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 ...

Standardization of Antibacterial Bone China
The developments of antibacterial ceramics technology were introduced. A new type of antibacterial agent used in bone china, multifuntional healthy ceramic materials antibacterial mechanism, was discussed. With the quick development of antibacterial bone china technology and market, it was necessary to estabish the antibacterial bone china standard.

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 ...

Bone china formulated with waste glass
Advances in Applied Ceramics, 2013AbstractAbstractBone china is known for its technical and aesthetical quality with distinguishable whiteness, brightness and high mechanical strength. In this work, the use of waste glass was investigated in a bone china composition. This makes the production of this porcelain even more interesting from the environmental point of view, since most of ...

Microstructural evolution in bone china
British Ceramic Transactions, 2000Abstract Phase and microstructural evolution in model bone china bodies was determined by XRD and electron microscopy of quenched samples fired for 3 h at 600–1500°C. Unfired but shaped bone china comprised bone ash and clay agglomerates (≤70 μm) in a matrix of smaller (from submicron to 10 μm) mixed clay, feldspar, and bone ash particles.

Non-equilibrium microstructure of bone china
British Ceramic Transactions, 2000AbstractCommercial bone china microstructures are far from equilibrium consisting of distinct regions of lath-like (0·4–10 μm) anorthite and spheroidal (1–3 μm) β-tricalcium phosphate (β-TCP) nodules embedded in a heterogeneous composition glass along with isolated irregular (≤30 μm) α-quartz crystals.

Constitution of Bone China: II, Reactions in Bone China Bodies
Journal of the American Ceramic Society, 1955The reactions which occur on firing bone china are described and discussed with reference to the phase data for the system lime‐alumina‐phosphorus pentoxide‐silica. X‐ray examination of variously fired china bodies indicates that up to approximately 1000°C.
