  Silicon Carbide metallurgical 90 %

Chemical formula: SiC
Fraction: Silicon Carbide 0-3 mm, 0-10 mm, 0-20 mm
Packing:  25 kg multiply paper bags on palette (1000 kg) shrink-wrap, big bags, in bulk
Usage::Silicon carbide metallurgical 90% is used in metallurgy during melting in electric furnaces like a substitution of ferosilicium because of reaching a better quality of alloys and lower finance / economic demand factor. Further in a production of foundry briquettes and like a basic material for production of grains for refractory products.
Physico-chemical properties: Silicon carbide is produced by reduction of silicon monoxide by carbon, which proceed at temperature 2400°C in electric resistance furnace. Burnt out material is further broken to pieces and crushed to the required grains sizes.

  Silicon Carbide briquettes
Silicon Carbide briquets
Silicon Carbide bricks

Dimensions: SiC briquettes a) 10 cm x 10 cm x 11 cm b) hexagonal shape 9 cm x 10 cm
Trade name types: SiC briquettes NORMAL, SPECIAL, EXTRA
Packing: 1 MT on palette, shrink-wrap
Form: For an effective use of Silicon Carbide and easy manipulation either with automatic and hand batching is the Silicon Carbide delivered in briquettes.
Usage: Using of SiC briquettes in foundries brings desoxidation and cleaning of a liquid alloy, to lenghten modification effect in alloy and to reduce a danger of appearance mistakes in alloy ( bubbles ). This using brings also great economical effects through a possibility of increasing steel part toward raw material consumption.

Silicon Carbide briquettes are possible to produce in different types of characteristics and dimensions according to wish of a customer

Chemical name: SiC

Grain sizes: Silicon Carbide FEPA F 14-1200

Sillicon Carbide mixtures for refractory use: F 14/24, 20/40, 30/90, 60/90, 70/90 etc.

Packing: 25 kg multiply paper bags on palette (1000kg) shrink-wrap, big-bags

Usage: Silicon carbide is used mainly in production of abrasive tools and instruments . There are also another ways how to use it , such as blasting by dry and wet method, production of refractory plates, bricks, refractory cement and cramming mixtures. It could be used also in electrotechnical industry and in production of insulators and lightenning-secure´s production. It is also a good addition to a frame and another saws for stone cutting , as well as an inoculant into epoxide resin for to reduce getting worn.

Physico-chemical properties - Silicon carbide is produced by reduction of silicon monoxide by carbon, which proceed at temperature 2400°C in electric resistance furnace. Burnt out material is further broken to pieces and crushed to the required grains size to FEPA standard norm F classification.

Further our offer contents all grit sizes determined for refractory and concreting purposes. We can produce the unusual types of grit sizes to order. The goods is delivered in big-bags, paper bags or in bulk.


News


Company KORUND BENÁTKY, s.r.o. was established in 2003 as a subsidiary company of KOLTEX COLOR, s.r.o. which took over the plant CARBORUNDUM Electrite, a.s., plant II. - a production of White Corundum and SiC. Production operation was taken over including all technology and including long-time employees of the plant. Production was taken over in full running so that a continuity of deliveries was not disturbed.In the present time sorting lines for White Corundum and SiC are operating. Sorting lines are sat with ball mills, vibrational mills, hammer mills, forming mills and many different sorting machines. Grain is during a production several times magnetized. Production process is permanently checked by production control and internal laboratory. Every individual storage tank is equiped with exit confirmation of laboratory.
