Laboratory routes to the solvent-free materials are numerous. A well documented route involves the thermal decomposition of diazonium salts of [BF 4] −: [11] [PhN 2] + [BF 4] − → PhF + BF 3 + N 2. It forms by treatment of a mixture boron trioxide and sodium tetrafluoroborate with sulfuric acid: [12] 6 Na[BF 4] + B 2 O 3 + 6 H 2 SO 4 → 8 ...

Boron trifluoride etherate, strictly boron trifluoride diethyl etherate, or boron trifluoride–ether complex, is the chemical compound with the formula BF 3 O(C 2 H 5) 2, often abbreviated BF 3 OEt 2.
The acidity of fluoroboric acid is complicated by the fact that its name refers to a range of different compounds, e.g. [H(CH 3 CH 2) 2 O] + [BF 4] − (dimethyloxonium tetrafluoroborate), [H 3 O] + [BF 4] − (oxonium tetrafluoroborate), and HF·BF 3 (hydrogen fluoride-boron trifluoride 1:1 adduct) – each with a different acidity.
In other words, Digital Geometry is programmable CAD. Historically the CAD term has been used for any 3D model representations. In many situations Computer Aided Design term becomes misleading. In traditional CAD 3D model is the objective. In Digital Geometry 3D objects are an intermediate step for calculations or simulations.
