[1] Related compounds include aluminophosphates, which have aluminium instead of boron, gallophosphates,[2] with gallium in place of boron, and by substituting the phosphate: boroarsenates, boroantimonates, and vanadoborates.
[2] Solvothermal synthesis uses a non water solvent such as ethylene glycol to dissolve the product.
[3] The hydrothermal method heats the ingredients with water under pressure up to 200 °C.
[2] The ionothermal synthesis method uses an ionic liquid such as 1-alkyl-3-methylimidazolium bromide as a solvent.
