Physical Property: TOP series silica are produced by the way of precipitation,product parameters are controlled automatically, through which different types'
silica can be produced accurately. It also can be produced according to demand. TOP series silica possess density 0.192-0.320, fusion point 1750℃，hollowness.
It has good dispersancy in crude rubber with property of quick mixing and high intensity. It can be used in many fields, and it is easy to combine with fibres, rubber and plastics etc.
Silicon Dioxide exists in two main forms: Crystalline Silicon Dioxide and Amorphous Silica. Crystalline Silicon Dioxide, like quartz, has a well - ordered atomic structure, which gives it high hardness and excellent optical properties. It is transparent to a wide range of wavelengths, making it useful in optical applications.
Amorphous Silica, on the other hand, lacks a long - range ordered structure. Fused Silica, a type of amorphous silica, is made by melting quartz and has extremely low thermal expansion, making it ideal for high - precision applications. Silicon Dioxide Nanoparticles have unique properties due to their small size, such as a large surface - to - volume ratio, which can enhance reactivity in chemical processes.
Silica Powder and Silicon Dioxide Powder come in various particle sizes and purities. Their physical forms can range from fine powders to granular materials, which can be tailored according to different application requirements.
Is mainly used barite as material which containing high components of barium sulfate barite, coal and calcium chloride is mixed, and calcined to get barium chloride, reaction is as follows:
BaSO4 + 4C + CaCl2 → BaCl2 + CaS + 4CO ↑.
Production method of Barium Chloride anhydrous: Barium chloride dihydrate is heated to above 150℃ by dehydration to obtain anhydrous barium chloride products. its
BaCl2 • 2H2O [△] → BaCl2 + 2H2O
Barium chloride can be also prepared from barium hydroxide or barium carbonate, the latter being found naturally as the mineral “Witherite”. These basic salts react to give hydrated barium chloride. On an industrial scale, it is prepared via a two-step process

* TOP25 type Silica, which belongs to Alkaline White Carbon Black, can be used as reinforcing agent in the field of butyl rubber products such as rubber tubes, tapes, rubber seals and other rubber products. It can enhance the physical properties of rubber such as strength, hardness, tear strength, elasticity and wear resistance, making rubber products more durable and improving their performance and reliability.
There are two main ways to produce Silicon Dioxide: natural extraction and synthetic methods.
Natural Extraction
Natural quartz is mined from the earth. After extraction, it undergoes a series of processes such as crushing, grinding, and purification to obtain high - purity Silicon Dioxide. This process mainly produces crystalline forms of silicon dioxide.
Synthetic Methods
Synthetic Silicon Dioxide is produced through chemical reactions. One common method is the precipitation process, where sodium silicate reacts with an acid to form a silica gel, which is then dried and milled to produce silica powder. Another method is the fumed silica process, which involves the high - temperature hydrolysis of silicon tetrachloride in an oxygen - hydrogen flame to produce extremely fine and high - purity amorphous silica.

In the Tire and Rubber Industry
Silicon Dioxide in Tires and Silicon Dioxide in Rubber play a crucial role. Silica Filler is added to rubber compounds to improve tire performance. It enhances traction, reduces rolling resistance, and improves fuel efficiency. This makes tires safer and more environmentally friendly.
In the Electronics Industry
Silicon Dioxide in Electronics is used as an insulating material in semiconductor devices. Its high dielectric strength and thermal stability make it an ideal choice for isolating different components in integrated circuits. It also helps to protect electronic components from environmental factors such as moisture and dust.
In the Food Industry
Silica in food is used as an anti - caking agent. It prevents food products from clumping together, ensuring a free - flowing consistency. It is commonly used in powdered food products such as spices, flour, and coffee creamer.
In the Paint Industry
Silica in Paints is used to improve the durability and scratch resistance of paint coatings. It can also enhance the gloss and appearance of the paint, making it more appealing to consumers.
In the Pharmaceutical Industry
Silicon Dioxide in Pharmaceuticals is used as a glidant in tablet manufacturing. It helps the tablets to flow smoothly during the production process, ensuring consistent tablet weight and quality.
