Investigation of spodumene-bearing rock as a flux for bone china production [PDF]

Materials Research, 2013
The use of a waste from mineral processing, a spodumene-bearing rock, was investigated as a flux for bone china composition, partially replacing feldspar. The effect of lithium oxide in bone china body was favorable for reducing firing temperature.

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Evaluation of the Nutrient Components of Flours, Color Profile, and Sensory Qualities of Cake From Wheat and Celosia argentea Seed Blends

Future Postharvest and Food, EarlyView.
Composite flour was developed with 5%, 10%, 15%, and 20% inclusion of Celosia seeds flour. The flour was used in the production of cake. Cake made with 5% composite flour compared favorably with cake from 100% wheat flour. ABSTRACT Nutritional benefits and physical appearance are of great importance in determining the acceptance of confectionary ...

Separation of trichothecene mycotoxins in a matrix of hemp (Cannabis sativa L.) seed, and quantification of deoxynivalenol in hemp grain infected with Fusarium graminearum

JSFA reports, EarlyView.
Abstract Background Fusarium graminearum, one of the causal agents of ear rot in maize and head blight of cereal grains, also infects hemp (Cannabis sativa L. containing a maximum of 0.3% tetrahydrocannabinol or THC). This fungal pathogen produces trichothecene mycotoxins when it infects maize and cereal grains, but little is known about its production
