Hollow glass balls are hollow spherical powdered materials that are non-metallic and inorganic. Their particle size is 5-100mm with a wall-thickness of 1-2mm. The compressive strength ranges from 3-125MPa.
The following is a list of the most recent articles about Hollow Glass Beads Sphere Hollow Glass Beads : 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 foam or lightweight cement. 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 have low density, and they’re resistant to heat and chemicals. 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 hollow ball. This is expected as the greater density of the sphere increases the compressive strengths. Hollow glass sphere Chemically stable, nonflammable, and nonporous. Excellent water resistance. It is a trusted worldwide brand.

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 can you tell? Hollow Glass Beads Sphere Hollow Glass Beads Produced?
How do you make microspheres of glass?
1. Glass powder method
The glass powder method involves passing pre-prepared powdered glass containing SO3 through the flame between temperatures of 1100-1500. Due to the increase in the solubility, and change in atmosphere of the kiln at this point, SO3 as well as other gases dissolved into the glass are forced out of the interior of the powder. Surface tension causes the glass powder to become spherical at high temperature. 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 a special auxiliary (boric, urea or ammonium pentaborate), aqueous sodium silicate solution, and then by the nozzle into the solution injection to the spray-dryer, it is expected to fall after drying, to obtain a specific particle size of powder, the final product will be a powder particle heating foam forming hollow glass beads.
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 =2) and 10% ammonium aqueous solution. After evenly mixing, the hollow beads are sprayed onto the spray dryer tower.
4. Dry gel method
The alkyl sodium was added to dilute the hydrochloric and it decomposes with water. After gelation, gel was dried twice at 60°C and 150°C and then crushed in a ball mill. 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, buoyancy in deep sea, bowling material, sealing material and lightweight. They are also used by the electronic industry for lightweight packaging, as well as resin handicrafts.
Hollow glass microspheres are also coated to provide a conductive surface. These coatings, which are of optimal thickness, provide spherical materials with excellent shielding and conducting properties. They also maintain the weight savings that come with hollow low-density material. These conductive microbubbles can be used in military applications, biotechnology and medical devices as well electronics.
Hollow glass beads can reduce weight and improve sound insulation. The products are also resistant to cracking and have a good reprocessing ability. It is used in the manufacture of composite materials like wood, engineering plastics, rubber, FRP and artificial marble.
