungsten chemistry is nice, and quite accessible. And quite safe compared to other metals since tungsten isn't toxic. I have made tungsten blue by reducing peroxopolytungstic acid with ascorbic acid (vitamin C) in a slightly alkaline solution. The peroxopolytungstic acid itself I made by dissolving tungsten metal (from a broken TIG electrode) in 30% hydrogen peroxide.

try coating objects inside the reaction tube, also try copper foil exfoliation with zinc + cuso4/h2so4 bath long time (minutes) dip, how about aluminium surface coating by termite replacement reaction, ie aluminium takes places of the hydrogen gas, and takes the oxygen/chloride from the tungsten compound, aluminium chloride will sublimate off and leave tungsten surface on top, which will no longer react, should also only need about 300C of WCl6 melting, to get the termite replacement reaction going. zinc should work for the replacement reaction too, at heat.
