The influence of bone volume fraction and ash fraction on bone strength and modulus

Bone, 2001
Although bone strength and modulus are known to be influenced by both volume fraction and mineral content (ash fraction), the relative influence of these two parameters remains unknown. Single-parameter power law functions are used widely to relate bone volume or ash fraction to bone strength and elastic modulus. In this study we evaluate the potential

Using bone ash as an additive in porcelain sintering

Ceramics International, 2015
Abstract Calcined bovine bone (CBB) is generally used to manufacture high-quality porcelain known as bone china. In these products, the amount of bone ash is about 50%. However, it is known that CBB, in small quantities added to raw materials such as feldspars, can reduce the liquidus temperature and thus promote liquid-phase sintering. The purpose

Measurement of 90Sr in bone ash

Applied Radiation and Isotopes, 1998
Bone is a critical organ for the accumulation of many radionuclides, including 90Sr. A bone ash has been prepared by NIST to become a standard reference material and the assaying of the 90Sr activity concentration is reported. A radiochemical procedure, based on extraction chromatography using a crown ether, has been developed to separate Sr from the ...

Bone ash reinforced geopolymer composites

Journal of the American Ceramic Society, 2021
Abstract Potassium‐based, geopolymer composites were made with BASF ® metakaolin and Mymensingh clay‐derived metakaolin from Bangladesh. Since the natural Mymensingh clay contained 40 wt.% quartz, this same amount of quartz particulates was added to the BASF

Sifting through the Ashes and the Fragments of Bone

Common Knowledge, 2022
Abstract In this autobiographical essay, written in 2018 and previously unpublished, the late György Konrád intertwines his memories as a child during World War II with more theoretical reflections (and unanswered questions) on the war, its repercussions, its lessons.

Bone Density and Ash Studies in Avian Osteopetrosis

Avian Diseases, 1982
Bone density and ash were measured in diaphyses of osteopetrotic and normal chicken tibiotarsi. In lesions of less than one year's duration, osteopetrotic bone was less dense than disease-free bone. The new osteopetrotic bone yielded approximately the same ash content per unit bone dry weight, as did disease-free bone of comparable age, but there was ...

Ashing of bone: errors due to loss of CO2 and their correction

Journal of Bone and Mineral Metabolism, 2022
Ashing is widely used to determine weight fraction of water-free bone that is mineral, but no standard procedure exists and the range of techniques used spans a range of temperatures and times over which the amount of weight loss is variable. We show that variability is largely due to progressive loss of CO2 from CO3 2- ions in the apatite crystal ...

INFLUENCE OF BONE ASH ON THE REPAIR OF BONE

Archives of Surgery, 1940
In a previous publication 1 there was presented experimental evidence that bone ash aided ossification. In the reported experiments transplants of osteogenic tissue were cultured in the anterior chamber of the eye in a medium saturated with bone ash.

Interrelationships of bone ash and whole bone properties in the lactating and parous rat

Calcified Tissue International, 1987
Several investigators have studied the mechanical properties of long bones of rats and have found that bone strength may be associated with bone mineral content. In this study we examined further the interrelationships of whole bone properties and bone ash weight of the rat femur.
