Üleksit, borik asit üretiminde kullanılan
en önemli minerallerden biridir. Borik asit, heterojen katı-sıvı
reaksiyonlarında yan ürün olan jipsin kristallenmesine sebep olan, sülfürik
asitin üleksitle reaksiyonundan elde edilir. Bu çalışmada H₂SO₄
çözeltilerinde, ultrasesin üleksitin çözünmesi üzerine etkisi incelendi.
Reaksiyon süresi ve sıcaklık parametere olarak seçildi. Ultrasesli ortamda,
reasiyon sıcaklığı arttıkca B₂O₃’in çözünme oranı azaldı.
Yine ultrasesli ortamda, reaksiyon ilerledikçe, CaO’in  dönüşüm oranı 30˚C ve 50˚C’ de arttı. Ancak
bu oran 70˚C’ de azaldı. Oysa, ultrasessiz ortamda B₂O₃
ve CaO’in çözünme fraksiyonları sıcaklık arttıkca arttı.
