About us

Limited liability Scientific and Production Company QUARTZ produces articles of quartz ceramics (kersil) which are widely used in various industries due to high thermal resistance, chemical stability, low thermal expansion, good dielectric properties in combination with sufficiently high mechanic strength.

Area of application:

metallurgy (bowls to teem steel, draw plates, lining elements, pots);

foundry (molds for precision casting, pots);

electric engineering (various insulators);

chemical industry (ampoules, reactors, lining, pots, etc.);

glass industry (feeder accessories for glass-forming machines (bowls, plungers, bushings, goggles), shafts for horizontal toughening lines, agitators, burner blocks, throat covers, tweel blocks, pots);

dentistry (draw plates for casting dental alloys, pots).

Manufacturing processes and application of articles are patented.

Quartz ceramics (kersil) are characterized by:

Bending strength 15-45MPa, apparent density 1,9-2,0 g/cm, open porosity 5-15%, thermal linear expansion coefficient 5,8*10-7, thermal resistance to temperature drop 20-1650^oC , glass attack resistance in low-alkali fluxes. The material has a high diffuse reflectance in the wide spectral region and resistant to UV radiation. Heat conductivity coefficient is 0.6-0.9 kcal/m*h*d, dielectric permeability at frequency 10*10 Hz 3,2-3,6 in temperature range 20-1650^oC. Without temperature drops, the material withstands heating and operation at temperatures up to 1750^oC.
