    • Aqueous peroxidic solutions containing oxyboron species and a substoichiometric amount of alkali metal are suitable for subsequent processing under controlled precipitation conditions to form microcrystals. The subsequent process steps are often conducted by the customer at a distant location, so that the solutions are subjected to potentially lengthy storage periods and/or transportation stresses which can induce premature precipitation. The physical stability of such solutions can be enhanced, i.e. the storage period before precipitation lengthened, by incorporating therein an effective amount of cyclohexane-1,2-diaminotetra(methylene phosphonic acid), which is often at least 0.005 % up to 1 % w/w of the solution and advantageously can be selected in the range of from 0.01 to 0.1 % w/w. In such solutions the alkali metal:boron mole ratio is preferably 0.5:1 to 0.67:1, the oxyboron content is particularly from 3 to 8 % w/w, calculated as boron and the mole ratio of available oxygen to boron is particularly 0.9:1 to 1.2:1.
    • 含有氧基硼类物质和亚化学计量的碱金属的过氧化物水溶液适用于随后在受控沉淀条件下的处理以形成微晶。 后续处理步骤通常由客户在远处进行,使得溶液经受潜在的冗长的储存期和/或可导致过早降水的运输应力。 通过在其中加入有效量的环己烷-1,2-二氨基四(亚甲基膦酸)可以提高这种溶液的物理稳定性,即沉淀延长之前的储存期,其通常为至少0.005%至1%w / w的溶液,并且有利地可以在0.01至0.1%w / w的范围内选择。 在这种溶液中,碱金属:硼的摩尔比优选为0.5:1至0.67:1,氧硼含量特别为3至8%w / w,以硼计算,可用氧与硼的摩尔比特别为0.9: 1〜1.2:1。
