According to GlobalData’s company profile on RHI Magnesita, was a key innovation area identified from patents. RHI Magnesita's grant share as of May 2024 was 60%. Grant share is based on the ratio of number of grants to total number of patents.
A recently granted patent (Publication Number: US11981609B2) discloses a raw material designed for producing refractory products with specific characteristics. The raw material must contain Al2O3, MgO, and CaO in precise proportions, with open porosity ranging from 30 to 60 volume %. Additionally, the particle size of the batch used to produce the raw material should have a d90 value less than 50 µm. The chemical composition of the raw material is crucial, with specific limits on the presence of SiO2 and Fe2O3, as well as requirements for raw density and bulk weight.
Furthermore, the patent includes claims related to the method for producing the refractory product using the specified raw material, emphasizing the importance of the chemical composition and open porosity for achieving the desired properties. The patent also covers the refractory product itself, highlighting the composition and characteristics required for it to be classified as such. The refractory product can take the form of refractory concrete and may include calcium-aluminate cement in addition to the raw material, with a specific proportion range specified for the raw material within the product.
