Uranium concentration in bone of Beijing (China) residents
Science of The Total Environment, 1990Bone samples were obtained from 65 Beijing residents who had died from illness or old age. The concentration of uranium in the bone ash was determined by the laser-fluorimetric method. The concentration varied between 0.014 and 0.390 microgram g-1 ash, with a median value of 0.067 microgram g-1 ash; the 25th and 75th percentiles were 0.045 and 0.1 ...

Fabrication and characterization of bone china using synthetic bone powder as raw materials
Ceramics International, 2016Abstract The synthetic bone powder was studied as a raw materials for bone china, completely replacing natural bone ash raw materials. The physical and thermal properties of samples obtained by the two bone powders were tested and comparatively studied.

First discovery of a bone handaxe in China
Quaternary International, 2017Abstract Handaxes, the characteristic tool of the Acheulean industrial complex, are predominantly made of stone. Handaxes made of bone are much less common. Only a few have been reported, from sites in Africa, Europe and western Asia. In this study we report a bone handaxe from Chongqing, southwest China, which represents the first bone handaxe ever ...

The preservation of fossils over long periods of geological history usually has special characteristics, and the specific conditions for successful fossilization have not been established yet. Triassic bones from SW China are characterized by an exceptionally broad variation in the style of preservation.

A Note on Translucency of Unglazed Bone-China Body
Transactions of the Indian Ceramic Society, 1984Translucency of unglazed bone-china pieces of thickness 1–2 mm, fired at different temperatures, was measured. It was found that samples fired at temperatures less than 1150°c showed hardly any translucency for a reasonable soaking time. Thickness of samples was less critical than the firing temperatures.

Elimination of discolouration in reformulated bone china bodies
Journal of the European Ceramic Society, 2005Abstract In order to reduce the thermal expansion coefficient (TEC) to make it fit high scratch resistance glazes, which have lower TEC values, bone china body is reformulated. This is done by reducing the amount of bone ash, which is responsible for the formation of a crystalline phase of β-tricalcium phosphate (β-TCP) with a high TEC value and ...

Durability properties of bone china ceramic fine aggregate concrete
Construction and Building Materials, 2018Abstract To suggest an alternative raw material for concrete, its role in the hydration mechanism and water durability characteristics is required to be understood. This article assesses the water based durability properties of concrete containing bone china ceramic fine aggregates (BCCFA). For this study, BCCFA was utilised as 0%, 20%, 40%, 60%, 80%

West China Technique of Alveolar Bone Grafting
2013According to the biomechanical analysis of the effects of bone grafting in the repair of cleft palate described in the last chapter, we found that repairing cleft palate with bone grafts can stabilize and support the maxillary dental arch, protect the arch against the pressure of the lip, cheek and tongue, and effectively prevent tissue collapse.
