What material is Silicon dioxide
What's Silicon dioxide?
You can find the
The silicon atom, crystal, is at the centre of the regular trihedron. Four oxygen atoms, on the other hand, are at the vertices. The oxygen atoms located at the vertices connect many of these tetrahedrons. Each oxygen atom has two silicon atoms.
SiO2 represents silicon dioxide in its simplest form. But SiO2 cannot be described as a simple molecular structure. Instead, it is the ratio between the number of silicon atoms and the oxygen present within the silicon dioxide crystal. A pure, natural silica is an insoluble, hard, transparent and colorless solid that's often used for optical instrument manufacturing.
Silicon dioxide production method
Preparation of amorphous Silica involves five steps: preparation of silica gel; granulation and sintering processes; cleaning and drying.
1: Making silica gel
It is necessary to have all the materials prepared.
2: The Granulation Process
Once the silica gel has dried, the powder can be pulverized into powder and classified according to its particle size.
Sintered silicon dioxide powder from the granulation is at 800 °C to 1450 °C. Thermal plasma is then used for the introduction of argon gas at a preset flow rate, as well as to produce plasma at a specified high-frequency output power. At a preset supply rate, place the silicon dioxide powder obtained during the sintering into the plasma torch. Then heat it and allow it to melt at temperatures between 2000 C and the boiling point.
Step 4: The Cleaning Process
The fine powder that remains on the surface of the spheroidized silicon powder should be removed after .
5: The drying process
Following the above cleaning procedure, allow the silica to dry.
Crystalline silica preparation method
You will need to mix the silica dioxide, water, structure-directing, alkali or acid into the mixture. After it has finished, you can cool the reactor to 100-220degC. Keep it there for at least 5 to 10 hours.
Silicon dioxide Applications
Silica is used as a raw material to manufacture glass, quartz, water, and optical fibres.
The silicon dioxide crystallizes after it has been silica gelated and dried. It then becomes a crystal.
Silica can be used to lubricate and promote flow. This is a combination of a lubricant agent, an antisticking agent, as well as a flow enhancer. This is a good choice for the granulation oil and extracts. It has excellent fluidity and compressibility. This can be used in direct compression as well. This disintegrant can improve the fluidity and bulk density of granules as well as the tablet's hardness. It also reduces the time it takes to disintegrate the drugs.
Silicon dioxide price
Particle size, purity and cost will all affect product prices. Purchase volume also has an effect on particle size. Large quantities of small amounts will result in a lower price. Our company website provides information about the cost of each particle size.
