Quartz Filtration
Quartz Wool & Sintered Discs
Quartz Wool
Quartz Wool is made from pure Quartz fibre it displays all the characteristics of Quartz glass
Quartz Wool is available from 10 grams – 1kg bags. Available in:
Ultrafine (2 micron diameter),
Fine (4 micron diameter)
Coarse (9 – 30micron diameter)
Uses include
High temperature insulation, up to 1050 Centigrade (long term exposure). Excellent Heat Resistant insulation
Filtration of high temperature corrosive gases & liquids due to its excellent chemical resistance
Barrier plug for combustion tubes.
Furnace insulation, low thermal shock – high electrical resistivity
Asbestos replacement & low odour
Quartz Filters / Quartz Sinters / Quartz Frits or Fritted Discs
High temperature filtration is possible thanks to Quartz filters, otherwise known as Quartz Sintered discs or Quatz fritted discs/ Quartz Frits.
Quartz filters are used in:
Acid filtration
High temperature filtration
Corrosive Gas filtration
Radioactive filtration
Alkali filtration
Sintered or fritted discs are made from fusing Quartz granules together. Available in the following porosity grade.
| Porosity Grade | Average Pore Size in Microns µm | Uses |
| 00 | 250 – 500 | Liquid & Gas Distribution. |
| 0 | 160 – 250 | Gas distribution & Gas distribution in liquids at low pressureFiltration of very coarse precipitates |
| 1 | 100 – 160 | Coarse Filtration, liquid distribution |
| 2 | 40 – 100 | Fine filtrationMercury filtration |
| 3 | 16 – 40 | Analytical filtration (including work with medium fine preciptitates)Filtration in cellulose chemistry Fine Gas filtration |
| 4 | 10 – 16 | Analytical fine filtrationNon return & stop valves for mercury |

The sizes above are the industry standard, if you require different diameter sizes please contact our office staff for a quotation . Sintered discs can be fused into Quartz tubes, if you require this service please send a drawing with clear measurements so that we may quote you.
Unlike Quartz Wool, Quartz Sintered discs can be fused into tubing to provide a permanent filtering solution. When attached to interchangeable joints it provides an excellent way of providing an interchangeable filtering system.
