The crystal silica

This toxic substance can inflame the lung and cause severe inflammation, such as silicosis or bronchitis. It also causes systemic autoimmune disorders like lupus, rheumatoid, and lupus. Amorphous silica may cause temporary inflammation in the lungs. However, all symptoms can be treated.

Amorphous silica is formed by long-range arrangements of oxygen and silicon atoms. A silicon dioxide crystal has four oxygen atoms at its four corners. The silicon atoms will be at the centre of a regular trihedron. Numerous tetrahedrons can be held together with oxygen atoms located at their four corners. The two tetrahedrons that share an oxygen atom are called a tetrahedron. This means each oxygen-atom is bound to two silicon molecules.

Silica’s molecular formula is its simplest.

SiO2

SiO2 doesn’t represent a simple molecular (just the ratio among the silicon atoms and oxygen atoms of silica crystals). A pure crystal of natural silica is insoluble, hard, translucent, non-colorless, transparent and colorless solid that’s often used for the manufacturing of optical instruments.

Amorphous silicon dioxide preparation method

Preparing amorphous silica involves five steps: preparation of silica gel; sintering and cleaning; drying process.


1. Silica gel preparation


Silica gel is made from silicon tetrachloride. Pulverizing organic silicon compounds, such as tetramethoxy siloxane, can also produce it. Fumed silica, however, can make silica gel.


2. Granulation Process


A silica powder can be made by dry drying silicone gel and then grinding the powder.


3. Insintering


Silica powder from the granulation is heated to 800 to 1450 degrees C. Thermal plasma can be spheroidized to release argon at a preset flow rate. The output is then converted at a specified frequency in order to create plasma. Plasma torch: The sintered silica is heated to 2000°C, which will melt it.


4. Cleaning


The surface adhering fine powder to the silica powder after spheroidization is completed.


5. Drying


Following the above process, silica powder should be dried.


Silicon Dioxide Uses:


Silica is used in the manufacture of many products.

silicon dioxide glass

Quartz glass, Water glass, Optic Fiber, are all important elements of the electronic industry. These include optical instruments, handicrafts, refractory material, and an important component for scientific research.

1. Most glass is made from silica. If silica is melted with other minerals, the freezing points reduction principle decreases the melting temperature and improves fluidity. SiO2’s glass transition temperature is approximately 1475K. The glass transition temperature of fused SiO2 is about 1475K. Most ceramic glazes consist mainly of silica.

2. Silica is also a good additive.

3. Silica is especially suitable for the granulation and extraction of oils and other extracts.

4. Silicium dioxide, as a disintegrant can significantly improve the fluidity and bulk density of the granules. It also increases the hardness of prepared tablets. You can use it as an internal desiccant to increase the stability of your drug.

5. Silica is also used to thicken liquid preparations, as a defoamer and filter aid.

6. 95% of all silica’s commercial uses are within the construction industry. For example, the creation of Portland cement concrete.

7. Due to its light diffusion and natural absorption, silica has a significant role in cosmetics.

8. For the semiconductor industry, passivating silicon’s surface through thermal oxidation is essential. It’s used to make metal oxide field-effect transistors with MOSFET (metal oxide semiconductor field effects transistors) or silicon integrated circuit chips using planar technology.

9. You can use silica to extract DNA or RNA, as it is able to bind nucleic acids when there are chaotropic agents.

10. Because silicon dioxide can be used as a natural semiconductor oxide instead of other semiconductors, such as indium-phosphide and gallium arsenide, it is much more popular.

11. It is possible to grow silicon dioxide on top of the surfaces of silicon semiconductors. Silicon oxide can protect silicon surfaces during the diffusion process. It can also be used to create a diffusion shield.

12.

Silicon dioxide in food

Food producers use silica as an anti-caking ingredient in creams or spices. This allows for fine powder flow and absorbs moisture.

13.
