Using urine means there are other ions in the solution that will disturb the crystallization process. Calcium has been commonly seen as a hinder to the magnesium phosphate hydrate formation [37, 38], in which it affects the induction time, the shape, and the size of the magnesium phosphate hydrate crystal [39].

Passivation of heavy metals is one of the most efficient techniques to improve the quality of compost. Many studies confirmed the passivation effect of passivators (e.g., zeolite and calcium magnesium phosphate fertilizer) on cadmium (Cd), but passivators with single component could not effectively passivate Cd in the long-term operation of composting.

Bones are metabolically active organs. Their reconstruction is crucial for the proper functioning of the skeletal system during bone growth and remodeling, fracture healing, and maintaining calcium–phosphorus homeostasis. The bone metabolism and tissue properties are influenced by trace elements that may act either indirectly through the regulation of …

In general, calcium phosphate (CaP) is a well-known bone substitute that is similar to the mineral components of native bone tissue, and has been utilized as a treatment for bone diseases, because it enables resorption in the bone formation [11].However, to repair damaged bone tissue and accelerate new bone formation, the utilization of calcium phosphate still faces …

With calcium magnesium phosphate (MCPC) as a model, the effects of MCPC on the vascularization and neurotization in the process of wound regeneration were investigated. Herein, a series of MCPC/hydrogels with different concentrations (0–4%) of MCPC were synthesized. The results showed that MCPC could stimulate the migration behavior of ...

et al. 2019). In China, the total reserves of phosphate rock resources are high, but more than 80% is medium-to-low grade (Rukun 2004). Therefore, the ecient use of medium- and low-grade phosphate rock is an eective way to deal with the high-grade P rock crisis. Calcium-magnesium phosphate fertilizer (CMP) is one of

The protein-bound form of calcium accounts for approximately 40% of total serum calcium, of which 80% is bound to albumin and the remaining 20% is bound to globulins. 1 A total of 10% of the total calcium is bound to small anions, including bicarbonate, phosphate, citrate, and lactate. 1 The free, physiologically active calcium (often called ...

Characterization. Based on the theory of O b /Y b prepared by fertilizer [], four formulations of O b /Y b values were designed, respectively, and the batching schemes were shown in Table 2.In terms of characteristic fusion temperatures, the phosphate ore and dolomite with various O b /Y b values were tested to determine the suitable temperatures for the melting process.

Calcium, phosphate and magnesium are essential for human function and life. Each electrolyte is readily found in the human diet, and homeostasis is tightly regulated by the intestine, kidney and bone as well as other critical hormones, receptors and transporters. Disturbance to this balance can result in symptomatic disease and life-threatening manifestations. Calcium …

Additionally, magnesium phosphate cements (MPC) turned out to show very good biomechanical features, which are even better than clinically well-established calcium phosphate bone fillers . Since most of the implanted magnesium phosphate minerals are hydrated species, their processing and in vivo application usually follows a cementitious route ...

Processing of calcium and magnesium phosphate cements for bone substitution Dissertation zur Erlangung des naturwissenschaftlichen ... Ceramic materials like calcium and magnesium phosphate cements approximate these requirements due to their similarity to human bone composition. However, bone itself is a composite material of mainly
