Overview of Silica aerogel granule specialized in ing nano aerogel powder
Aerogels are ultralight, highly porous materials known for their exceptional insulation properties, remarkable low density, and incredible strength-to-weight ratios. Often referred to as “frozen smoke” due to their ethereal appearance, aerogels are produced by replacing the liquid component of a gel with gas, typically through supercritical drying, which avoids collapse of the gel structure. Composed primarily of air (up to 99.98%), these materials exhibit a wide array of unique characteristics that make them valuable across various industries.

Parameters of Silica aerogel granule specialized in ing nano aerogel powder
Silica aerogel granules and nano aerogel powders represent cutting-edge materials with unique properties that make them indispensable in various industries including electronics, construction, and aerospace. These materials are characterized by their high porosity, low density, and exceptional thermal insulation capabilities.
The silica aerogel granules are typically composed of micro- or nano-sized particles of silica that have been processed to remove the liquid solvent, leaving behind a porous structure that retains the original gel’s framework. This results in a material that is lighter than air yet incredibly strong and durable. The granule size can range from micrometers to nanometers, offering a versatile range of applications.
On the other hand, nano aerogel powders are finely divided silica aerogel particles that can be dispersed in liquids or used in dry forms. These powders offer the advantage of being easily incorporated into existing systems or processes, making them ideal for use in composite materials, coatings, and as catalyst supports. Their small size allows for enhanced surface area and reactivity, which is beneficial in numerous industrial applications.
Key parameters for these materials often include:
1. **Density**: Typically, silica aerogels have densities ranging from 0.1 to 0.2 mg/cm³, significantly lower than most conventional materials, making them highly suitable for lightweight applications.
2. **Thermal Conductivity**: Due to their low density and open pore structure, silica aerogels exhibit extremely low thermal conductivity, often less than 0.025 W/m·K at room temperature. This makes them excellent insulators, ideal for thermal management in electronics, building insulation, and heat-resistant clothing.
3. **Mechanical Properties**: Depending on the processing conditions, silica aerogels can show a wide range of mechanical properties. They can be brittle like glass or exhibit rubber-like elasticity, depending on their structure and composition.
4. **Chemical Stability**: Silica aerogels are highly chemically inert and resistant to most acids, bases, and solvents. This stability makes them suitable for use in harsh environments and in applications where chemical resistance is critical.
5. **Reactivity**: The large surface area of nano aerogel powders makes them highly reactive, which can be advantageous in catalytic applications where surface area directly impacts reaction rates.
6. **Optical Properties**: Silica aerogels can be transparent, translucent, or opaque, depending on their structure and composition. This property is particularly useful in optical devices and solar energy applications.
In conclusion, silica aerogel granules and nano aerogel powders offer a unique combination of properties that make them valuable in a wide range of industries. Their development continues to push the boundaries of what is possible in materials science, opening up new possibilities in technology, energy efficiency, and environmental sustainability.

FAQs of Silica aerogel granule specialized in ing nano aerogel powder
Q: Is Silica aerogel granule specialized in ing nano aerogel powder fragile?
A: Traditional aerogels are brittle and fragile; however, advancements have led to the development of “flexible” or “rigid” aerogels that maintain their unique properties while being more durable.
Q: How is Silica aerogel granule specialized in ing nano aerogel powder made?
A: Silica aerogel granule specialized in ing nano aerogel powder is synthesized by replacing the liquid in a gel with gas without causing the structure to collapse. This is typically achieved through supercritical drying, where the solvent is converted to a supercritical state, allowing it to evaporate without forming liquid-gas interfaces that could damage the gel structure.
Q: Is Silica aerogel granule specialized in ing nano aerogel powder expensive?
A: Historically, aerogels have been costly due to their complex manufacturing process. However, with technological advancements and economies of scale, costs are gradually decreasing.
Q: Can Silica aerogel granule specialized in ing nano aerogel powder conduct electricity?
A: Most aerogels are poor conductors of electricity due to their porous, insulating nature. However, certain metal-oxide aerogels can display semiconducting or even conducting properties.
Q: Is Silica aerogel granule specialized in ing nano aerogel powder environmentally friendly?
A: Aerogels themselves do not pose environmental hazards, and their use in insulation can reduce energy consumption. However, the production process may involve chemicals that require careful handling and disposal.
