The present invention proposes a mixture comprising a linear copolymer comprising acrylic acid and 2-acrylamido-2-methyl propane sulfonic acid, water and one or more metal oxide ceramic nanoparticles with a mean particle size of up to 100 nanometers, preferably up to 60 nanometers, more preferably within the range between 20 nanometers and 60 nanometers, e.g., 40 nm. The mixture can be used in formation of doughs which are suitable for green machining. Molar ratio between acrylic acid and 2-acrylamido-2-methyl propane sulfonic acid in the copolymer can optionally be within the range between 0.8:1 and 1:0.8. In the mixture, the linear copolymer can be present at a concentration within an optional range between 1 wt.% and 2 wt.% based on total solid content. In the mixture, the one or more metal oxide ceramic nanoparticles can be present at a concentration within an optional range between 60 wt.% and 70 wt.%. The present invention further proposes a method for obtaining such mixture. |
