Saint-Gobain SEFPRO
French multinational refractory materials company
Saint-Gobain SEFPRO (Sintered and Electrofused Products), founded in 1929, produces refractories for the glass industry. The company consists of plants, sales offices and Research and Development Centers employing over 2200 people across four continents, with headquarters in Le Pontet, Vaucluse, France. The group belongs to the Innovative Materials division of the Saint-Gobain group.
History
The first electro-fused product was invented and developed in the 1920s by the laboratory of Corning Glass Works, the American glassmaker partnered with Hartford Empire Co. Production began at Corhart Refractories Co., a Corning subsidiary, in 1927.
In 1929, a joint venture between Corning and Saint-Gobain, another leading glassmaker, established L'Electro-Réfractaire in Modane, France, with their principal product the Corhart Standard. By 1940, the company was producing 2000 tons of the product per year. In 1942, a new, even more hard-wearing product was introduced: Corhart ZAC. New, pure raw materials were used, such as Zircon, Alumina and Silica (later known as AZS). During the Second World War, the Modane factory was destroyed. In 1947, a new production site was selected in Le Pontet, located in the department of Vaucluse in France, some 350 km from the original location.

Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 9, 2026. The linked authority identifier is Q25042682. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
