Turkey
Manufacturer/ Producer
We are as Nigtas Micronized Calcite Trade and Production Ltd. Co., located in Nigde City where the whitest and purest CaCO3 t exist on site. As the most leading calcium carbonate manufacturer and the main supplier of limestone in Turkey, currently Niğtaş Micronized Calcite employs about 600 people in three different quarries with own reserves and two production plants (our reserves will be sufficient for around three hundreds years and have a very special characteristics). We have one of the whitest and purest calcium carbonate on the world, which is shown by many researches, for example by Ground and Precipitated Calcium Carbonate from Roskill.We are continuously expanding in our technology factors and have a big production capacity. To ensure the continuation of the existing quality, the samples taken from each stage of production are analyzed physically and chemically in the Quality Control Laboratory in accordance with TS - TS EN ISO standards.

Micaceous iron oxide (Fe2O3) is a pure, natural product in the oxide class of minerals. Its hardness according to Mohs is 6.0 to 6.5, with a density of 4.8g/cm³. In addition to standard types for heavy-duty corrosion protection, newly developed product types especially well suited for thin-film corrosion protection and also as a zinc dust replacement are available. For the ceramics and plastics industry, we supply micaceous iron oxide as a metallic effect pigment in very coarse, narrow grain size ranges.

GraphTHERM® - graphite optimised for heat conductivity. GraphTHERM® developed by Georg H. Luh GmbH especially for improved heat conductivity enable a thermal conductivity of 20 W/mK or more thanks to their special form. The mechanical properties or processability are not impaired even at a high filling degree of more than 60%. This combination of characteristics makes GraphTHERM® especially well suited for plastics applications. GraphCOND® - graphite optimised for electrical conductivity Special pre-treatment and grinding results in graphite particles that enable an effective electrically conductive network to be created even at a low material proportion. A conductivity of >100 S/cm is possible in plastic. GraphCOND® features convincing properties and is versatile in application, for example in dissipative coatings or highly conductive compounds.

Graphite, like diamond, consists of pure carbon arranged in a hexagonal crystal system. One differentiates between natural and synthetic graphite depending on the extraction or production method. Graphite exhibits a unique combination of material properties due to the special crystalline composition of the layer structure.
