What is hollow-glass microsphere?
Hollow glass microspheres are also called microballoons. Their diameters range from 10 to 30 micrometers. Hollow spheres fill composite materials like lightweight concrete, syntactic elastomer and foam. The hollow spheres can be used to fill lightweight composite materials like syntactic polymer foam and lightweight concrete.
Hollow glass bead
This is a special type of glass bead that is less dense and has a lower thermal conductivity. It's a new type of micron grade light material, developed in 1950s and 60s. Its primary component is borosilicate. The particle size is 10250mm with a wall thickness 12mm. Hollow glass beads feature high compressive strengths, high melting points, high resistivity as well as low thermal conductivity.
Hollow glass microspheres
Micro balloons (also known as bubbles) are formed from borosilicate and sodium salt glass mixtures. They offer low density, high heat, and chemical resistance. The walls are made of
Glass microspheres
The spheres are typically rigid and around 10% thicker. Spherical particles are available in a variety of densities ranging from 0.06g/C3 to 0.80g/C3, and particle sizes from 5um to180um. The wall thickness determines the compression strength of a hollowed sphere. This is expected as the density and size of the sphere increases.

Hollow Glass Sphere Hollow Glass beads Product Performance:
Hollow glass microspheres consist of hollow glass microspheres at the micron level with a smoothed surface. It is made up of borosilicate, which is the main chemical component. The sphere is hollow and transparent under an electron microscope. Hollow glass beads possess low density, good strength, resistance to acid and alkali, low thermal conductivity and electrical insulation, among other qualities. These new materials are multifunctional, have high chemical stability and fluidity.

How do you make microspheres of glass?
1. Glass Powder Method
Using pre-prepared powdered glass containing SO3 and passing it through a flame between temperatures of 1100-1500 is the glass powder method. Due to the increase in solubility, SO3 as well as other gases in the glass are released from the glass. The surface tension of the glass powder causes it to become spherical at high temperatures. The spillage gas forms hollow glass beads when it is sealed within the spherical particle.
2. Spray granulation is a method of granulation.
Spray granulation is a method that is done in advance using aqueous sodium silicate solution with a special auxiliary reagent, such as ammonium nitrate, urea and boric acid. After the solution has been injected into the dryer, it is expected to fall after drying, to obtain a specific particle size.
3. The droplet method
The liquid drop technique uses the same raw material as the spray-granulation method. The raw materials used are 500 copies each of sodium silicate (M(SiO2):M (Na2O), and the same quantity of 10% ammonium-perborate aqueous solutions is added. After evenly mixing, the hollow beads are sprayed onto the spray dryer tower.
4. Dry gel method
The alkyl sodium was added to dilute Hydrochloric Acid and decomposes with water. After gelation, gel was dried twice at 60°C and 150°C and then crushed in a ballmill. After grading was completed, dried gel powder was obtained. This was then foamed up in an electric vertical furnace at 1280.
Applications
Hollow Glass Beads Sphere Hollow Glass Beads
:
Hollow glass microspheres have many applications, including glass fiber reinforced products, composite foam, artificial wood, compound, atomic-ash, deep sea buoyancy, bowling and low-density concrete. They are also used as sealing materials, lightweight, resin, handicrafts, wall plates sandwich layer structure, lightweight packaging materials for electronic industry, lightweight concrete or emulsion explosive.
Hollow glass microspheres are also coated to provide a conductive surface. Conductive coatings optimized in thickness give spherical materials excellent shielding and conducting properties while retaining the weight savings of hollow, low density materials. These conductive microbubbles can be used for military, biotechnology, electronic, and medical applications.
Hollow glass beads can reduce weight and improve sound insulation. The products are also resistant to cracking and have good reprocessing properties. It is used in the manufacture of composite materials like wood, engineering plastics, rubber, buoyancy materials, FRPs, artificial marbles, man-made stones, the oil and gas industry, aerospace and communications, new high-speed cars and ships, thermal insulation coatings and adhesives.
