Update 10.15 Good Price High Purity Hydrated Silica White Carbon Black Sio2 Precipitated Silicon dioxide for Industrial Use
Product Description
Silicon dioxide is an inorganic compound that is widely found in nature and can also be artificially synthesized. Its chemical formula is SiO2. It is one of the main components of the Earth's crust and also a basic material with extremely wide applications in industry and daily life.
Physical Properties: The particles are extremely fine (with a particle size usually ranging from 5-100nm), having a large specific surface area and strong adsorption capacity; they are insoluble in water and most organic solvents, and exhibit good high-temperature resistance and chemical stability.
Functional Properties: They have excellent functions such as reinforcement, thickening, anti-adhesion, and anti-settling, and can improve the mechanical strength, stability, and processing performance of products.

Application
Silicon Dioxide Application:
Construction and building materials industry: It is a core raw material for cement, glass, and ceramics. Quartz sand is also used in concrete and pavement materials to enhance strength and durability.
Electronics and Semiconductor Industry: High-purity silicon dioxide (such as quartz) is used in the manufacturing of insulating layers for semiconductor chips, optical fibers (the core material for signal transmission), and quartz crucibles (containers for melting monocrystalline silicon).
Field of industrial additives:
1. As a reinforcing agent for rubber and plastics, it improves the wear resistance and mechanical strength of products;
2. As a thickener and matting agent for coatings and inks, it improves leveling properties and coating texture;
3. Food-grade silica can be used as an anti-caking agent (for example, to prevent caking in milk powder and protein powder).
Daily and consumer fields: Crystals and agates are used in jewelry and crafts; silica gel (silica dioxide gel) is used as desiccants, non-slip mats, beauty instrument probes, etc.; silica dioxide added to toothpaste can serve as a mild abrasive.
Packaging & Shipping
Silicon Dioxide Shipping and Packaging:
Packing: Package in 20 Kg bag, also accpet customer OEM packing.
Storage: Keep in a cool, dry, dark location in a tightly sealed container or cylinder.
Silicon dioxide (especially in powder form such as fumed silica) has strong adsorptivity and easily absorbs moisture in the air, leading to caking, which affects its performance (such as rubber reinforcing effect and coating dispersibility).
1. It must be stored in a dry and well-ventilated warehouse, with the relative humidity controlled below 60%, and kept away from water sources (such as water pipes, humidifiers) or humid areas (such as warehouse corners, under windows).
2. When the packaging is damaged, it must be sealed immediately (waterproof tape can be used to seal it or it can be transferred to a sealed container), and the unused powder must be tightly tied at the opening of the packaging bag in a timely manner.
