Characterised by the highest chemical purity and transparency. For more than 50 years it has been successfully used for the production of quartz tubes of various diameters, quartz blanks and quartz crucibles for the solar and semiconductor industries. Quartz concentrate, SiO2 content -97,0-99,0%. Appearance: white-grey powder. Particle size: from 0.025 to 0.100 mm. Quartz concentrate of FQ-6KP grade can be used: -For the production of construction mixtures as a filler that improves the strength characteristics of mixtures; - For the production of abrasives; - In metallurgical industry as flux and slag-forming additives; - For the manufacture of refractory products (electrodes for welding, bricks, mortars); - As fillers for colouring and adhesive mixtures, putties.
