What is Hollow glass powder?
Hollow Glass Microspheres (HGMS) are near-perfect engineered spherical bubbles of thin-walled Glass, approximately 50 microns in size, with a low density of between 0.1-0.4 g/cc. The glass type is amorphous and can come with low-purity or high-purity grades. Hollow glass microspheres achieve high Total Solar Reflectance (TSR) levels in coatings. 3M White Hollow Glass Microspheres K-15, Size: 10-50 Micron at Rs 1201/kg in Mumbai. In contrast, hollow glass microspheres are produced by adding a blowing agent to glass powder [3]. When burned, a blowing agent such as sodium silicate decomposes to multiple gases, causing the microsphere to form a hollow structure.
Where is hollow glass or glass microsphere used?
High-quality spherical glass microspheres are often used in gas plasma, automotive mirrors, electronic displays, flip-chip technology, filters, microscopy, and electronic equipment. Other applications include syntactic foams and particulate composites, and reflective paints. However, glass dust is classified as amorphous silica dioxide. This type of silica poses no health risks. Glass typically has a tensile strength of 7 megapascals (1,000 psi). However, the theoretical upper bound on its strength is orders of magnitude higher: 17 gigapascals (2,500,000 psi). This high value is due to silicon dioxide's strong chemical Si–O bonds. Hollow Glass Microspheres, also called bubbles, microbubbles, or micro balloons, are typically made from a borosilicate-soda lime glass blend formulation and provide the benefits of low density, high heat and chemical resistance.
How are hollow glasses made?
Mouth Blown Process shapes Molten Glass. Molten Glass (Gob) is removed from the furnace with the help of cast iron rods and blown, and more Glass is gathered and blown/pressed in the desired mould made of wood or metal. This glassware is sent to anneal or remove strains in the chamber. A hollow prism is made using a glass plate with the centre part of the prism vacant. This cavity can be filled with gas or other fluids. Thus, a hollow prism is also called a fluid prism. Glass tubes are mainly cylindrical hollow wares. Their special shape, combined with the huge variety of glass types (like borosilicate, flint, aluminosilicate, soda lime, lead or quartz glass), allows the use of glass tubing in many applications. First, recycled Glass is manually pulverised with a mortar and pestle into a fine powder. After adding ceramic dyes, the powdered glass mix is poured carefully into clay moulds. A cassava stalk in the centre creates a hole in the bead. Then, the prepared moulds are fired in a kiln.
