Overview of Hydrophobic Excellent Thermal Insulation SiO2 Silica 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.
Features of Hydrophobic Excellent Thermal Insulation SiO2 Silica Aerogel Powder
-
Extremely Low Density: Aerogels are some of the world’s lightest solids, with densities as low as 0.001 grams per cubic centimeter.
-
Superb Insulation: They possess extremely low thermal conductivity, making them among the best insulators known to man, effective at temperatures from -270°C to 1,000°C.
-
High Porosity: With a porous structure that can reach up to 99.9%, aerogels have an incredibly large internal surface area, enhancing their functionality in absorption and catalysis applications.
-
Translucent to Transparent: Depending on their composition, aerogels can transmit light, giving them a unique semi-transparent or transparent appearance.
-
Mechanical Strength: Despite their fragile appearance, aerogels can be engineered to possess significant mechanical strength, capable of bearing considerable weight.
-
Chemically Inert: Many aerogels are chemically stable and resistant to corrosion, making them suitable for harsh environments.

Parameters of Hydrophobic Excellent Thermal Insulation SiO2 Silica Aerogel Powder
The SiO2Silica Aerogel powder is a unique thermoplastic material that is highly effective in thermal insulation due to its high water content and low melting point. The powder is made up ofSiO2 silicate particles that are mixed together to form a fine powder.
One of the main advantages of this material is its excellent thermal insulating properties. When heated, the SiO2Silica powder undergoes thermal expansion, which reduces heat loss to the surrounding environment. This property makes it well-suited for use in applications where there is a need to control heat transfer through the space or atmosphere.
Another advantage of SiO2Silica powder is its high visco-index. This means that it has a relatively low coefficient of vaporization, making it less prone to degradation over time. This property is particularly important in applications where temperature sensitivity is critical, such as temperature-controlled systems in industrial processes or medical equipment.
Additionally, SiO2Silica powder is relatively easy to form and use, making it a versatile material for a wide range of applications. It can be used in a variety of industries, including aerospace, automotive, construction, and electronics.
Overall, SiO2Silica powder is an excellent material for thermal insulation due to its high water content and low melting point, excellent thermal insulating properties, and flexibility in use. Its versatility and ease of use make it a popular choice for a wide range of applications, from heating and cooling systems to electrical transmission lines and construction materials.

FAQs of Hydrophobic Excellent Thermal Insulation SiO2 Silica Aerogel Powder
Q: Is Hydrophobic Excellent Thermal Insulation SiO2 Silica 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 Hydrophobic Excellent Thermal Insulation SiO2 Silica Aerogel Powder made?
A: Hydrophobic Excellent Thermal Insulation SiO2 Silica 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 Hydrophobic Excellent Thermal Insulation SiO2 Silica 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 Hydrophobic Excellent Thermal Insulation SiO2 Silica 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 Hydrophobic Excellent Thermal Insulation SiO2 Silica 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.
