Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Effect of Marble Waste Powder as Cement Replacement on The Concrete Mixes
مجلة العلوم البحتة والتطبيقية, 2020 Leaving the waste materials to the environment directly can cause environmental problem. Waste reuse was therefore emphasized. Waste can be used to produce new products or can be used as additives so that natural resources are used more efficiently and ...

Advanced Engineering Materials, EarlyView.Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Analytical magnetic field analysis of Halhach magnetized permanent-magnet machines [PDF]
, 2004 We develop analytical models for predicting the magnetic field distribution in Halbach magnetized machines. They are formulated in polar coordinates and account for the relative recoil permeability of the magnets. They are applicable to both internal and
