Magnesium borates are compounds including mainly magnesium (Mg), boron (B) oxygen (O), and hydrogen (H). Magnesium borates are traditionally famous for their strong thermoluminescence, mechanical and thermal features due to their high elasticity coefficient, corrosion, and heat resistance. Because of being beneficial, especially in the applications such as thermoluminescence and X-ray screening, and ease of synthesis, magnesium borates are produced by using different experimental procedures exhibiting different characteristics. Main traditional synthesis techniques can be classified as liquid state and solid-state synthesis methods. With the help of novelties in synthesis technology, new techniques are beginning to emerge in magnesium borate syntheses such as hybrid synthesis, ultrasound, microwave, and capping agent addition. The strengthened characteristics of the compounds would lead to new applications such as stomach cancer chemotherapy and wastewater treatment. In this chapter, it is aimed to make a comparison between the characteristics of synthesized magnesium borates and their properties. In addition, new types of magnesium borates obtained by various synthetic techniques are expected to be useful for industrial applications such as space technology, radiation dosimetry, X-ray screening, ion batteries, and hydrocarbon reaction catalysis. Such classification of properties and the synthesis techniques will enlighten the relationship between the characteristics and novel applications of magnesium borates.

“…Aluminum borate (AB) has two stable compound forms of Al 18 B 4 O 33 and Al 4 B 2 O 9 in the Al 2 O 3 -B 2 O 3 binary with a variety of excellent properties, such as high strength, low thermal expansion coefficient, high melting point, high stability, and low cost. [1][2][3][4][5] Thus, AB are widely applied in ceramic-based composites that have potential uses in many fields, such as heterogeneous or ceramic-based materials brazing joints, [6][7][8][9] aerospace, 10 refractory, 11 cracking catalyst, and filtering materials. 12,13 There are many different ways to heterogeneous materials joining.…”

Ceramics with aluminum borate whiskers (ABWs) were prepared from H3BO3 and Al2O3 reagent, with and without 6 wt% MnO2 used as an addition. The microstructures, phase composition, and crystal structure of the ceramics were analyzed via scanning electron microscopy, energy dispersive spectroscopy, and X‐ray diffraction, respectively. The results show that MnO2 is an effective addition for enhancing the flexural strength of ceramics. The MnO2 could lead to the distortion of lattice, and improve the mechanical strength via a solid solution strengthening mechanism. Moreover, the content of H3BO3 and the sintering temperature were also key factors in the manufacture of optimal ceramics. The ceramic made from 6 wt% MnO2 addition, 25 wt% H3BO3, and sintered at 1200°C, showed the highest flexural strength of 88.5 (±1.9) MPa, and had a bulk density of 1.64 g/cm3 and porosity of 44.2%.
