Product Description

I. Product Overview

The enhanced high-temperature stable crystalline silica micro powder is a high-performance inorganic non-metallic material processed through special techniques. Using high-quality natural quartz as the basic raw material, with the help of advanced processing technologies and formula optimization, while maintaining the inherent characteristics of crystalline silica micro powder, it significantly improves its stability and comprehensive performance in high-temperature environments.

II. Core Performance Advantages

(I) Outstanding High-temperature Stability

1. High Thermal Stability: This product can maintain the structural integrity and the stability of physical and chemical properties in an extremely high-temperature environment of up to [X] °C. Under such high temperatures, there will be no obvious phase transition or decomposition in its crystal structure, ensuring reliable application under high-temperature working conditions.
2. Strong Thermal Shock Resistance: During the thermal cycle process of rapid heating and cooling, the enhanced high-temperature stable crystalline silica micro powder demonstrates excellent thermal shock resistance. It can effectively resist the thermal stress generated by the sharp temperature change, reduce the generation and expansion of internal cracks in the material, and significantly increase the service life of the product in a thermal shock environment.

(II) High Purity and Fine Particle Size

1. High Purity Assurance: Through a series of advanced purification processes, including iron-free grinding, multi-stage acid washing, and precise filtration, etc., it is ensured that the content of silicon dioxide (SiO2) in the product reaches above [specific high purity value], and the contents of heavy metals (such as FeO3, Al2O3, etc.) and other impurities are strictly controlled at an extremely low level. High purity not only improves the chemical stability of the product but also lays a solid foundation for its application in high-end fields.
2. Precise Particle Size Control: The particle size distribution of the product can be precisely controlled. The D50 (median particle size) is usually within the [specific particle size range], and products with narrow distribution or multi-peak distribution can be customized according to the specific needs of customers. Fine and uniform particle size helps to improve the filling performance and dispersibility of the product in composite materials, thereby optimizing the performance of the overall material.

(III) Enhanced Mechanical Properties

1. High Strength: Through special surface treatment and structural optimization, the enhanced high-temperature stable crystalline silica micro powder can effectively transfer stress in composite materials and enhance the strength of the matrix material. The composite materials added with this product have significantly improved mechanical properties such as tensile, bending, and compression, and can meet the engineering applications with high requirements for material strength.
2. High Hardness: The product itself has high hardness, which can enhance the wear resistance and scratch resistance of composite materials. In some environments where friction and wear need to be endured, using materials containing this crystalline silica micro powder can significantly extend the service life of components.

III. Application Fields

(I) High-temperature Industrial Kilns

1. Kiln Lining Materials: As an important part of the kiln lining, the enhanced high-temperature stable crystalline silica micro powder can improve the high-temperature resistance, thermal shock resistance, and mechanical strength of the lining material. It can effectively reduce the erosion and damage of the lining at high temperatures, reduce the maintenance frequency, and improve the operation efficiency and service life of the kiln.
2. Thermal Insulation Material Filling: When used in high-temperature thermal insulation materials, it can improve the high-temperature stability and thermal insulation effect of the thermal insulation materials. In a high-temperature environment, it maintains good thermal insulation performance, reduces heat transfer, and lowers energy consumption.

(II) Electronic Packaging

1. Packaging of High-power Electronic Devices: In the packaging of high-power electronic devices, this product can effectively dissipate the heat generated by the devices. At the same time, with its excellent high-temperature stability, it ensures that under long-term high-temperature working conditions, the bond between the packaging material and the electronic device is firm, and the packaging will not fail due to thermal stress, guaranteeing the stable operation of the electronic device.
2. Aerospace Electronic Equipment: The electronic equipment in the aerospace field often faces extreme temperature environments. The enhanced high-temperature stable crystalline silica micro powder used for the packaging of such equipment can meet its strict requirements for materials in terms of high temperature and high reliability, and improve the working performance and reliability of the electronic equipment in complex environments.

IV. Summary of Product Advantages

1. Excellent Performance: It performs outstandingly in aspects such as high-temperature stability, mechanical properties, purity, and particle size control, meeting the stringent requirements of various high-end application scenarios.
2. Advanced Process: Adopting advanced production processes and a strict quality control system to ensure the stability and reliability of product quality.
3. Customized Services: Customized product solutions can be provided according to the different needs of customers to meet diverse application requirements.
4. Environmental Protection and Sustainability: Paying attention to environmental protection during the production process, adopting clean production technologies to reduce the impact on the environment, and conforming to the concept of sustainable development.
