Buyer FAQ

Boric Acid / Boron 17% questions

What is the boron content and formula of RunziChem's boric acid?
RunziChem boric acid is H3BO3 (CAS 10043-35-3), molecular weight 61.83 g/mol, with a typical boron content of about 17%. It is a white crystalline material produced to reference standard GB/T 538. The stated boron figure is typical for evaluation; the final value is confirmed on each batch COA.
What physical forms and particle sizes are available?
Boric acid is offered as white powder, fine 200–500 mesh micro-powder for faster dissolution and absorption, or in granular form for soil and blending routes. Choose the micro-powder grade for foliar sprays and fertigation, and granular for basal or dry-blend applications. Confirm the exact mesh or granule size with the export team.
How does boric acid dissolve and how is it used in crop nutrition?
Boric acid is water-soluble (roughly 5 g per 100 mL at 20 °C, more in warm water) and gives a weakly acidic solution. It is used as a boron source in foliar programs and soil applications where boron limits flowering, fruit set, and reproductive development. Confirm crop, rate, and local label requirements before use.
Are the listed assay and specification values guaranteed?
No. The specifications shown — boron content, appearance, and particle size — are typical or representative values for buyer screening only. The current batch certificate of analysis (COA) confirms the final assay, appearance, and quality. TDS, COA, and SDS are available on request before order confirmation.
