Hollow glass balls are hollow spherical powdered inorganic nonmetallic materials. Their particle size is 5-100mm with a thickness of 1-2mm. The compressive strength is 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 microspheres with a range of diameters from 10 to 30 micrometers. Hollow spheres fill composite materials like lightweight concrete or syntactic 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 of the material 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 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 density of the hollow ball, the stronger the compression strength. 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 multi-functional and have excellent fluidity, chemical stability.

What are 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 a flame heated between 1100-1500°C. Due to the increase in solubility, SO3 as well as other gases in the glass are released from the inside due to the change in atmosphere. 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 Method
The spray granulation is done in advance using a special auxiliary reagent, such as ammonium pentaborate, urea or boric acid. After the solution has been injected, it is expected that the powder particles will drop to a specified size after drying.
3. The droplet method
The liquid drop technique uses the same raw material as the spray-granulation method. The same amount of 10% ammonium-perborate aqueous solutions is added to 500 copies sodium silicate (M(SiO2):M (Na2O =2) as the raw materials. After evenly mixing, the hollow beads are sprayed onto the spray dryer tower.
4. Dry gel method
Alkylsalts are added to hydrochloric acid to dilute it and they decompose in water. The 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 at 1280 in a vertical electric oven.

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, low-density concrete, bowling material, 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, lightweight concrete.
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, but still maintain the weight savings of hollow low-density material. 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 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.
