Abstract
Description
Изобретение относится к составам стекол, предназначено для получения стеклокристаллических материалов, которые могут быть использованы для имплантаций. The invention relates to glass compositions, is intended to obtain glass crystalline materials that can be used for implantation.
Известно стекло [1] , включающее мас. % : SiO2 50-63 CaO 22-23 MgO 13-21 Al2O3 1-3 Na2O 0,5-20
Недостатком данного стекла является то, что для получения стеклокристаллического материала его необходимо подвергнуть термообработке в течение 1-1,5 ч, что приводит к значительному удорожанию материала. Кроме того, такое стекло не обладает поризованностью.Known glass [1], including wt. %: SiO 2 50-63 CaO 22-23 MgO 13-21 Al 2 O 3 1-3 Na 2 O 0.5-20
The disadvantage of this glass is that in order to obtain a glass-crystalline material it must be subjected to heat treatment for 1-1.5 hours, which leads to a significant increase in the cost of the material. In addition, such glass does not have porosity.
Наиболее близким к предложенному является стекло для стеклокристаллического материала, включающее, мас. % : СаО 40-50; SiO230-40; P2O5 10-25; MgO 0-10, другие добавки 0-10 и углерод (0,001-1 мас. ч. на 100 ч. материала) [2] .Closest to the proposed is glass for a glass crystal material, including, by weight. %: CaO 40-50; SiO 2 30-40; P 2 O 5 10-25; MgO 0-10, other additives 0-10 and carbon (0.001-1 wt. Parts per 100 parts of material) [2].
Недостатком известного материала является низкая пористость. A disadvantage of the known material is its low porosity.
Технический результат заключается в увеличении поризованности. The technical result consists in increasing porosity.
Для этого стекло для стеклокристаллического материала содержит следующие компоненты, мас. % : SiO2 27-51 CaO 25-46 MgO 3-12 P2O5 5-17 C 2-3
В качестве сырья для получения стеклокристаллического материала используют некондиционный песок, получаемый в результате флотации фосфоритов на химических заводах, содержащий Р2О5. Смешанные в заданных количествах компоненты засыпают в кварцевые тигли емкостью от 1 до 3 л. Варку производят в тигельной печи при температуре 1500оС и выдерживают до 1 ч.For this, glass for a glass crystal material contains the following components, wt. %: SiO 2 27-51 CaO 25-46 MgO 3-12 P 2 O 5 5-17 C 2-3
As raw materials for the production of glass crystalline material, substandard sand is used, obtained as a result of flotation of phosphorites in chemical plants, containing P 2 O 5 . The components mixed in predetermined quantities are poured into quartz crucibles with a capacity of 1 to 3 liters. The cooking is carried out in a crucible furnace at 1500 ° C and held 1 hour.
Выработку производят при той же температуре. Далее полученную стекломассу дробят. Термообработку производят при температуре 850оС как до, так и после дробления.Production is carried out at the same temperature. Next, the resulting molten glass is crushed. The heat treatment is performed at a temperature of 850 ° C both before and after crushing.
Полученный материал имеет белый цвет. Поризованный стеклокристаллический материал получают в плавильно-конверторном агрегате (ПКА). Температура, при которой происходит сплавление, равна 1500оС. Расплав выдерживают 0,5 ч и отливают на разливочную площадку для остывания. Остывшую массу дробят и подвергают термообработке при температуре 950оС.The resulting material is white. Porous glass crystal material is obtained in a smelting-converter unit (PKA). The temperature at which fusion occurs, equal to 1500 C. The melt was allowed to stand for 0.5 hours and cast onto the casting area for cooling. The cooled mass is crushed and subjected to heat treatment at a temperature of 950 about C.
Изобретение поясняется конкретными составами стекол, мас. % : The invention is illustrated by specific compositions of glasses, wt. %:
