CAS             NO. :  14987-04-3

EINECS         NO. :  239-076-7



This product is a hydrated magnesium silicate with variable composition. Due to the openness of its crystal structure, magnesium trisilicate contains interconnected holes and channels that are connected to the outside. It has a well-developed pore structure and a large specific surface area, resulting in good adsorption performance, ion exchange, and molecular sieve function. It has broad application prospects in pharmaceutical intermediates, food additives, rubber fillers, deodorizers, ceramics industry, environmental science, and other fields. At the same time, the acidic positions appearing on its skeleton give it solid acidic properties, making it an effective solid catalyst and carrier.

Production Technology

Firstly, industrial magnesium oxide and industrial sulfuric acid, industrial sodium hydroxide and industrial sodium silicate are used as to react and generate magnesium sulfate aqueous solution and sodium silicate alkaline aqueous solution. Then, the magnesium sulfate aqueous solution reacts with the sodium silicate alkaline aqueous solution to form a white precipitate. Finally, the obtained precipitate is filtered and dried to get amorphous magnesium trisilicate.

Features

Our factory uses high-quality industrial magnesium oxide, sulfuric acid, sodium hydroxide, and sodium silicate as starting materials, greatly reducing the content of arsenic, lead, iron, heavy metals, etc. in the products, and there is no introduction of sodium in the production process, ensuring that the products have excellent chemical properties.

Relying on our mature production process and more than 30 years of industrial production experience, in the later stages of production processes such as refining and drying, it is ensured that the product has a smaller bulk density, a larger specific surface area and a good fluidity, thereby possessing better physical properties.

Application

Magnesium trisilicate is widely used in the food industry, ceramics, and rubber industry. In the food industry, magnesium trisilicate is used as an anti caking agent, filter aid, and coating agent, and as a filler in dairy products. It can also be used as a deodorizer and decolorizer. In addition, Magnesium trisilicate is an excellent building material commonly used in the manufacture of lightweight partition panels, soundproof panels, fireproof panels, and sound-absorbing panels. Furthermore, magnesium trisilicate is widely used in the agricultural field. It can serve as a soil amendment to improve soil structure and increasing soil fertility. Moreover, magnesium trisilicate can be used in fertilizer manufacturing, such as silicon potassium fertilizer, silicon calcium fertilizer, etc., to improve crop yield and quality. On top of that, magnesium trisilicate has been applied in the field of environmental protection. It can adsorb heavy metal ions and organic pollutants in water, playing a role in purifying wastewater.
