Abstract
This work examines the reinforcement of reaction-hardening phosphate materials (phosphate cements) for bone implants based on isomorphically cation-(Na+, K+) and anion-(\({\text{SiO}}_{4}^{{4 - }}\), \({\text{SO}}_{4}^{2}\)) substituted tricalcium phosphate (β and α-TCP, Ca3(PO4)2), which are reinforced with silicate (basalt-based) fiberglass. The resulting materials were characterized by XRD and SEM methods, mechanical compression tests were carried out, the setting times of cements were determined, and changes in the pH of aqueous medium in contact with the cements under study were measured. Analysis of microstructure showed that the reinforcing fiber surface, upon contact with the matrix of hardening cement, is partially corroded with the formation of phosphate microparticles on it. Using the pH-metry method, it was found that samples with prolonged contact to water do not significantly change the value of the pH of the aqueous environment, which remains close to the neutral range from 5 to 7.5, favorable for further biological tests.
Abstract This work examines the reinforcement of reaction-hardening phosphate materials (phosphate cements) for bone implants based on isomorphically cation-(Na+. K+) and anion-({\text{SiO}}_{4}^{4 - }\})、K+）和阴离子（{\text{SiO}}_{4}^{4 - }}\), \({\text{SO}}_{4}^{2}\)）取代的磷酸三钙（β 和 α-TCP，Ca3(PO4)2），并用硅酸盐（玄武岩基）玻璃纤维对其进行加固。通过 XRD 和 SEM 方法对所得材料进行了表征，进行了机械压缩试验，测定了水泥的凝结时间，并测量了与所研究水泥接触的水介质 pH 值的变化。微观结构分析表明，在与硬化水泥基质接触时，增强纤维表面会被部分腐蚀，并在其上形成磷酸盐微粒。使用 pH 值测定法发现，长期与水接触的样品不会明显改变水环境的 pH 值，其值仍接近 5 至 7.5 的中性范围，有利于进一步的生物测试。
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
