The refractory materials or refractories are heat-resistant materials, that do not decompose by heat, pressure or chemical attacks. Elfusa is today the largest company of Latin America in the Fused Aluminum Oxides sector and Sintex Minerals distributes its refractories in North America and Canada.

AL is a white aluminum oxide obtained from the fusion of calcined alumina in electric arc furnaces. It is recommended for refractory applications in which purity, chemical stability and high refractoriness are issues to be considered.

ALOCAL is a brown fused aluminum oxide obtained from the fusion of high quality bauxites in electric arc furnaces. It is heat treated in a rotary kiln at high temperatures and magnetic treated. These procedures guarantee low iron content. ALOCAL is recommended for refractory applications.

ALOTAB is a brown fused aluminum oxide obtained from the fusion of high purity bauxites in electric arc furnaces. Due to its high content of Al2O3 and low iron content ALOTAB is recommended for refractory applications.

ALP is a off white fused aluminum oxide obtained from the fusion of calcined alumina and small quantities of chromium oxide in electric arc furnaces. It is recommended for refractory applications where chemical stability and high refractoriness need to be considered.

AR es un óxido de aluminio fundido marrón obtenido a partir de la fusión de bauxitas de alta pureza en hornos de arco eléctrico. Presenta una excelente relación costo/beneficio, de ser recomendado para la aplicación refractario donde un alto contenido de hierro no es un problema. AR divide más grande que 2.00 mm no se recomiendan para los refractarios moldeados utilizados a temperaturas superiores a 1.300 ºC.

ELECTROCARB® Black Silicon Carbide contains some free silicon (Si) and carbon (C) and is not as pure as green SiC. It is ideal for a wide variety of applications including bonded and specialty refractories, metal-matrix composites, kiln furniture, and many more.

C.R. FINES - Black Silicon Carbide DCF is collected from the dust collector systems connected to the crushing and grading systems of our #1 grade silicon carbide. It is ideal for general refractory applications.

Green Silicon Carbide is extremely pure. It can be manufactured into many complex bonded shapes for many applications including wear resistant seals/rings/nozzles, coatings, metalmatrix composites, kiln furniture, silicon carbide heating elements, body & vehicle armor, and many other applications.
