Hollow glass balls are hollow spherical powdered non-metallic inorganic materials. Their particle size is 5-100mm with a wall thickness ranging from 1-2mm. The compressive strength ranges between 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? Microspheres are hollow glass balls with a range of diameters 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, a high melting temperature, a high resistivity, a low thermal conductivity coefficient and small thermal shrinkage coefficient.
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 about 10% thicker than their diameter. 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 the density, the higher it will be. 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
In the glass powder method, pre-prepared powdered glass containing SO3 is passed through the flame between temperatures of 1100-1500. Due to the decreased solubility of SO3 in the glass and the changes in atmosphere, the SO3 and other gas dissolved within the glass powder begin to overflow. During high temperatures, the glass becomes spherical because of the surface tension. The spherical glass particles are sealed with the spillage gas to form hollow glass beads.
2. Spray granulation is a method of granulation.
Spray granulation is made with a solution of sodium silicate aqueous containing a special reagent, such as ammonium pentaborate, urea or boric acid. After drying, it is expected that the powder particles will shrink to a specific size.
3. 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 diluted hydrochloric 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, buoyancy in deep sea, bowling material, low density cement, sealing material and lightweight. Other uses include resin handicrafts such as the wall-hanging frame for murals, sandwich-layer structure of lightweight packaging material, electronic industry.
Hollow glass microspheres are also coated to provide a conductive surface. The thinnest possible conductive coatings provide spherical materials with excellent shielding and conducting properties while maintaining weight savings. 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, 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.
