The relationship between the dislocations, the inclusions and the growth striations in YAG single crystals were studied with birefringence topography. The experimental evidence shows that the inclusions are adsorped preferentially at the outcrops of dislocations at the solid-liquid interface and the relative sizes of the inelusions correspond to the heights of growth-steps which are related to the normal components of Burgers vectors of dislocations.

The important role of a collector (paraffin soap) in the selective flocculation of ilmenite with polymer was described. The suspension of ilmenite-feldspar was conditioned with a small amount of collector prior to an addition of polymer. As a result, the flocculation selectivity of the system was improved singniflcantly as compared with that only polymer added. This may primarily be attributed to the selective adsorption of the collector on the ilmenite surface and to the consequent hydrophobic flocculation...

The important role of a collector (paraffin soap) in the selective flocculation of ilmenite with polymer was described. The suspension of ilmenite-feldspar was conditioned with a small amount of collector prior to an addition of polymer. As a result, the flocculation selectivity of the system was improved singniflcantly as compared with that only polymer added. This may primarily be attributed to the selective adsorption of the collector on the ilmenite surface and to the consequent hydrophobic flocculation of ilmenite particles. Polymer added subsequently adsorbed on the remainder sites on the ilmenite surface and associated with the collector molecules further, so that the selective flocculation and the separation of the suspension of ilmenite-feldspar fine particles were achieved.

本文阐述了捕收剂在高分子选择性絮凝中的作用。在添加高分子絮凝剂之前,将捕收剂(氧化石蜡皂)与钛铁矿-长石悬浮体系预先调浆,与单独使用高分子絮凝剂相比,絮凝选择性大大提高。这可以初步归因于捕收剂选择性优先吸附于钛铁矿表面并形成钛铁矿的疏水性絮凝。随后添加的高分子絮凝剂吸附于钛铁矿表面剩余空位并与捕收剂分子进一步缔合,从而实现钛铁矿-长石的有效的选择性絮凝分选。

测定了不同摩尔比的全氟辛酸钠(7CFNa)-十烷基硫酸钠(C_(10)SNa)混合水溶液(加NaCl,恒定离子强度μ=0.1m)的表面张力和界面张力(正庚烷-水溶液界面张力)。由表(界)面张力-浓度关系求出混合体系的表(界)面吸附和临界胶团浓度(cmc)。结果表明:(1)7CFNa和C_(10)SNa在μ=0.1m的溶液中,cmc相近,两者表面活性相近;但7CFNa降低水表面张力的能力较强,在cmc时的表面张力可低达~23mNm~(-1)。因此,在混合溶液的表面上,7CFNa的表面活性较高,优先吸附于表面。对于各种摩尔比的混合溶液,7CF~-在表面层中的比例皆大于在溶液内部的比例。(2)正庚烷-水溶液界面上的吸附与表面吸附截然不同。7CF~-在界面吸附层中的比例低于溶液内部,表明其吸附能力比C_(10)S~-为弱。这是由于界面一边的正庚烷与C_(10)SNa碳氢链之间的作用大于与7CFNa碳氟链之间的作用。亦即碳氟链与碳氢链“互憎”作用在界面上的表现。(3)在不同摩尔比的混合溶液中,各组分的cmc接近一恒值,进一步说明混合溶液中存在碳氟链与碳氢链间的互憎作用,以致两种表面活性剂在混合溶液中(有过量...
