303 results about "Bone ash" patented technology

Bone ash is a white material produced by the calcination of bones. Typical bone ash consists of about 55.82% calcium oxide, 42.39% phosphorus pentoxide, and 1.79% water. The exact composition of these compounds varies depending upon the type of bones being used, but generally the formula for bone ash is: Ca₅(OH)(PO₄)₃. Bone ash usually has a density around 3.10 g/mL and a melting point of 1670 °C (3038 °F). Most bones retain their cellular structure through calcination.

Method and apparatus for extracting carbon from biosome

InactiveCN101428784ASolid carbonBiological body
The invention relates to a method for abstracting carbon from animal and plant bodies, which comprises the following steps: after gas generated by cremating the animal and the plant bodies is subject to liquid filtration and solid absorption, physically separating carbon oxide gas from the gas, and then obtaining solid carbon through chemical replacement. The solid obtained by cremating is formed into carbon oxide gas after being subject to pyrolysis at the temperature of 800 to 900 DEG C, and then the solid carbon is obtained through the chemical replacement. A device for abstracting the carbon from the animal and the plant bodies comprises an incinerator, a liquid filter and a solid absorber which are connected through a pipeline in sequence; the discharge outlet of the solid absorber is connected with a carbon oxide gas physical separator and a solid carbon chemical replacer through a pipeline in sequence; and an evacuation opening is also arranged on the carbon oxide gas physical separator. The device further comprises a bone ash pyrolysis oven; and the gas outlet of the bone ash pyrolysis oven is connected with the solid carbon chemical replacer. By adopting invention, the carbon can be abstracted form organisms (including human and animal remains and plant bodies) and is further made into a monumental diamond souvenir.

A glaze material manufactured by utilization of tailings and a glazing process thereof

The invention discloses a glaze material manufactured by utilization of tailings. The glaze material comprises 40-65% of feldspar, 10-25% of quartz, 15-30% of iron ore mine tailings, 0-10% of limestone, 0-10% of kaolin and 0-10% of bone ash. The glaze material comprises following components by weight: 1-5 parts of K2O, 1-8 parts of Al2O3, 55-70 parts of SiO2, 1-5 parts of P2O5, 1-5 parts of Na2O, 1-8 parts of Fe2O3, 5-15 parts of CaO and 1-8 parts of MgO. The invention also discloses a glazing process of the glaze material manufactured by utilization of the tailings. The glazing process includes: adding the materials into a ball grinder and performing ball-milling, adding water, uniformly mixing, stirring and dissolving to obtain glaze slurry, with the fineness of the glaze slurry being controlled to be less than 0.01% of residue on sieve of a ten-thousand hole sieve; discharging the glaze slurry and stirring; sieving the glaze slurry with a sieve having a size of 200 meshes, applying the fully suspended glaze slurry onto the surface of a green body with the concentration being 38-46 baume degrees and the thickness of the glaze slurry on the surface of the green body being 0.2-1.2 mm; and subjecting the green body to high-temperature sintering, and cooling in furnace to room temperature after the sintering is finished to obtain a ceramic product. By adoption of a one-time sintering process, the product quality can reach that of secondary sintering and the product energy consumption is reduced.

Method for preparing positioning iron red crystal glaze

The present invention discloses a preparation method for positioning ferreous crystal; the preparation of the base glaze is that: potassic feldspar, quartz, kaoline, ocher, steatite, limestone and bone ash are mixed with ferric oxide for grilling; the proportion of the glaze slurry is 1.6-1.7 g / cm3; the preparation method of the crystal core is that: kaoline is mixed with ferric oxide for grilling and calcining and cooling to become grain powder; and then crystal core is pre-buried in the position for the blank body to form the crystal flower; the size Phi of the preburied hole is about 1mm; the quantity and distribution are adjusted according to the actual requirement; the base glaze is put on the ceramic blank body preburied with crystal core evenly; the thickness of the glaze level is controlled on 0.7-1.0mm; the semi finished product of the ceramic glaze is baked to the maximum temperature with oxidation blaze, and then is cooled into the room temperature. The present invention uses the common ceramic raw material and the positioning crystal measure to produce the positioning ferreous crystal glaze, which solves the shortcoming that the size and the distribution for the ferreous crystal flower is hard to be controlled; the method is a stable preparation method with simple process technical, wide baking temperature range, good stability, without needing middle temperature heat preservation; the produce cost is much lower.
