In addition, Grecian Magnesite S.A. & Imerys Fused Minerals Hull have jointly developed a premium refractory electro-fused magnesia product, sold under the “PyrMag” brand name.

PyrMag is a high purity product (typical MgO 98,4%) with low levels of impurities, in all size fractions, exhibiting enhanced physical properties such as exceptionally high bulk density (3,54 g/cm3), and a large mean Periclase crystal size of 1300 microns.

PyrMag’s superior refractory properties makes it perfectly suitable for the production of high quality shaped or unshaped refractory products for use in the steelmaking, cement and nonferrous metals industries (e.g. MgO-C bricks, special castables, etc.); including other high temperature applications requiring high performance, low iron, refractory raw materials.

PyrMag is manufactured in electric arc furnaces in IMERYS facility in the UK, using as raw material, high purity cryptocrystalline caustic calcined magnesia from Grecian Magnesite’s Turkish affiliate, Akdeniz Mineral Kaynaklari AS (AMK).

PyrMag is available in granular, sized and powder forms i.e. 0-50mm, 3,15 – 5mm, 1,40-3,15mm, 0,45-1,40mm, -0,45mm
