Technical Parameters

Product Performance:

This product features high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, and an ultraviolet reflectance ofOver 90% and an absorption rate of over 97% in the infrared band. The device has a low ceramic-forming temperature, good dimensional stability, high mechanical strength, excellent chemical corrosion resistance, particularly high-temperature strength, and self-lubricating properties. It forms a fine dispersed phase in composite materials, thereby significantly enhancing their overall performance. The product itself possesses self-lubricating properties and can be applied in lubricating oils. Silicon nitride, with its high hardness and low sliding friction coefficient, can be used in ceramic wear-resistant composite coatings on metal surfaces.

Application direction:

1. Manufacturing precision structural ceramic components: Such as balls and rollers for rolling bearings, sliding bearings, sleeves, valves, and structural components with requirements for wear resistance, high-temperature resistance, and corrosion resistance, used in industries such as metallurgy, chemical engineering, machinery, aviation, and energy.Surface treatment of metals and other materials Such as molds, cutting tools, turbine blades and rotors for steam turbines, as well as coatings for cylinder inner walls.

2. Preparation of high-performance composite materials: such as metal, ceramic, and graphite-based composite materials, rubber, plastics, coatings, adhesives, and other polymer-based composite materials.

3. Application in high-wear-resistant rubber: Adding 1-3 parts of Si3N4 powder to the main rubber material, which is EPDM (ethylene propylene diene monomer) for bellows, can increase the durability test from 200,000 cycles to over 1 million cycles, improving performance by 5 times.

4. Application of wear-resistant composite plating on metal surfaces: Silicon nitride has high hardness and a low sliding friction coefficient, with mechanical properties superior to other ceramic materials. Compared to metal materials, the room-temperature strength of silicon nitride can be maintained above 800°C, and it still retains considerable strength even between 1200°C and 1400°C. For use in demanding conditions, it is advisable to adopt surface-plated Si3N4 metal composite materials.

5. Applications of Infrared-Absorbing Textiles: Silicon-based nanopowder enhances the conductivity of nylon and polyester. Nano silicon nitride has an absorption rate of over 97% for the infrared波段 absorbed by the human body, making it an **excellent additive for infrared-absorbing ultrafine textiles.

6. Application of Release Agents for Polycrystalline and Monocrystalline Silicon: During the melting and casting of polycrystalline and monocrystalline silicon, release agents are used between the silicon melt and the quartz crucible to prevent adhesion of the molten silicon to the crucible. They also serve as a barrier to ensure the purity of the silicon product.

7. In LED luminescent materials: nano-Si₃N₄ phosphors belong to luminescent materials with individual luminescent centers (cerium Ce³⁺, europium Eu²⁺). Their energy transition process is classified as f-d transition.

8. Applications of nano silicon nitride in other industrial fields: Used in high-performance wear-resistant and high-temperature resistant rubber seals and tires, anti-corrosion and fire-resistant coatings, high-temperature insulating electronic materials, and inorganic ceramic lubricating oils. It can also be applied to structural ceramics and inorganic composite materials.
