Cenospheres for Ceramics: Refractories, Tiles, Fire bricks

1. A cenosphere is a lightweight, inert, hollow sphere comprised largely of silica and alumina and filled with air and/or gases. Cenospheres are a naturally occurring by-product of the burning process at coal-fired power plants, and they have most of the same properties as manufactured hollow-sphered products.

2. Typical Properties of Cenospheres

SiO252 - 62%
Al2O332 - 36%
K2O1.2 – 3.2%
Fe2O31 - 2%
TiO20.8 - 1.3%
MgO1 – 2.5%
Na200.2 - 0.6%
CAO0.1 – 0.5%

3. Physical Properties

Bulk Density(KG/M3)350 - 450
Hardness(Moh's)5 - 6
Compressive Strength(Kg/cm2)180 - 280
ColorLight Grey – Light Buff
Melting Point1350C
PH in water6 - 7
Sinkers3% Max
Oil Absorption16-18 G/100G

4.Characteristics :

(1). High refractoriness:
the main chemical composition of the floating beads is silicon and aluminum oxide, wherein the silicon dioxide is about 50-65%, and the aluminum oxide is about 25-35%. Because the melting point of silica is as high as 1725 degrees Celsius, the melting point of aluminum oxide is 2050 degrees Celsius, which are all high refractory materials. Therefore, the floating beads have an extremely high degree of refractoriness, generally reaching 1600-1700 degrees Celsius, making them excellent high-performance refractories.
(2). Light-weight:
thermal insulation; floating beads wall is hollow, the cavity is semi-vacuum, only a very small amount of gas (N2, H2, and CO2, etc.), heat conduction is extremely slow. Therefore, the floating beads are not only lightweight (weight: 250-450 kg / m3), but also excellent thermal insulation (thermal conductivity normal temperature 0.08-0.1), which laid the foundation for its role in the field of lightweight insulation materials.
(3). High hardness, high strength:
because the floating beads are made of silicon-aluminum oxide mineral phase (quartz and mullite) hard glass body, the hardness can reach Mohs 6-7, static pressure strength is as high as 70-140MPa, true The density is 2.10-2.20 g/cm3, so the floating beads have high strength.
(4).the insulation is not conductive:
generally, the resistance of the insulator decreases with the increase of temperature, the floating beads are opposite, the resistance increases with the increase of temperature. This advantage is not available in other insulating materials. Therefore, it can be made into an insulating material with excellent performance.
(5). fine particle size, large specific surface area;
floating beads naturally formed particle size of 1-250 microns. The specific surface area is 300-360g/cm2, which is similar to cement. Therefore, the floating beads do not need to be ground and can be used directly. Fineness can meet the needs of various products.

5. Usage :
(1)refractory insulation materials; such as lightweight sintered refractory bricks, lightweight non-burning refractory bricks, casting insulation risers, pipeline insulation shells, fire insulation coatings, thermal insulation paste, composite insulation dry powder, lightweight insulation wear-resistant glass steel,
(2)building materials; architectural decoration, high-grade paving materials, roof waterproof insulation coating, road engineering, modified asphalt, etc.
(3) Petroleum industry; oil field cementing, pipeline anti-corrosion insulation, submarine oilfield, floating device, oil well drilling mud mitigating agent, oil and natural gas transmission pipeline, etc.
(4) insulating materials; plastic activated fillers, high temperature, and high voltage insulators, etc.
(5)paint industry; paints, inks, adhesives, stealth paints, insulating paints, anti-corrosive paints, floor paints, high-temperature fire retardant paints, interior and exterior wall paints, insulation coatings, floor paints, car putties, putty, etc.;
(6)Aerospace and space development; satellite, rocket, spacecraft surface composite materials, satellite fire protection layer, marine equipment, ships, deep-sea submarines, etc.;
(7)plastic industry; such as automotive trim, instrument panel, appliance casing, fan, speaker, lamps General bearing, castings, gears, structural parts, zippers, pipes, plates, etc.
(8)FRP products: various FRP products, artificial marble, FRP ships, handicrafts, etc.; 9. Packaging materials: transformer potting materials, electronic packaging materials, etc.;

40-60 mesh, 80-120 mesh, 150-200 mesh, 200 or more (PS) and other products.
