High Level Product Silicon Calcium

A method for in situ preparation of microporous hard silicon calcium thermal insulation materials involves placing all raw materials for synthesizing hard calcium silicate directly in a mold for a static hydrothermal reaction, thereby directly producing the product, simplifying the process and improving product quality, which is beneficial for the preparation of large, irregular, and ultra-light products. The products made by this method are widely used in industrial fields such as petrochemicals, power generation, metallurgy, and building materials.

1.A type of soluble silicon-calcium-magnesium fertilizer, the raw materials and weight percentage content of the silicon-calcium-magnesium fertilizer are: water-quenched steel slag 60-70%; light-burned magnesium 4-12%; silicon slag 10-20%; diluted sulfuric acid 15-20%; brine 1-3%. This invention turns waste steel slag into a treasure, reduces the land occupied by waste steel slag, and also reduces the environmental pollution caused by steel slag. The silicon-calcium-magnesium fertilizer produced from waste steel slag and other substances has a high content of trace elements, providing crops with a large amount of silicon, calcium, magnesium, manganese, boron, iron, and other trace elements. Additionally, this product's raw material ratios can be adjusted based on the demands for macro and trace elements in different regional soils and crops. Applying this invention can significantly increase the yield and quality of rice, corn, wheat, cotton, soybeans, peanuts, as well as vegetables and fruits, improving their resistance to diseases, pests, and lodging. It is an ideal compound fertilizer for agriculture.
