Purpose: Purpose of this paper is to present results of the ceramization of biomorphic materials under different conditions. The aim of the study is to characterize the structure and the usefulness of the material resulting in further applications. Possibility of making a porous material made up of different phases and composition depending of high temperature process and the input material has been demonstrated. Design/methodology/approach: Pyrolisis was done on wood pine samples. Obtained char was subjected to infiltration with solution of titanium alkoxide precursor. After the process of infiltration and drying ceramization subjected in carbon-TiO2 char in three different conditions. Scanning microscopy investigation and XRD analysis were carried out. Structure and phase composition of various biomorphic materials was determined and compared. Findings: The result of the processes was to obtain various biomorphic products, for which the phase composition and chemical depending on the atmosphere participating during annealing were investigated. Research limitations/implications: Biomorphic material is deformed due to loss of integrity during the manufacturing process, which depends on the gaseous atmosphere under annealing processes. Further studies are limited by poor durability and structure easy to pulverize. Practical implications: reinforcement of composite materials, active filters, precursors to ceramic nanopowders Originality/value: comparing biomorphic material prepared under different conditions. Comparison of the porous structure of TiC/C biomorphic material with pure TiO2 after high temperature process and TiC ceramic wood.

Przedstawiono wyniki badań zużycia materiałów drzewnych w Polsce przez gospodarstwa domowe oraz w miejscach użyteczności publicznej. Posługując się metodą wskaźników modelowych dokonano po raz pierwszy kwantyfikacji zużycia materiałów i wyrobów drzewnych w tej dziedzinie. Zużycie materiałów drzewnych obliczono dla dwóch kategorii: zużycia produkcyjnego (przez krajowy przemysł drzewny) i zużycia finalnego (przez ostatecznych konsumentów krajowych).

This article presents results of research into consumption of wood materials in households and public utility places, that is in the sphere connected with trade, operation of offices, hotels, schools, hospitals and other structures, as well as their surroundings such as parks, garden, playgrounds and areas intended for sport and recreation in Poland. For the first time in Poland quantification of consumption of wood materials and products in this area was done using the model indices method. In line with the aim of the study consumption of wood materials was calculated for two consumption categories: production consumption (by domestic wood industry) and final consumption (by domestic end-users).

Artykuł przedstawia wyniki badań, pozwalających na kompleksową analizę rynku materiałów i wyrobów drzewnych wykorzystywanych w budownictwie. Stosując metodę wskaźnikową, po raz pierwszy w Polsce dokonano kwantyfikacji zużycia materiałów i wyrobów drzewnych w tym dziale gospodarki, z uwzględnieniem zarówno rodzajów materiałów, jak i segmentów rynku budowlanego.
