What’s sphere quartz powder?
After being purified from quartz crystal, spheres of quartz are pulverized and ultrafinely ground from the stone. The powder then undergoes a very high temperature field to instantly change its phase form, crystal form, shape, and state from solid state to liquid state. Amorphous powder is made of irregularly formed angular particles and transformed into regular spherical grains.
This is the primary method for preparing spherical powder quartz.
1. Flame melting is used primarily to mass produce spheroidized quartz dust. It is important that this heating technology does not require a steady temperature field. The temperature range can be easily adjusted and there should be no secondary pollution of quartz powder. This is the ball-forming principle: The high-temperature fire spray gun produces a high temperature flame between 1600 and 2000 degrees. Powder particles become molten when they enter the high-temperature flame area. The heat from the fire is transferred into the powder’s interior. The action of surface tension means that objects tend to remain stable under pressure. Spherical, which is the most stable form, will allow you to create a ball.
2. The local thermodynamic equilibrium (or thermal) plasma is another name for this plasma. The plasma’s principal feature is its close proximity to the surrounding electron, ion and gas temperatures. The thermal plasmas are arc plasma, high-frequency plasma and induction.
This method uses high-frequency plasma to fuse spherical powder. Because it has stable control and a wide temperature range, as well as high output and high spheroidization rates, the method makes more sense. Similar to the flame melting process, the principle and the procedure are identical.
It is made of compressed air and has a 10m3/h working gas volume. High-frequency plasma generators have a 100kW input power, while high-temperature gases of 4000-7000 are generated to heat the system. After the silica is transferred from the top to arc of the plasma reactor furnace via the feeder and melted, the powder can be gasified using heat. The powder is quenched using a special quencher. It can then be collected by gravity and bag dust (nanoscale) within 1s-2s.
3. Chemical Synthesis
To obtain silica sol, heat the silica emulsion with ammonia or ammonium bicarbonate. The gel then undergoes acid treatment to make hydrated spherical silicona. This product has a low uranium level, which is a characteristic. However, it is also easy to agglomerate.
