Impact of Ball Milling on the Microstructure of Polyethylene Terephthalate [PDF]

open access: yesChemSusChem, Volume 18, Issue 4, February 16, 2025.
Milling PET: This study investigated the impact of ball milling at different frequencies on polyethylene terephthalate (PET) samples of different crystallinity and particle size. Percent crystallinity (from both differential scanning calorimetry and powder X‐ray diffraction), particle size, as well as size and shape of the milled PET were measured ...

On-Site Identification of Pottery with pXRF: An Example of European and Chinese Red Stonewares

open access: yesHeritage, 2021
The invention of European hard porcelain, which aims at imitating kaolin-containing white paste of Chinese porcelain, had been started by the development of the technology of “red porcelain”, so-called “Jaspisporzellan” by Johann Friedrich Böttger in the

Processing of porcelain stoneware tile using sugarcane bagasse ash waste [PDF]

open access: yesProcessing and Application of Ceramics, 2015
Large amounts of waste materials are discarded in the sugarcane industry. This work investigates the reuse of sugarcane bagasse ash waste as an alternative raw material for porcelain stoneware tile bodies, replacing natural quartz by up to 5 wt.%.

Ceramics based on concrete wastes prepared by spark plasma sintering [PDF]

open access: yesProcessing and Application of Ceramics, 2021
An effective utilization technique is required to recycle fine aggregate in concrete waste because the presence of residual waste cement reduces the quality of the recycled concrete.

FLASH sintering of porcelain stoneware: Effect of composition modifications

open access: yesJournal of the European Ceramic Society, 2023
In this work, we have exploited FLASH sintering as an alternative sintering process in the production of porcelain stoneware. FLASH sintering of porcelain stoneware occurred at temperatures ∼ 1020 °C, for 500 V cm-1, 2 mA mm-2 in 30 s. These conditions are significantly less severe than those typically applied in its conventional sintering, 1150–1250 ...

Re‐assessing regional chronologies for island southeast Asian voyaging to Aboriginal Australia

open access: yesArchaeology in Oceania, Volume 58, Issue 3, Page 245-274, October 2023., 2023
ABSTRACT According to written histories, trepang fishers from Island Southeast Asia (“Makassans”) frequented coastal northern Australia from c.1750 to 1907 CE. Yolŋu oral traditions and old Austronesian borrow words in coastal Aboriginal languages suggest a long and complex history of foreign voyaging to northern Australia.

Comparison of Methods for Determining the Water Absorption of Glazed Porcelain Stoneware Ceramic Tiles [PDF]

open access: yesMaterials Research, 2017
This work evaluated the water absorption of glazed porcelain stoneware ceramic tiles using three different methods. Two methods were based on a procedure of boiling in water, specified by standards ISO 10545 and ASTM C373, and the third was the vacuum ...
